I'm developping with visual studio 2008 and I use several project library used by several application project. There is also external dependency.
When I distribute the program, all the DLL appears in the program files folder which would make very easy to hack my program.
Is is possible to bundle all the project library into one exec file?
Well, if you sign your assemblies it will be near impossible to "hack" your program. Read about signing assemblies here. There is a program called ILMerge that you can use to bundle your assemblies into one, but I don't see the need really... at least not to avoid that someone hacks your codez :-)
Yes, there is. There is a tool called ILMerge. For more info see http://blogs.msdn.com/brad_mccabe/archive/2005/08/19/453703.aspx

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.
ClickOnce Deployement
I have made a C# class library, which uses other dll's made by others in the company, for COM interop. It is being used with MS Excel 2013 and works fine on my development machine.
To test it on other machines, i have copied the output (dll's and .tlb file) to my system 32 folder. I have then registered the dll's using regasm (using the /codebase argument). Finally, i added the reference to the .tlb in the Excel VBA editor. Allthough it is a little tedious with 6 dll's, the regasm works fine.
The next step is to distribute the Excel sheet to relevant users in the company, where most are located in different parts of the world in different deparments. This means i do not know what programs that are installed that are needed(for example .net 4.5). Also, since most people in the company know little about the command line, using the above procedure is not only a little tedious, but scares people. I therefore would like to make an installer.
Since i use VS2013, i have installed a plug in that allows me to make a setup file.
I have found this question, which is almost the same as mine, but i don't need the GAC part. How do i modify the procedure to my needs? - i have tried to follow the procedure given, but i get an error stating one of the dll's i use in my own, does not have a strong name and cannot be in the GAC. Build therefore fails. How do i rectify the above? - do i need to fix the dll or can i do this without the GAC-part?
How do i automate the installation process of my dll(s)? - The alternative right now is to roll out VS2013 to the users and make them run the project and register that way (Does VS express suffice?).
Thanks in advance - i started this project with little experience, so learning curve is a bit steep.
It's not clear to me exactly what you want to do, but that link does tell you how to register Dlls - just look at the properties of each Dll and set the register property. You can also add your tlb file to your setup, and mark that to be registered too. If that isn't what you're trying to do then edit the question.
p.s. Don't put tham in the system folder - pout them in your company's/app's common files folder.
In VS, I've only tested code and debugged it, but never actually prepared anything for a finalized program or release. Some of the programs I've downloaded have had dlls that need to be in the folder they're in, and I've had programs that come as just one .exe. Is there a way to compile all the files into one application and not have external dlls? Is this bad programming practice for some reason? How do I compile my VS program into one executable file?
I know this is quite an obvious question, which is why I can't really find an answer, because it would be too obvious to write any kind of tutorial on it.
With a managed language like C# or VB.NET, ILMerge is a utility that you can use.
ILMerge is a utility for merging multiple .NET assemblies into a single .NET assembly. It works on executables and DLLs alike and comes with several options for controlling the processing and format of the output.
If the question is just around getting VisualStudio to build executable programs, it does it every time you run them within it. If you are using all of the default settings, open your project folder and look for a /bin directory. Underneath it, there is a /debug and a /release directory. If you build your program in debug mode, look in the /debug directory, if you build it in release mode, look in the release directory. VS will put everything that your program needs within that directory. You can copy all of those files to another machine that has the .Net runtime installed and it should run.
If the question is more about combining multiple dlls into a single exe, actually, there is a tutorial on it at CodePlex:
As you know, traditional linking of object code is no longer necessary
in .NET. A .NET program will usually consist of multiple parts. A
typical .NET application consists of an executable assembly, a few
assemblies in the program directory, and a few assemblies in the
global assembly cache. When the program is run, the runtime combines
all these parts to a program. Linking at compile time is no longer
necessary.
But sometimes, it is nevertheless useful to combine all parts a
program needs to execute into a single assembly. For example, you
might want to simplify the deployment of your application by combining
the program, all required libraries, and all resources, into a single
.exe file.
http://www.codeproject.com/KB/dotnet/mergingassemblies.aspx
Lastly, if the question is about building an installer for broad distribution, Jan Willem B has a sample for WIX: Using WIX to create an installer: quickstart tutorial
Yes, you can use ILMerge for embedding managed .Net DLLs! Example here.
I develop application in C# with MSVC 2010 Express, with Forms/WPF/etc.
Application consist of some private assemblies (maybe DLLs) and .exe file. It uses .NET 4 features.
How I deploy this application to other computers? Of course if they have .NET 4 I just can send zip of .exe with .dlls and it work. But if they don't have .NET at all (on Win XP machine)? Or maybe they have lower version of .NET? Should I point them to install .NET from internet or package it with my app or what?
Thanks
There is click-once deploy from microsoft. It automates most of the tasks, including making sure you have the right .Net version and updating the app if a new version of your app is available.
You should create a installer package. If you are using the express versions of visual studio, you can use some free tools for this like WiX or Inno Setup. WiX is perhaps a difficult option to start with, but has a lot of flexibility. There are tutorials and example projects to modify to adapt them to your needs.
http://www.tramontana.co.hu/wix/
This tools create installers that can check if a certain version of the .NET framework is installed on the user computer, among other conditions. You can also include the .NET redistributable in your package, or point the user to download and install it.
We try to keep deployment as simple as possible, and one of the things we do is to ensure our application is just a single executable, no support files needed.
We several steps to get there:
Make sure all dependent resource files are stored in embedded resources where possible, and not on disk
Use ILmerge to link all assemblies into a single executable
Optional - obfuscate the assembly
Optional - If some parts cannot be ILMerged or obfuscated, forcing us to have multiple files, we use Xenocode's PostBuild to link all files into a single executable. Xenocode offers a virtual filesystem to do this. This also allows framework embedding so your app will run on a clean Windows install - no dependencies need to be installed :-)
Wrap the single executable into an msi installer using WiX
Wrap the single executable into click once deployment. For this we also use a little stub launcher executable which starts the main application, allowing us to reuse the same main application executable
Create a zip file of just the single file executable for manual installation.
We the following on our downloads site:
the MSI installer - we prefer people to use this one
A zip file with the Xenocoded (single file) executable
A zip file with the Xenocoded (single file) executable including the .NET Framework

