CAERIUS002 — Type must be partial
Severity: Error Category: CaeriusNet.Generator Applies to: [GenerateDto], [GenerateTvp]
Cause
A type decorated with [GenerateDto] or [GenerateTvp] is not declared partial, so the source generator cannot extend it with the generated mapper.
How to fix
Add the partial modifier:
csharp
[GenerateDto]
public sealed partial record FooDto(int Id, string Name);
