Conflicting generated source file name

[AndreuCodina]

What source file name can I use? Currently I use

$"{namespace}.{className}.g.cs"

But for example, I have the folder Services with two files:

Service1.cs

public partial class Service1<T>
{
  [Exception]
  partial class MyException : Exception;
}

Service2.cs

public partial class Service2<T>
{
  [Exception]
  partial class MyException : Exception;
}

Each file has a subclass called MyException, and the generated file name is the same for both.

how about Service1.MyException.cs and Service2.MyException.cs?
