#61953 will change how this looks but we validate that compilable names are emitted here.

It can't start with a digit presumably?

I don't think there's a restriction on metadata names starting with digits per the CLR spec. However, since we derive this MetadataName that we pass to this method from a TypeSymbol resolve via static analysis, it's probably come from C# code where an identifier starting with a number is invalid.
If we do hit that case, I think emitting a method name starting with _ is OK syntax so the generator shouldn't emit invalid syntax.

Gonna merge this so it lands before the preview.5 cut-off. Happy to address feedback after merge in a follow-up PR. |
This pull request introduces several updates to the
ValidationsGeneratorin theMicrosoft.AspNetCore.Httpproject, focusing on improving type name sanitization.SanitizeTypeNamewith a compiledRegex(InvalidNameCharsRegex) for improved clarity and maintainability. (src/Http/Http.Extensions/gen/Microsoft.AspNetCore.Http.ValidationsGenerator/Emitters/ValidationsGenerator.Emitter.cs, [1] [2]Fixes #61388.
Note: I realize that as a follow-up to this change we need to make updates to the implementation to support validating dictionary values. Since that's a bit more involved I'll pull it out into a separate PR.
