TypeGen: System.Guid & GENERIC ERROR: Object reference not set to an instance of an object.

After trying to apply some new model changes today, TypeGen was giving me the following errors. I’m not sure how to trace it down. Possibly related is that it still has a problem with System.Guid (first stack), but even after I overrode all those to TsType.String, TypeGen gave the second error.

(I know this is not much to go on, but I’m at wit’s end. If you want me to look for particular things in our update to debug this, I’ll certainly oblige.)

APPLICATION ERROR: Generated type must be either a C# class or enum. Error when generating type System.Guid
