The code generated by IIncrementalGenerator is inconsistent with the code participating in the compilation.Why?

[HarlingPI]

I want to use an incremental generator to automatically implement a ToString() method for classes/structs marked with [AutoToString]. However, the code generated by the generator is inconsistent with the code that actually participates in the compilation. Could you tell me why? The project is located at:https://github.com/HarlingPI/IncrementalGeneratorTest.git。

You'll need to start by defining "inconsistent".

The code generation logic is as follows:

1.Filter out class/struct declarations marked with [AutoString].
2.Scan all fields and their corresponding XML comments.
3.Automatically generate the ToString method for the classes/structs from step 1.
The logic for generating the ToString method is:
If a field comment is found, output "comment + field value".
If no comment is found, output "field name + field value".

However, the code generated by the generator is "comment + field value", while the runtime output is "field name + field value".

I'm confused. Why is the runtime behavior inconsistent with the code generated by the generator?

Well, being perfectly honest with you: it isn't. Looking at the repo you linked (it looks like you need to read through the cookbook for best practices), this is what you're generating:

but,in visual studio likes this.

You probably haven't turned on documentation comments in TestProject. https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-options/output#documentationfile
