C# Solution into SVN projects - c#

Apologies if this has been asked before, but I've been unable to find the information I'm looking for.
I'm working on a large C# solution, which contains a number of components shared with another 2 solutions.
My aim is to check the whole thing into an SVN server, but I'm uncertain the best way to go about this.
When I worked in a Java dev team, we used an SVN server and Maven to handle builds, so our projects were entirely modular.
Each project was checked into SVN as a separate entity, and Maven handled the retrieval of compiled artifacts, and all was well.
I would like to replicate this sort of strategy in C# using VS 2013, but I'm uncertain how to go about this other than checking in each project of the solution into its own SVN project.
This is not an issue as such, but we have 2 other solutions which use projects contained in our main solution.
If I were to check in the entire solution (as I would wish to so the solution files themselves are version controlled), the SVN checkout/checkin could become rather complex and unwieldy.
If I check in individual project from within the solution directory, I will need to come up with an svnignore policy that will stop the projects contained within the solution directory from being checked in to SVN again.
The SVN in this case will not be used for team development, but for handling merges and storing finalised tags, so will be running locally on my machine.
I'm pondering TFS as an alternative, but have no experience with it, so I'm unsure if it can be used in this way.
Can anybody advise if my proposed approach is actually possible for VS projects using SVN, or whether TFS would be a better option?
I would be happy to use an entirely different solution for source control, however I'm less inclined toward using GIT. For the uses we're intending, a more traditional client/server approach would suit out needs better, and the relearning time required for GIT just can't be spared at the moment.
If there are other posts/guides/existing advace on this subject that somebody can point me to, I would be grateful.
Many thanks.

You can achieve it by TFS. Need to check in the entire solution(all in source control) and use local workspace, get the files mapping in local. For VS, all your source code are locally, just like in the local development environment. All your need is editing your code, checking in server, resolving the conflict, getting latest version.You even don't need to manually check out your solution(For local workspace in TFS, will automatically check out files).
Tree view of your project as below.
-Your project
-solution1
-solution2
-Main solution
-common folder(which put the shared components)
You just need to add the common folder associated with the three solutions. Every change in the common folder will also defect with the three other solutions when checked in.

Best practice for referencing a project or assembly in a solution

I started at a new company which manages multiple projects (around 30). However, all their projects are in one git-repository. I know wanted to split all our projects into one git-repository per project. To achieve that I went ahead and extracted every folder into a new folder, containing it's own git repository.
However, some references were broken. While investigating I found that project referencing was done in multiple ways, dependent on the project
Including the entire solution/project in the current solution.
Referencing the .csproj-file of another solution.
Referencing the built .dll (bin/debug).
In my opinion, the first way should not the way to be, right? This seems like a way too big overhead. So I'm split between 2 and 3, and I would like to hear how you people are doing it?
Looking forward for your input!
It's normal to have code you want to share between multiple solutions.
For this, we use projects like 'Infrastructure' or 'Logging' with their own CI builds. When done, we create a release build which uploads the dll's to a private nuget server.
These projects are than included as dll's in the other projects through nuget and updated when needed. You also don't break other solutions when you change something in your logging, you have to update the logging version first.
What I do is to have a nuget server in the company or you can use Azure DevOps to do that: https://learn.microsoft.com/en-us/azure/devops/artifacts/get-started-nuget?view=azure-devops.
After you set the nuget server you can update/import the packages for each project. So, when you update the code of any project, post it to the nuget server and you can update all other projects.
Your question sounds like "How to split a solution into smaller solutions".
30 projects is not that much, At 30 C#-projects it's just the starting point to split your solution.The solution is the base for the Repository also.
If you analyze the dependencies of C#-projects, you certainly can form kind of clusters,
are there basics- referenced by everything, and almost front end parts, referenced by nothing.
Basic-Projects (Depends from Nothing, but referenced by many) Tend to be more stable and have less frequent changes, it's also more dangerous to change, more danger of braking changes. It's good to make access to them more complicated (=put it in a different solution). You do not change it frivolously, just because you see the source code and you edit it.
The code and architecture becomes more cleaner, since programmers tend to use a wrapper, derived classes or interfaces to do, what they want to do, inside their active solution.
They do not change dependent solutions as fast and easy any more. So it stays more stable.
You can consider a Solution as a product of it's own, as a Library or Final Product.
So splitting projects in the aspect, what is potentially being used in upcoming projects in the next years, and what is being used as a product for one client only.
Suppose you start a new Product next week, what Projects would you most likely include there ? They belong into a library.
It's also simplifying life to new programmers, if you tell them "Just use it, you don't need to dig in the source code", or "get familiar with this solution only" if you group your C# projects into such clusters. They are not so overwhelmed by quantity.
Also the branching is done per solution, you create a branch on one solution per client request, and a branch of another solution to stay up to date with technology. This is much easier to handle with smaller bundles of projects.
Nuget-Server as proposed by others, is a good way to maintain updates. Without a Server you link to DLLs directly. If you do not have many updates, either you invest time in setting up the server, or in copying a few DLL's around, twice a year. One is not more complicated or time consuming as the other. Manual jobs done by different people cause the risk of human errors. But the task "copy all DLL's from one directory to another directory" might still work. Do not reference the output directory from one solution directly to the other solution. Put the "productive DLL" in a separate directory and do your update by saying "yes, I want to update - use it now". "Automated update" just if someone decides to built the other solution might cause trouble.

