UnrealBuildFiles.csproj

Browse Source 
Generate UnrealBuildFiles.csproj, a project that contains references to all of the Build.cs and Target.cs files in the solution, and add it to the generated solution.

With this project in the solution, Intellisense is available when editing these files, and the project may be compiled in Visual Studio, providing representative results of what UBT will do with the files (UBT will re-compile the files when it needs to)

Using Visual Studio 2019 16.9.6, adding this project increased memory usage by ~20MB after load (from 540MB to 560MB) for a workspace containing Engine, and two sample games.
