How to import a c++ dll as a reference in c# UWP project?
0
I am trying to import a c++ dll in a C# UWP project.
Steps:
- Place the dll in the bin folder.
- Try to P/Invoke the dll using
DllImport. - System.Typeload Exception occurs telling to look in
build warnings
In the build warnings, I get a MCG0007: Unresolved P/Invoke Method warning. Calling this method would throw exception at runtime.

Does your dll have the function that you P/Invoke?

This warning can be generated when you build the Release version with .NET Native enabled. Simplest explanation is that you tested the Debug build but forgot to copy the DLL for the Release build.

@HansPassant I unchecked the option. I have placed the debug and release builds of the dll in their respective folder under bin/. It gives me a system.dllNotfoundException.