Visual Studio Project Backup

Right now I am saving my all visual studio projects in C drive.
Now I want to keep copy of that all projects in some other drive, so if my C drive get crashed then also I can access all projects.
So what is best way for that.
If I just make zip of current projects from C drive and paste it in another drive.
And when needed I extract it, then will it work OR any error will come.
Thanks for help in Advance.
If I just make zip of current projects from C drive and paste it in another drive.
Well you could do that but it's rather tedius; error-prone and rather brute-force. It's difficult to maintain history.
A better choice is to use some form of source control (SC) / software configuration management (SCM). SC is a tool for maintaining a code repository. It works by associating metadata about every source file and any changes you make.
e.g.
Git
Subversion
Microsoft TFS
Perforce
IBM/Rational ClearCase
Microsoft SourceSafe (ewww, retried thankfully)
Source control not only keeps a copy somewhere else (ideally a different computer) but it also allows you to
keep track of what changed
rollback a change
share with your friends or colleges
integrates nicely with your IDE of choice (VS) or command-line
But in this day and age there are plenty of free cloud-based solutions that offer you more than just acting as a code repository such as stats; wikis; bug tracking; and spiffy charts. Check out:
Microsoft Visual Studio Team Services (VSTS)
Github
Atlassian Bitbucket
Summary
Irrespective of whether you perform manual folder copies or use source control; both will lead to a copy of your code. However only the latter introduces workflows and due-diligence (via SCM) so that as you code you are unlikely to lose information due to the procedures and safeguards in place.
A word on file backup
If for some absolute reason you decide not to proceed with SC but rather stick with plain-old-file-backup then at least follow the fine wisdom of Scott Hanselman (MSFT) where he talks about file backup best practices:
I've got a number of backups because I practice the Backup Rule of Three.
3 copies of anything you care about - Two isn't enough if it's important.
2 different formats - Example: Dropbox+DVDs or Hard Drive+Memory Stick or CD+Crash Plan, or more
1 off-site backup - If the house burns down, how will you get your memories back?
...using apps like CrashPlan.
Scott will most likely agree that his plan wasn't intended for source code but at least you have 3 backups of files as he recommends.
See Also
Hanselman, S, "Is your stuff backed up? Recovering from a hardware failure"
Have a look at Visual Studio Team Services. You can add code to source control (I would use Git if I were you) and manage your projects there for free.
Having your code in a source control system has many benefits, like having history of each commit.
Next to that, VSTS has lots of opions like Continuous Integration / Continuous Deployment, Testing, project management support like making your project an Agile project.
What will you do if hard drive crash?
Code Management is a practice and there are many tools to help you to manage your code. Try GitHub or bitbucket
Moreover you can also zip the code and save on external disks but check how much risk is involved with your code.
You could use a .zip archive to back up your work, but this is slightly laborious and will likely include a number of files you do not need to get up and running again (for example the build output, nuget packages folders, etc.) which will bloat your archives.
A better option would be to use a Version Control System of some kind, which will allow you to back up those parts of the project/solution that actually need to be backed up while ignoring the parts that can be rebuilt from the code. A good walk through of what and why can be found in Version Control By Example, which also includes comparisons about different types of VCS as well as how to perform many of the usual tasks.
There are various free options out there, based on a number of different providers. As some examples, I've used the following services, and all of them will give you a free account, and some will also give you private repositories (so that random members of the public can't see your work if that's what you want):
GitHub - unlimited public repositories, uses Git.
BitBucket - unlimited private repositories, uses Git or Mercurial
Visual Studio Team Services - unlimited private repositories, uses Git or TFS
Using an online provider will give you the added benefit of the backups being on a third party - so if your disk fails you'll still have a backup, as well as the other benefits a VCS will provide (the ability to rollback to a specific point in time, annotations about changes, etc.).

