i have an issue with the old setup projects in VS2010. please don't blame me for using that. it's a company decision which cannot be changed. poor enough i HAVE to deal with it.
i think it's quite usual what we got: a solution with some projects. the projects reference assemblies. some of them are 3rd party components. they are ALL referenced to/from the SAME individual folder (NOT the GAC or something like C:\Programs...). we just don't reference the installed versions. we want to keep them all in one place.
here comes the point... the project itself points to the folder we want. building and running is fine.
when i examine the setup project, SOME of the 3rd party assemblies are taken from our specific folder, others are taken from C:\Programs...
i just don't know why. i cannot influence this as it seems. even manually editing the .vdproj file ( were "GAC:FALSE" can be set) doesn't help! we need to reference the specific *.dlls in our folder.
has anyone an idea on this? i haven't found something so far...
cheers!

This is how VS behaves. Even though you told him to search for your 3rd party dlls in your own folder, if it finds the same dll in GAC, it will reference it from there. On computers that do not have the dll in the GAC, it will reference it from your folder. In other words, if the computer you deploy your application has all the 3rd party assemblies in the folder that you referenced them from, and the folder exists on the target machine, the application will not crash, even if the dlls are not in the destination you see on your own machine, and will use the assemblies from the folder.
Maybe somebody fiddled with the default reference paths in Visual Studio. If you look at this article, about half-way through it explains the registry keys that are used to locate referenced assemblies:
http://msdn.microsoft.com/en-us/library/wkze6zky(v=vs.100).aspx
I think that the VS search mechanism will go through this list at build time, and you may end up with a rather strange combination, especially if some assemblies have dependencies on others and the assembly versions are different. So if you start with a certain assembly that requires others with a particular version it will chase that list of directories until it finds them.
I don't believe it is correct that VS will get assemblies from the GAC by default for reference purposes. The .NET runtime will do this when you run the program, but at dev time all the MS assemblies, for example, are referenced from the SDK install, not from the GAC. The GAC is a repository for running programs that require those assemblies, not a reference for dev builds.

I'm new to c#, and i'm stunned by the amount of files that are generated by my release output.
I wrote a REALLY simple program that i want to distribute, no external assets or anything special.
but still, there are 10-15 files generated (.dlls, .pdbs, .configs, etc. etc.)
I did a little research yesterday and i got the impression that it is simply not possible to clean up this mess without a REALLY big hassle?
i tried Fody (didn't work at all) and Tidybin (or something like that?) (created a lib folder and put everything there, which was nice, but the program stopped working and threw errors about the missing files)
I'm looking for a way to generate a clean release version.
ideally with JUST my exe, with all the dlls and other stuff embedded, but everything i read about that was just way above my head and overly complicated (why isn't this super easy to do???)
if that's not possible, i'd be happy with moving everything except the .exe in a lib folder. but that didn't seem to work. how do i update the path inside my application, so that those files can still be found? like i said, that plugin seemed to do half the job, while leaving all links like they were.
(side note: why is there not ANY KIND of ducomentation for all of these plugins? i really don't have the SLIGHTEST idea what to do)
thanks
If you have a simple application, there shouldn't really be that much in the folder.
Actually, there should be:
1 exe, 1 pdb (only for debug build), 1 exe.config file for the application
1 exe, 1 pdb (only for debug build), 1 exe.config file for the Visual Studio Host Process
If there is the System.Net.Http library referenced, this could create a folder with many localizations. If you don't use it: Remove the reference.
Please note that you do not need to deploy all these files! If the application only references framework DLLs, all you need is the .exe and .exe.config file.
DLLs will not be embedded, but if they are framework libraries, they should not be added to the output folder unless you set the "Copy Local" property of the reference. And you don't need to deploy them along with your application, as obviously they are installed along with the .NET framework on the target system anyway.
If you reference any DLLs that do not belong to the .NET Framework, you normally deploy them along with your application. It's easiest to put them in the folder along with your application, but you can also put them in the global assembly cache on the target system.
There are solutions that package the executable, third party DLLs and stuff into an EXE wrapper that is unpacked every time you start the application, but I advise against this. The user won't expect this to happen, virus scanners may block this and builtin mechanisms like .NET settings may not work properly for those solutions.
The easiest way to distribute your code is using InstallShield Visual Studio edition. (That is available with your Visual Studio license)
Download and register, then add a new distribution project to your solution.
InstallShield Limited Edition for Visual Studio
A wizard will help you by selecting the main distribution files. And it is a useful tool distributing new releases of your application.
