/Common.props enables the .NET Analyzers and StyleCop, and imports BizHawk.Analyzer and some third-party Analyzers.

You can tell the assembly references are working if ;; is flagged with "MA0037: Remove empty statement". You can tell the ruleset reference is working if that was flagged but the output isn't flooded with other warnings, such as "MEN002: Line must be no longer than 160 characters". Similarly, you can tell the StyleCop config reference is working if the output isn't flooded with warnings such as "SA1600: Elements should be documented".

Important: /src/MainSlnCommon.props disables Analyzers unless -p:RunAnalyzersDuringBuild=true is passed to dotnet / the build script.
