I presume the answer to be 'no', due to its C# support ending at version 9, and it not tokenizing interpolated strings.
If not, can I ask why not, or more specifically: are there any special problems I would encounter in implementing a Roslyn-based SyntaxLanguage?
I did the same for the old WinForms SyntaxEditor many years ago, and Roslyn's lack of a lexical tokenizing stage didn't play well with ActiPro's synchronous token-based syntax coloring system - I ended up with an inefficient system that converted the Roslyn syntax tree into a stream of fake tokens to make it work. However, it appears that the new WPF editor supports a pull-based approach for syntax coloring, without the use of tokens, and that an implementation of `TaggerBase<IClassificationTag>` can efficiently feed the editor with classifications directly from a Roslyn syntax tree.
Are there any other potential issues I should be aware of?
