CommunityToolkit, ObservableProperty and Refactoring: Extract Interface?

[mikeKuester]

Hello together,

I use the refactoring option "Extract Interface" very often in Visual Studio, but is doesn't work for me since month now. I opened an issue in the roslyn project: dotnet/roslyn#68748 but since 10 month there is no comment or a like from another user. So I'm wondering now, that maybe no one else has this problem?

Visual Studio shows the following error:

"ExtractInterfaceCodeRefactoringProvider encountered an error and has been disabled."

System.InvalidOperationException : Operation is not valid due to the current state of the object.

Could you use the refactoring "extract interface" if you use the ObservableProperty?

I have the same problem. It is not fixed yet as far as I am aware.