Make changes to c# program without loosing older code

I'm a hobbyist programmer and I've created an application for my office. Every so often I need to improve the code, add features or fix issues that come up under certain circumstances - I've found bugs or ineffective coding even after 3-4 months of heavy usage of the application. The thing is that whenever I modify the code, visual studio saves the changes. This means that if I want to use the program I'll have to be really fast in coding and debugging or it won't build - and I won't be able to use it...
Is there any way to keep the old version of the program without having to save the complete project folder elsewhere? Like creating a new version but keeping the option to go back to the old - working - one...
What you are looking for is called source control.
There are many systems out there, two popular ones are subversion and Git.
Used properly, you will have a full history of each file you have in your project.
There are two other answers here regarding source control at the time I write this, but there is another angle on this as well.
You're executing your production copy from the development directory. Don't do this.
When you have developed the program to a stable version, make a copy of it somewhere else and use that copy. In this way you're free to keep developing on the software without destroying your ability to keep using the existing stable version.
As for source control, you should definitely use that as well if you're not already doing it. It would, among other things, allow you to go back and hotfix the stable version with minor bugfixes while still doing major rewrites of the software, as well as the features others here have mentioned, full history of your project, "unlimited" undo, etc.
I'm not sure what you mean that Visual Studio saves the code when you modify it. It does by default save when you build, but I don't think it saves while you're typing.
Anyway, what you're looking for is called a source control system.
You can try Team Foundation Service from Microsoft.
It works fine and you can share youre project whit colleagues.
http://tfs.visualstudio.com/
EDIT:
This is a free of charge option you can use, until you want to share youre project with more than 4 persons!! than you have to pay for TFS
You need source control.
If your project is open source you can use codeplex, it's an open-source Website where engineers and computer scientists share projects and ideas. Its features include wiki pages, source control based on Mercurial, Team Foundation Server or Subversion (also powered by TFS), Git,discussion forums, issue tracking, project tagging, RSS support, statistics, and releases
If you don't want to share your code you can use Team Foundation Server

how to manage Project in c# , ASP.NET MVC when i have a new copies and have something feature in it?

i have a project where i do something i have same copy from another who have do something in it later i have a thing to do currently.
so that's three copy and i am unsure that i am not confused with it. sometime i call wrong copy for finding the thing i want from them.
without using any software outside our office window any trick to manage all project or how i can manage them and make them one copy.
the same problem with some other problem come with when the same script used in two software , website who are used same script with have a small difference in both.
so i want to know how exactly all other manage them. i want to have a answer with .net plateform.
There are several source control solutions that have plugins to integrate directly with Visual Studio. I would recommend looking into Subversion. Currently at my office we use Vault, but it has some short comings, especially when it comes to renaming or moving a file and then editing it prior to a check in.
http://ankhsvn.open.collab.net/
http://www.sourcegear.com/vault/
I recently started a small pet project. It's written in C# with ASP.NET MVC3. As it's grown, my needs for source control also has grown. Here's what I've done:
Day one, I placed my project in a Dropbox folder. That way, I could reach my project files from all my computers (and even my iPhone).
A few weeks later, when I first had to make some serious changes and neede a fallback, I created a Mercurial repository in my Dropbox folder and commited all my code. I've got a blogpost on that here: http://csharptutorial.blogspot.com/2011/06/using-dropbox-with-mercurial.html. Mercurial is a great versioning system, because it doesn't require a server installation and your repository is copied in full to all locations where it's checked out.
Now, I'm looking at moving my project over to BitBucket (http://bitbucket.org/) where you also share and discuss code with others.
A good alternative to Mercurial is Git, using github.com in stead of bitbucket.org. Both have a learning curve, but they both represent modern version control tools and is well worth having a look at.
Source control and discipline.
You need to get an approach and method for managing your source. A source control system is essential for this. I use SVN and Ankh, as does Clayton.
However, you need an approach for using this. I always have branches. You can have development branches and merge these changes into a release branch when your code has passed all the tests. This way takes a discipline and time, but you need to do this to build quality into your system.

