I used C# to write a program in .NET Framework 3.5.
But when I finished that and moved it to another computer on which .NET Framework 3.5 was installed, the program couldn't be started. It missed some dependent DLL files.
But when I moved this program to a computer that had Visual Studio 2008 installed, it ran perfectly.
So what can I do to export all the dependent DLL files automatically? So my program can run on a computer without installing Visual Studio 2008?
Actually you just need to include the third party component that your project use.
Edit:
To know them you need go to references and check the Added DLL.
Edit2:
Did you try to make a setup for your project it will automatically collect all the library used in your applications?
another point is, are you using win32 libraries, if yes also you should include them?

I'm currently working in VS2017 on a solution with multiple C# and C++ projects.
The installer project has the C++ redistributable as a prerequisite, with the option to download it from the component vendor's site.
Some of the clients want to be able to install the application without an internet connection.
The normal thing would be to put the package in the bootstraper and check the download from the same location as my application; the problem is every time Microsoft updates something with this library, compiling the application would work, but installation will have the old redistributable.
Is there any check to include Visual Studio libraries that are used when building the application, which ever version these may be?
I have a perfectly working windows forms C# .NET 4 application that uses a SQLite3 database file to store data and display forms.
When I deploy my app on any machine other then the dev machine, I get an exception thrown and it's message is "Could not load assembly System.Data.SQLite.dll or one of its dependencies. The specified module could not be found."
The System.Data.SQLite.dll reference in the project is set to Copy Local = True. Also, I tried manually loading the assembly with Assembly.LoadFile. The dll is placed in the output directory. I also tried setting the platform target to Any CPU as well as x86, no difference. All machines I am working with are 32-bit. What is the issue here? Why is my application trying to load the assembly and can't find it?
Thanks!
I had the same problem after publishing my program to a separate computer. Installing Microsoft Visual C++ 2010 Redistributable Package (x86) on the separate computer fixed the problem.
Note: the separate computer already had Microsoft Visual C++ 2010 Redistributable Package (x64) installed, the x86 version was needed.
'System.Data.SQLite.dll" requires "msvcr100.dll" which is one of it's Dependencies. This will be available only if you installed latest "Microsoft Visual C++ Redistributable" or any other product which internally provides this.
For example, VS2010 will install C++ Redistributable by default. Thats the reason your application doesnot works in some machine but works in others.
You could try pasting the "msvcr100.dll" in your application bin folder and distribute if you dont want to install VC++ 2010 Redist in all the PC's.
Some of the System.Data.Sqlite.dll modules depend on the "Microsoft Visual C++ 2012 Redistributable Package" .
You can find required dependencies on the official download page : http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
The answers already given didn't solve my problem. I tried to deploy to a VMware server. The solution that did help where given here: http://sqlite.1065341.n5.nabble.com/System-Data-SQLite-Deployment-Mystery-td71752.html Two methods are described there.
When i install this sqlite-netFx45-setup-bundle-x86-2012-1.0.88.0.exe, my app is able to find the right dll.
The second method is to add the dll to de app.exe.config in the debug or release dir. If you edit this file directly, there is a change VC will overwrite the file.
My main problem was that i installed the sqlite package manually. I didn't use NuGet, because i'm behind a proxy. If you do use Nuget, the information in the app.exe.config will be provided automatically.
Using NuGet behind a proxy is described here: NuGet Behind Proxy
i created a windows application that uses system.xml and system.io libraries, it reads and writes into a specific file (in same directory).
after i am done, i run the .exe file and its perfectly fine BUT when i tried it on any other computer, it gives an error and doesn't work(doesn't even open).
i think that i should attach some library files such as the xml library ?
I tried publishing as installation file and it also doesn't work
i don't know and don't know how to do that, please help.
System.XML and System.IO are part of the .NET Framework. Check which .NET Framework version your solution is compiled for (in the project settings in Visual Studio). Default for Visual Studio 2015 is the .NET Framework 4.5.2, which is not installed by default on Windows 7! You need to install it for your application to work, but you don't need to copy any DLLs manually.

I created a C# application that uses a C++ dll and im trying to create an install package that will allow this to run on other computers whether they have VS or not, the problem is i don't know what C++ libraries i need to let it do this. When i run just the application on a blank virtual machine it says
" xxxx has encountered a problem and needs to close."
If i go and download visual studio 2008 express version and install it on the machine, the my program will run fine. problem is express is 85-185mb to download and 335mb up to 1.1gb to install on a machine, the program that is using it is only 33kb. huge overhead there...
if i install just the C++ redistributable from msdn site, it takes up 4mb, but it wont let me run my program.
what packages from C++ do i need to make this program run on a blanked computer?
That question can be tough to answer. If you have the source of the c++ dll you should be able to see its dependencies unless the person used a lot of com or load library calls. One of the best tools I used to get c++ depencany info was depends.exe. One thing to check if its your code is that you are not using debug version with dependencies on debug dll that I think are not in the redistributable.
caleb, I recommend you a program called Dependency Walker. It will show you all the dll dependencies you have. I'm sure there are much more of them for Windows but that's the one I've been using for quite a while and I like it. So you did right by downloading the redistributable package from the MS web site but your app probably depends on some other libraries. When I tried to build my installer long time ago using Visual Studio I remember it was a way to include a redistributable package in your installer or use side-by-side installation - depending whether the license agreement of your Visual Studio version allowed you to do that or not. Also you could include all the dll dependencies you have in the installer.
Hope that helps
The C++ runtime dlls you need are the ones provided with the compiler as redistributable package and exactly this one! Other redist packages won't necessary work because of the manifests embedded in the executables which require an exact version (checked by a hash value of the binaries in the side by side assembly directory C:\Windows\SxS)
So you are right with the redistributable but you need the one that was installed with the compiler not one from a best guess from the internet. The exact versions can be looked at in the manifest files (XML)
My program is written in C# NET 2.0,it's using external functions from a dll written in C++ using Microsoft Visual Studio 2008 SP1.
If I remove the dll from the directory the program is placed,the program crashes at the moment it should use the dll.That's normal.
But the users that are using my program get the same error at the same place without moving the dll.They all have C++ Redistributable 2008 from >here<
Does it happen because I made the program in .NET 2.0 instead of NET 3.5 or it happens ,because the redistributable should be an older version?
Edit:Note for me,the program runs fine.
>>new thread<<
Its most likely the wrong runtime. Make sure you are distributing the correct one. These will always work on your dev box because the runtimes are in the path. For testing software, I use a windows xp virtual machine. I set up the virtual machine as a completely fresh install, install the components I know that I need (.NET framework, etc.), then run my installer. You will run into a surprising number of setup issues doing this.
The C++ Redistributable that you linked to looks like it is from the original release of Visual Studio 2008. If that changes with SP1, I could see that causing the crash. Maybe there is an updated version of the redistributable that your users need to install?
There's preciously little information in your question about the actual crash which could mean any of many things. In my experience with mixing .NET and native C++, many issues can occur in the side-by-side (SxS), especially if the DLL and the .NET application were built with different versions of the compiler.
You probably need to reproduce this problem on a local machine to debug it.
Dependency Walker can be excellent for tracking down these sorts of problems. You can load a DLL into it and it will tell you if any of its dependencies are unavailable. Sometimes missing DLLs are not necessarily a problem (if you do not go down that code path), but it is so much better than guessing.
No difference in this context of using .NET 2.0 or 3.5.
Look in method where you link and export functions from C++ (if it unmanaged)
If external functions had written on managed C++, look into signing and version of dll's