Yes, you should point them to install .NET. Otherwise it won't be possible for them to run your application.
You didn't say what type of clients they are (are you making a small app for your friends to use or are they paying customers), but whatever the case may be, I'm always completely against sending a zip file with an instruction document describing what to do with it and what folder to extract it to. As Remy said, ClickOnce is not a bad idea, but I've found it to be a bit of a pain to set up (once you get it set up, though, it works just fine). On the other hand, a Deployment project is simpler and if I were you, that would be the first thing I'd explore.
Use xenocode here

No need to install anything.
It converts your exe to Native code indirectly and you can run anywhere on windows system.
It also has some option of adding framework inside and the total exe size will be somewhere arround 10MB + Your application exe size..
Thanks
yes! you have to give some general instruction about prerequisites to run your software and in that you can mention the Framework version 3.5 or 4.0 and other utilities you require.
please refer this document for Choosing a Deployment Strategy in Visual studio 2010 may this can help you
http://msdn.microsoft.com/en-us/library/e2444w33.aspx
when you package you application,you shoud include the .NET Framework
Check out Inno : http://www.jrsoftware.org/isinfo.php
It's free and pretty simple.
OTOH I've seen QTTabBar using it in its' codebase and it was literally one single text file (setup.iss). Let me see if I can find URL to their SourceForge page so you can see the source and the build ... There is it http://qttabbar.svn.sourceforge.net/viewvc/qttabbar/trunk/Install/ If you grab the source tree you can probably re-fit it for your app in a day.
I've created a basic console app in Visual Studio 2008, which references an external assembly.
When I publish and install the project, both the executable and the external assembly are installed in the target folder.
Is it possible to compile the project, and have all referenced assemblies included in the main executable - so there is only one file to distribute?
Thanks for any help,
Franko
You can use ILMerge to merge the assemblies for deployment. This lets you keep them separate during development, but put them all into one .exe file when you ship.
You can use ILMerge from Microsoft for this, or the Cecil tool from the Mono project.
You can create a setup file. so you can redistribute only one file.
But it still going to be installed into a folder with each assembly separated.
You can also consider placing your assemblies into the GAC.
If you find ILMerge is not enough because your app needs files other than .net assemblies, I have found that packaging it as self extracting exe using MakeSFX works nicely. It sounds unlikely but with correct command line flags the self extracting bit is completely transparent and it runs just like any other application.
