Re-enable and fix msbuild warnings #495
Description
Wait for v4 branch to merge before starting on this.
Due to thousands of msbuild warnings, several msbuild warnings are muted.
The most prominent ones are due to missing XML documentation on public types and methods.
We should address this warning and the others that are currently disabled, but right now working on v4 branch it just gets in the way.
At least these, but check the other .csproj files too:
