EDIT: Adding context to this issue:

It looks like the source generator in MAUI Community Toolkit is causing slowdowns with Roslyn.

TextColorToGenerator

The suggestion is to move to using ForAttributeWithMetadataName to create the analyzer which would mean creating an attribute and decorating any types you want the generator to run on with it.

This may reduce the usefulness of the generator towards the original goal, but I think short of making this change, perhaps we need to consider removing the generator, or otherwise making it opt-in somehow via msbuild property or something else.

[severity:It's more difficult to complete my work]
Working in MAUI projects within Visual Studio is extremely slow.
It already occurred in 17.3.* but even after upgrading to 17.4 I can wait ~ 10 seconds before code completoin or INtelliSense kick in.
Adding missing using-statements take up minutes now!

This does not happen in Console appplications, Xamarin projects, etc., only in MAUI solutions.
