Answer 1

It turns out that the C++ code was also associated with .NET for some reason. I used this article to help me change the c++ .NET version from 4.0 to 3.5. The basic steps are

1. Open the c++ project vcxproj in a text editor
2. Find v4.0
   • This may need to be created under the Globals PropertyGroup
3. Change 4.0 to 3.5
4. Open the project in VS
5. Right click the c++ project and select properties
6. Select Common Properties and confirm that the version is 3.5
7. Select Configuration Properties -> General
8. Make sure the Platform Toolset is set to v90
