You need to run eng/scripts/CodeChecks.ps1 contentsafety to make sure everything is updated.

Actually, I see now why the build didn't fail like it should've: you need to add a package-level "samples" with markdown files that reference the snippets. See https://github.com/Azure/azure-sdk-for-net/blob/main/samples/README.MD.

Hi @heaths , I've added a package-level "samples", please check.
And I've also ran eng/scripts/CodeChecks.ps1 contentsafety locally, it's wired that it always report following error:

error : Missing project. Solution references a project which does not exist: D:\src\mengaims\azure-sdk-for-net\sdk\contentsafety\Azure.AI.ContentSafety\项目. [D:\src\mengaims\azure-sdk-for-net\sdk\contentsafety\Azure.AI.ContentSafety\Azure.AI.ContentSafety.sln]

Is it the same case from your side? I'm confused with these errors, since I've double checked there is no invalid project reference in this solution file, and the CI build all look good. Besides I tried to search for some information but did not find the description of this script in https://github.com/Azure/azure-sdk-for-net/blob/main/CONTRIBUTING.md.
So that I'd like to ignore them, are you ok with it? Could you help approve if no other concern?
