Hi, We are using the CSharpSyntaxLanguage provided and having similar code snippets shown below. We've then encountered an issue that squiggle display of errors appear on the line for the default. If I replace the throw exception part with some string value, it would then happy. I believe that syntax is part of C# 8.0, which should be fully supported by the SyntaxEditor, do I miss anything or maybe there's some extra setup required?

    int testBit;
    string result = testBit switch
        0 => "P",
        1 => "F",
        _ => throw new Exception()

Hi Luke,

You're absolutely correct about using a throw expression there. We were able to identify and fix the issue in the C# grammar for our next maintenance release. Thank you for reporting the issue and providing a clear example for how to reproduce it.
