Customer Impact
Customer reported bug. Source generators are currently not value tuples with explicitly named elements properly, resulting in compile-time errors in the generated code. This can break source generation for any DTO containing value tuple properties (even if a
JsonIgnoreattribute has been applied by the user).Testing
Testing has been added to validate the broken scenario.
Risk
Low. Product code is a simple fix adding a missed clause in the field symbol filtering logic.
