RS2002 reported after updating to .NET SDK 6.0.200

Analyzer

Diagnostic ID: RS2002 (Rule '…' is part of the next unshipped analyzer release, but is not a supported diagnostic for any analyzer)

Describe the bug

After updating to .NET SDK 6.0.200, my project with a C# source generator is producing RS2002 errors. The same project builds when compiled with the previous .NET SDK version 6.0.102 so there seems to be some sort of regression introduced.

Steps To Reproduce

1. Install .NET SDK 6.2.200
2. Clone the repo at https://github.com/docopt/docopt.net
3. Checkout commit 09d814b987cc10d1de186a7a2ef33e90b9cef918 (the commit at time of reporting this issue)
4. Change the current working directory in your shell to the directory of the local clone
5. Run dotnet build

The above steps can be exercised with the following Docker command-line:

docker run --rm --entrypoint bash mcr.microsoft.com/dotnet/sdk:6.0.200 -c 'git clone https://github.com/docopt/docopt.net.git && cd docopt.net && git checkout 09d814b && dotnet build'

Expected behavior

Expected the build to succeed for all target frameworks when using .NET SDK 6.0.200.

Actual behavior

The following errors are emitted:

CSC : error RS2002: Rule 'DCPT0001' is part of the next unshipped analyzer release, but is not a supported diagnostic for any analyzer [/docopt.net/src/DocoptNet/DocoptNet.csproj]
CSC : error RS2002: Rule 'DCPT0002' is part of the next unshipped analyzer release, but is not a supported diagnostic for any analyzer [/docopt.net/src/DocoptNet/DocoptNet.csproj]
CSC : error RS2002: Rule 'DCPT0001' is part of the next unshipped analyzer release, but is not a supported diagnostic for any analyzer [/docopt.net/src/DocoptNet/DocoptNet.csproj]
CSC : error RS2002: Rule 'DCPT0002' is part of the next unshipped analyzer release, but is not a supported diagnostic for any analyzer [/docopt.net/src/DocoptNet/DocoptNet.csproj]

Additional context

When using the previous version of the SDK (6.0.102), the build succeeds for the exact same commit:

docker run --rm --entrypoint bash mcr.microsoft.com/dotnet/sdk:6.0.102 -c 'git clone https://github.com/docopt/docopt.net.git && cd docopt.net && git checkout 09d814b && dotnet build'

If I delete the AnalyzerReleases.*.md files then the build succeeds too.

@atifaziz This is a known issue currently. You'll have to avoid target-typed new for the DiagnosticDescriptor to get this fixed.
