Description

Using StyleCop with rules Action="Error" produce unexpected compile errors from autogenerated code and used libraries
For example:
Using StyleCop.Analyzers.ruleset with:
<Rule Id="SA1505" Action="Error" />
Produces errors:

/Droid/obj/Debug/net6.0-android/generated/src/Java.Interop.__TypeRegistrations.cs(24,24): Error SA1505: An opening brace should not be followed by a blank line (SA1505)
/Droid/obj/Debug/net6.0-android/generated/src/Com.Android.Installreferrer.Commons.InstallReferrerCommons.cs(47,47): Error SA1505: An opening brace should not be followed by a blank line (SA1505)

StyleCop provide option with ignoring all errors and warnings using // <auto-generated/> comment. And I found one ticket that refers their logic to avoid generated code: DotNetAnalyzers/StyleCopAnalyzers#1430
Could we somehow add // <auto-generated/> comment for all generated code under obj/ folder?

Steps to Reproduce

1. Create any net6-android project
2. Add SonarCop with more rules (like SA1505, SA1507) as Error
3. Try to build

This has been fixed for .NET 8:
dotnet/java-interop#1052

Wonderful. Now other issue, that libraries like Mvvm Cross not supporting .net 8 😄
Is there any workaround?
