Resolve/mute build warnings

[illiteratePhD]

I am running 2.58.9.0 and I am trying to resolve a couple of build warnings and so far I've had no luck and have not been able to find anything to help me on the DocFX doc page.

The first warning I'm facing is related to the fact that I am using StyleCop with a custom ruleset and for some reason this causes a MetadataCommand.ExtractMetadata warning with the comment "Could not find rule set file "***.ruleset". This ruleset is of course not relevant to generating the docs so I would like to just squash it somehow.

The second warning is related to the fact that my solution is a mixed C# - C++/CLI - C++ thing and when I build the doc for the C# project I get a warning saying "...because the file extension '.vcxproj' is not associated with a language.". The C++ stuff is an entirely internal thing and should not be documented anyway but I have not figured out how to ignore the C++ project.

I would really appreciate any pointers I could get!
