Managed C++ with .NET Core 2.1

Question

We have a library written in C++. To make it more compatible with our more modern .NET projects, we wrapped this C++ library in another .NET project. It works fine when referenc

Answer 1

PInvoke seems to be the only way to go.

Put the library DLL in the solution folder (the actual C++ DLL, not a .NET wrapper).

NOTE: Don't reference the DLL in the solution, just place the DLL in the same folder.

Then use DLL Import to access the methods:

static class NativeMethods
{
    [DllImport("MyLibrary.dll", EntryPoint = "ValidateAdminUser", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
    public static extern Boolean ValidateAdminUser(String username, String password);
}

NOTE 2: It still requires the .NET Core project to run in x86 architecture.