Best practices for large solutions in Visual Studio (2008) [closed]

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, visit the help center for guidance.
Closed 9 years ago.
We have a solution with around 100+ projects, most of them C#. Naturally, it takes a long time to both open and build, so I am looking for best practices for such beasts. Along the lines of questions I am hoping to get answers to, are:
how do you best handle references between projects
should "copy local" be on or off?
should every project build to its own folder, or should they all build to the same output folder(they are all part of the same application)
Are solutions' folders a good way of organizing stuff?
I know that splitting the solution up into multiple smaller solutions is an option, but that comes with its own set of refactoring and building headaches, so perhaps we can save that for a separate thread :-)
You might be interested in these two MSBuild articles that I have written.
MSBuild: Best Practices For Creating Reliable Builds, Part 1
MSBuild: Best Practices For Creating Reliable Builds, Part 2
Specificially in Part 2 there is a section Building large source trees that you might want to take a look at.
To briefly answer your questions here though:
CopyLocal? For sure turn this off
Build to one or many output folders? Build to one output folder
Solution folders? This is a matter of taste.
Sayed Ibrahim Hashimi
My Book: Inside the Microsoft Build Engine : Using MSBuild and Team Foundation Build
+1 for sparing use of solution folders to help organise stuff.
+1 for project building to its own folder. We initially tried a common output folder and this can lead to subtle and painful to find out-of-date references.
FWIW, we use project references for solutions, and although nuget is probably a better choice these days, have found svn:externals to work well for both 3rd party and (framework type) in-house assemblies. Just get into the habit of using a specific revision number instead of HEAD when referencing svn:externals (guilty as charged:)
Unload projects you don't use often, and buy a SSD. A SSD doesn't improve compile time, but Visual Studio becomes twice faster to open/close/build.
We have a similar problem as we have 109 separate projects to deal with. To answer the original questions based on our experiences:
1. How do you best handle references between projects
We use the 'add reference' context menu option. If 'project' is selected, then the dependency is added to our single, global solution file by default.
2. Should "copy local" be on or off?
Off in our experience. The extra copying just adds to the build times.
3. Should every project build to its own folder, or should they all build to the same output folder(they are all part of the same application)
All of our output is put in a single folder called 'bin'. The idea being that this folder is the same as when the software is deployed. This helps prevents issues that occur when the developer setup is different from the deployment setup.
4. Are solutions folders a good way of organizing stuff?
No in our experience. One person's folder structure is another's nightmare. Deeply nested folders just increase the time it takes to find anything. We have a completely flat structure but name our project files, assemblies and namespaces the same.
Our way of structuring projects relies on a single solution file. Building this takes a long time, even if the projects themselves have not changed. To help with this, we usually create another 'current working set' solution file. Any projects that we are working on get added in to this. Build times are vastly improved, although one problem we have seen is that Intellisense fails for types defined in projects that are not in the current set.
A partial example of our solution layout:
\bin
OurStuff.SLN
OurStuff.App.Administrator
OurStuff.App.Common
OurStuff.App.Installer.Database
OurStuff.App.MediaPlayer
OurStuff.App.Operator
OurStuff.App.Service.Gateway
OurStuff.App.Service.CollectionStation
OurStuff.App.ServiceLocalLauncher
OurStuff.App.StackTester
OurStuff.Auditing
OurStuff.Data
OurStuff.Database
OurStuff.Database.Constants
OurStuff.Database.ObjectModel
OurStuff.Device
OurStuff.Device.Messaging
OurStuff.Diagnostics
...
[etc]
We work on a similar large project here. Solution folders has proved to be a good way of organising things, and we tend to just leave copy local set to true. Each project builds to its own folder, and then we know for each deployable project in there we have the correct subset of the binaries in place.
As for the time opening and time building, that's going to be hard to fix without breaking into smaller solutions. You could investigate parallelising the build (google "Parallel MS Build" for a way of doing this and integrating into the UI) to improve speed here. Also, look at the design and see if refactoring some of your projects to result in fewer overall might help.
In terms of easing the building pain, you can use the "Configuration Manager..." option for builds to enable or disable building of specific projects. You can have a "Project [n] Build" that could exclude certain projects and use that when you're targeting specific projects.
As far as the 100+ projects goes, I know you don't want to get hammered in this question about the benefits of cutting down your solution size, but I think you have no other option when it comes to speeding up load time (and memory usage) of devenv.
What I typically do with this depends a bit on how the "debug" process actually happens. Typically though I do NOT set copy local to be true. I setup the build directory for each project to output everything to the desired end point.
