Source Generator generated code cannot be compiled

[CyrusNajmabadi]

but if the entity is from the other reference item, it prompts an exception

What exception do you get?

[zy97]

@CyrusNajmabadi no exception,Code can also be generated，but the project cannot be compiled,prompt not to find a suitable way to rewrite

You said: > but if the entity is from the other reference item, it prompts an exception

[zy97]

@CyrusNajmabadi yes, but the code has also been generated,project cannot be compiled,this is demo

[CyrusNajmabadi]

@CyrusNajmabadi yes,

Ok. So what is the exception you get?

Can you clarify what you mean by 'it prompts an exception'?

[zy97]

@CyrusNajmabadi yes,

Ok. So what is the exception you get?

Can you clarify what you mean by 'it prompts an exception'?

The code generated by the source generator inherits a class, I implemented it manually, but the compiler says that the method cannot be found and cannot be overridden.

@CyrusNajmabadi I may not be describing it very well, but the phenomenon I'm seeing is that I can't find the method rewrite, even though I've manually rewritten the method

[zy97]

@CyrusNajmabadi That's the exception

In that screenshot I see warning CS8785 which says your source generator is crashing with NullReferenceException - hence it is not generating any sources during the build.

@jjonescz thx, I thought the exception didn't matter because the source code was already generated. When I fixed this exception, everything was sideways normal. But I never know why, the generated code is complete, but the compilation reports an error.
