So I have this C# project that requires the use of some functions from a vc++ library. This vc++ library is then dependent on other vc++ libraries.
So in order to get this working, I created a c++/cli dll project that wrapped the main vc++ library. In the project linker settings, I just added the target vc++ library in the input field, and this resolved linker errors. I then added a reference to the cli project to the c# project references.
Everything compiled fine, but when I ran the C# project, there was a File.IO.Exception saying that the cli dll couldn't be loaded. After some tinkering around, I found that this error was happening because the wrapped vc++ dll dependencies could not be loaded. So I copied the vc++ dll into the same folder as the c# exe. I also had to copy all of the other vc++ dlls that the initial dll depended on.
Having to keep track of all of the VC++ dlls is burdensome, so I'm wondering if it is possible to statically link all of the VC++ dlls into the C++/CLI dll, so I do not have to copy them into the same folder as the C# exe. I tried adding all of the vc++ dependencies to the linker input field but that didn't do anything.
Thanks,
Alex

I'm writing a custom-action C# DLL that will be used from my WiX MSI installer. That DLL makes several pinvoke calls to another (unmanaged) DLL, which I need to include with my managed DLL (according to this post). I can do so by adding the unmanaged DLL to my C# project as a link from its compilation folder (from its C++ project in Visual Studio.)
The question is how do I add it depending on the bitness of the C# project and its type: x86 vs x64 and debug vs release?
For instance, when I build my custom-action C# DLL as x64, I need to include the 64-bit build of the unmanaged DLL. But when I build it as x86, I need a different version of the unmanaged DLL.
I have a C++/CLI project that has a dependency on a .dll file. I've set up a post build step to copy the .dll to $(OutDir), which works great when building the project.
Now, I have a C# project that references the C++/CLI project, but the .dll isn't copied to the C# $(OutDir).
There must be a way to just reference a C++ project without having to explicitly know about it's dependencies, right? It feels really icky to have to have my C# project directly reference into my C++/CLI project's dll folder. On top of that, it seems very error prone. I have two C# .exe projects that are referencing the C++/CLI project, so I (or a team member) have to remember to update the references to both C# projects if we end up with a new .dll reference in the C++ project...
Maybe some way during the C++/CLI project build to copy to the "parent" or "master" project output directory? I'm a C++ n00b and only somewhat familiar with the msbuild process, so any thoughts or solutions are welcome!
I have a dll created in VC++ and visual studio 2005 now i want to add same dll in my C# application and VS2010.
But whenever i tried it gives me erro
"a reference to "../name.dll"could not be added please make sure that the file is accessible and that it is a valid assembly or com component"
Seems like C++ dll is native dll (and not managed C++/CLI)
You need to look at P/Invoke.

I have a C# project (let's call it Driver) that uses an unmanaged DLL to interact with some hardware. I have another project that references Driver. When I build the project, the unmanaged DLL gets copied to the output directory as I want. However, when I publish the project as a ClickOnce application, the DLL does not get included in the application's files.
In the Application Files in project properties under Publish, I can see Driver's managed DLL, but the unmanaged DLL is not listed.
I'm certain there's an easy fix for this, but searches mostly lead to questions about including unmanaged DLLs in projects.
Thanks in advance,

After researching this some more, it seems that the solution is to add the DLL as an existing item in all the projects that use it. It seems, however, very clunky if you have multiple projects depending on it.
I have a python project that calls a c++ wrapper dll that calls a c# com interop dll.
In my computer, with all frameworks and programs installed, my project runs very well.
But in a computer that just got formatted it doesn't.
I allready installed c++ 2008 redistribute and the c++ part is working but when I call a function from it (that will call the c# correspondent one), it gives an error.
I want to know what are the dll dependencies from both c++ and c# dll's to see what is missing :)
Looks like you need Dependency Walker.
Dependency Walker (a.k.a. depends.exe) works for both native DLLs and managed DLLs.
It is included in some Visual Studio versions, and can also be downloaded here.
