Hi, your report should be posted here: https://github.com/dotnet/roslyn/issues because these exceptions are from Roslyn IDE analyzers not from Roslynator. Thanks.

Good news, bad news. First the good news, this is indeed fixed in Visual Studio 2019 (preview) 16.11.0 Preview 2.0. Now the bad news, it is broken in Visual Studio 2020 (Community preview) 17.0.0 Preview 1.1