As a second option I use is ClickOnce (Microsoft), but for specific internal applications.

Following problem: we're using gated build with TFS 2012. As soon as the TFS starts the build, everything is just copied into one folder.
Our actual application is a Silverlight application.
Our unit tests though are put in .Net projects
One part of our application uses 3rd party controls. It uses a Silverlight assembly, which grants a certain functionality. The same functionality is given in a .Net assembly, which we use in a parallel project for server-side stuff and unit testing. It actually grants the same functionality (except the UI things). Both of those assemblies are referenced with "copy local = true".
If I build the solution locally (which contains both assemblies referenced in different projects), everything works fine. But as soon as I try to deploy it via TFS, the build fails because of a FileIOException or something. It tells me that the 3rd party assembly is not the proper file.
I think that occured, because when the TFS starts building, everything gets copied into one folder. Both: the .Net assembly and the Silverlight assembly. They both have the same file name. I think that's, what messes up the TFS build.
Do you have any suggestions for this problem? It's a requirement that we still have the "uber solution", which contains all the projects. So splitting up .Net and Silverlight projects isn't a solution.
It is probably due to when you are building through TFS or some Non-IDE builder you are somewhere having an output directory specified so its just collating all assemblies in one place, causing an issue.
You can either append a suffix to your silverlight project assemblies, which will just make the assembly output as "YourAssembly.silverlight.dll" rather than "YourAssembly.dll", it would not mess with namespaces internally, although this can be confusing to other people unfamiliar with your system, generally you would just use namespaces to split them out so your silverlight framework would be within a *.silverlight namespace which paired with your project name indicating the namespace difference would solve your problem.
I currently have one solution that references ten .dll files. Those .dll files in turn all reference a shared .dll file.
Today I started getting an error while debugging that stated, "The source file is different from when the module was built error.", immediately following a recompile of the shared .dll.
I tried all of the usual. I deleted bin and object folders. I recompiled. I closed all instances of Visual Studio and restarted after they were all closed. I restarted my machine. Nothing fixed seemed to fix it.
I'm guessing one of your 10 DLLs references a different copy of the shared DLL, and not the one you compiled.
Since you have all the sources, put all the projects in the same solution, and have the DLLs reference the shared DLL's project. This will solve your problem.
It has happened to me too. Once I fixed it by recompiling project-by-project from ground up (in the same order that VS does).
Another time this didn't help. I can't remember what I did then.
I believe it is a bug in VS.
I notice you are running VS2008. The problem might go away with an upgrade (the supposed bug might have been fixed). VS2010 is also nicer to work with than VS2008 so it could be areason of its own to stay current. Why not download an evaluation VS11 and try it there.
Move all projects to one solution, reference them in a simple and correct way. Compile. Now you have the right DLLs everywhere and can go back to your more diverse solution(s).
You can also try to use MSBuild. It is easy since you already have the projects in VS. Once it is build by MSBuild (which VS uses itself) it should probably compile in VS again.
Finally you can try to build with nAnt. Once it compiles you can probably compile in VS again.
Good luck. I've been there. It sucks.
I suppose you referencing in your project directly to some DLL, and not a project. Which means if you even cleanup and rebuild, the same dll will be used like a reference.
Very often this is a problem, so I suggesting you check your references.
[edit] Assumed this was asp.net, disregard. [/edit]
Have you deleted everything your temporary .NET folders?
Either in:
C:\Windows\Microsoft.NET\Framework[Your Version]\Temporary ASP.NET Files
or
C:\Windows\Microsoft.NET\Framework64[Your Version]\Temporary ASP.NET Files
When comparing last-modified dates of the shared .dll across output folders of all of the solutions with the file that was stored in the output folder of the primary solution, I noticed that they were not the same as the file that I had just built.
This didn't make sense to me, so I simply copied the new files into the output folder. This did NOT solve the problem. On subsequent builds, the old version was again placed into the output folder, immediately causing the error while debugging...
During compilation, an older version was being pulled along with one of the other referenced .dlls. There is obviously some sort of check that is made with the names of files pulled in so that only 1 file is used, but no check is made for latest version number.
I was able to actually solve the problem by creating a reference to the shared .dll from the primary solution. Direct references are obviously (or perhaps hopefully) pulled in before files that are referenced by references (and are already copied into the same output folder as those referenced .dlls), so the latest file was successfully pulled in first.
If clarity is needed, let me know!
I rarely respond to posts since I am generally too busy, but I just spent a ton of time on this same exact problem. I am running VS 2008 in Windows 7. I had set the my Visual Studio to run in XP Compatibility Mode to fix some issues I had with a different project and forgot to reset it to NOT run in compatibility mode.
