C# Gen variant contains tag method (Build fails because of two members named "Tag")

This wit file contains a variant which has a method called tag. The generated class has also a variable called "Tag" the compiler throws an error because two members have the same name. Because the Tag variable isn't part of the wit file and just a variable from the generator this needs to be fixed.

Expected behavior would be that the generator calls his own variable in ways that it doesn't effect the defined method/variable from the WIT definition.

Inizia individuando il codice del generatore C# che emette il membro Tag generato della variante, quindi riproduci il caso WIT in cui una variante definisce anche un metodo Tag. Verifica che la classe generata venga compilata e conservi il membro definito in WIT senza collisioni di nomi.
