Make sure we are handling native DLLs correctly #86
Description
For example, LibGitSharp2 includes the native libgit2 DLL. We could use this as a test case.
Part of this will be making the NuGet package's automatic build file either handle things or fail if native DLLs are included (see issue #32 )
The other part is making sure we handle the DLLs correctly at compile time and runtime. I think we don't want them in the compile action, but we do definitely want them in the runfiles. See this comment for some more context.