Therefore after each build I have a populated folder with all dll's and any windows/web application and all items are in the proper location. Copy local wasn't needed since the dll's end up in the right place in the end.
Note
The above works for my solutions, which typically are web applications and I have not experienced any issues with references, but it might be possible!
We have a similar issue. We solve it using smaller solutions. We have a master solution that opens everything. But perf. on that is bad. So, we segment up smaller solutions by developer type. So, DB developers have a solution that loads the projects they care about, service developers and UI developers the same thing. It's rare when somebody has to open up the whole solution to get what they need done on a day to day basis. It's not a panacea -- it has it's upsides and downsides. See "multi-solution model" in this article (ignore the part about using VSS :)
I think with solutions this large the best practice should be to break them up. You can think of the "solution" as a place to bring together the necessary projects and perhaps other pieces to work on a solution to a problem. By breaking the 100+ projects into multiple solutions specialized to developing solutions for only a part of the overall problem you can deal with less at a given time there by speeding your interactions with the required projects and simplifying the problem domain.
Each solution would produce the output which it is responsible for. This output should have version information which can be set in an automated process. When the output is stable you can updated the references in dependent projects and solutions with the latest internal distribution. If you still want to step into the code and access the source you can actually do this with the Microsoft symbol server which Visual Studio can use to allow you to step into referenced assemblies and even fetch the source code.
Simultaneous development can be done by specifying interfaces upfront and mocking out the assemblies under development while you are waiting for dependencies that are not complete but you wish to develop against.
I find this to be a best practice because there is no limit to how complex the overall effort can get when you break down it down physically in this manner. Putting all the projects into a single solution will eventually hit an upper limit.
Hope this information helps.
We have about 60+ projects and we don't use solution files. We have a mix of C# and VB.Net projects. The performance was always an issue. We don't work on all the projects at the same time. Each developer creates their own solution files based on the projects they're working on. The solution files doesn't get checked into our source control.
All Class library projects would build to a CommonBin folder at the root of the source directory. Executable / Web Projects build to their individual folder.
We don't use project references, instead file based reference from the CommonBin folder. I wrote a custom MSBuild Task that would inspect the projects and determine the build order.
We have been using this for few years now and have no complaints.
It all has to do with your definition and view on what a solution and a project are. In my mind a solution is just that, a logical grouping of projects that solve a very specific requirement. We develop a large Intranet application. Each application within that Intranet has it's own solution, which may also contain projects for exes or windows services. And then we have a centralized framework with things like base classes and helpers and httphandlers/httpmodules. The base framework is fairly large and is used by all applications. By splitting up the many solutions in this way you reduce the amount of projects required by a solution, as most of them have nothing to do with one another.
Having that many projects in a solution is just bad design. There should be no reason to have that many projects under a solution. The other problem I see is with project references, they can really screw you up eventually, especially if you ever want to split up your solution into smaller ones.
My advice is to do this and develop a centralized framework (your own implementation of Enterprise Library if you will). You can either GAC it to share or you can directly reference the file location so that you have a central store. You could use the same tactic for centralized business objects as well.
If you want to directly reference the DLL you will want to reference it in your project with copy local false (somewhere like c:\mycompany\bin\mycompany.dll). A runtime you will need to add some settings to your app.config or web.config to make it reference a file not in the GAC or runtime bin. In all actuality it doesn't matter if it's copy local or not, or if the dll ends up in the bin or is even in the GAC, because the config will override both of those. I think it is bad practice to copy local and have a messy system. You will most likely have to copy local temporarily if you need to debug into one of those assemblies though.
You can read my article on how to use a DLL globally without the GAC. I really dislike the GAC mostly because it prevents xcopy deployment and does not trigger an autorestart on applications.
http://nbaked.wordpress.com/2010/03/28/gac-alternative/
Set CopyLocal=false will reduce build time, but can cause different issues during deployment time.
There are many scenarios, when you need to have Copy Local’ left to True, e.g.
Top-level projects,
Second-level dependencies,
DLLs called by reflection.
My experience with setting CopyLocal=false wasn't successful. See summary of pro and cons in my blog post "Do NOT Change "Copy Local” project references to false, unless understand subsequences."
