Random crashes #45

The generator is randomly crashing with the error below:

Generator 'AutomaticInterfaceGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result.
Exception was of type 'ArgumentException' with message 'The hintName '<redacted>.IFileDiscovery.cs' of the added source file must be unique within a generator. (Parameter 'hintName')'.
System.ArgumentException: The hintName '<redacted>.IFileDiscovery.cs' of the added source file must be unique within a generator. (Parameter 'hintName')

I've encountered this Problem before. The problem is that the created name must be unique, but the API of an interface Generator does not allow to check for that. To solve this: Can you make sure that only one interface with the name FileDiscovery exists?

skarllot commented 4 months ago

Yes, there's only one

ChristianSauer commented 4 months ago

OK, can you produce a minimal sample?

I couldn't replay the problem anymore