Once I removed the Run In compatibility MODE (In Windows Explorer on the DevEnv.exe) my problem with the source being out of sync with the debug information went away.
Hopefully this might help someone in the future with the same problem.
I found posts mentioning issues with DEVPATH and webapps and I think MVC falls under this same band-wagon.
On my local PC; in one instance I need to be able to design and test our library of dlls; on another, I need to use these dlls, in various websites. Due to the number of sites we handle, we are looking at storing the dlls in the GAC in an attempt to avoid duplication.
When I want to work on the library I need to remove all the dlls from the GAC and then re-install them again once I have finished my development.
I have everything set as defined in various sources to make DEVPATH work, but it isnt working for me in my MVC project.
Is it possible to have dlls installed in the GAC, but run an MVC project that uses the DEVPATH copy.
I'm not having a lot of luck finding anything on the subject, but I am hoping it is possible.
Finally got a work around, it was quite obvious now I have done it.
It is a bit of work, but it does mean you can debug a website.
Also, it isn't using DEVPATH still, but it works so I am happy.
The main assumption I made was that the GAC always wins, even if you physically copy the dll to the bin the GAC will find the file first and use that reference.
So, the way I have found to work with local files (especially when I want to be debugging a website), is to change the assembly version number of the projects I reference to a new number. As this version doesn’t exist in the GAC, the Visual Studio webserver(cassini?) and iis web servers will use the local dlls. So any breakpoints I had added to my services etc. will then be picked up.
We are using TFS and VS 2010.
I have been working on a project that is using TFS as source control.
I have quite a few dlls that I have downloaded (such as log4net) and referenced in my project.
When a new programmer connected to TFS and got my project out of source control, it failed to build as it said it was missing all these referenced dlls.
What did I do wrong here? How can I include those referenced DLLs in source control.
Do I need to add all these dlls to my project before referencing them? when I referenced them, I just browsed to where they were on my file system.
I've found the best practice for 3rd party DLLs is to create a "Library" folder in your sln/proj file structure and copy all the necessary DLLs into this local folder for reference. You'll also want to make sure these DLLs are checked into source control. This way, everyone who works on the project gets the exact same versions of all DLLs, and the reference paths are exactly the same.
Referencing 3rd party libs in a arbitrary download or install location will be problematic, because it will require all developers to maintain the same download structure for all DLLs. Also, if everyone references DLLs outside of the project structure, it's harder to guarantee that everyone's on the same version.
The other option would be to have everyone install the DLLs into the GAC, but that can be a real pain too, especially with version management and deployment.
I created a "ThirdPartyDLL" folder in my project folder in which I copied all the extra DLLs into it. I then went into source explorer and added those DLLs into the team foundation server so I could be sure I'm using the correct versions of the DLLS for specific versions of my application (and so everyone else is on the exact same page as I am).
View - other windows - Source coontrol explorer
Right click project folder - add items to folder
You won't be able to select a specific folder with DLLs in it, but instead you can select the individual DLL files within the folder. You will then see the "ThirdPartyDLL" folder appear in that window.
Once this is done, those dlls are in the team foundation source control. Whenever a dev checks in, they will get the most current version of the DLLs.
Don't forget to remove the old references in your app and change them to your thirdpartydll folder.
I used to copy the DLLs into the bin folder but the issue I ran into was when the DLLs got upgraded. Initially when my project was small it wasn't a big deal. Now that I have multiple DLLs and applications that I created it became very difficult to maintain consistent versions of DLLs outside my project. My best example is the licensing dll I purchased. When this got upgraded all applications and libraries needed to be on the same version. If I forgot one then I had weird issues or the application just stopped working. Now that I have everything in one folder, I make the change once and everything is upgraded.
Hope this helps.
Andy's suggestion is a good one and I've used that in the past. At my current job, we have a "reference" folder on a network share for all of us to build from. We have a very fast network here, though and all developers are in a single office. This solution won't work as well if you have a lot of remote developers or a slow network.
I've tried various methods for dealing with this and have settled on dropping required dll's in the bin folder and making sure they are included in the project for source control. I've heard people say this might not be a good idea but nobody has provided good reasoning for it and it's worked well for me.
My second choice would be to carve out some space on a network share and organize the various 3rd party dll's there. You can put your files in folders with verion numbers to keep things straight and everyone should have access to everything they need, so long as everyone uses the normal network paths as a reference.
Adding a seperate folder within the project is also workable but seems messy, since you end up with extra files that you don't want included in your release.
