I tried to create a resource file to store the error message but couldn't get the associated C# file to look like an existing one, like the one in src\Security\Authentication\Core.

Hi there 👋

While the build failure seems unrelated to my changes, please let me know if you think they're linked.

Related to my initial message about Resources.Designer.cs files, can you let me know how they're generated? When I added a resource file through VS, it definitely didn't look like the existing ones in this repo:

• much larger comment about the fact they're autogenerated;
• FormatXXX methods were not generated either.

👋 @Tratcher @HaoK

Could you please let me know if there's something you want me to change in this PR?

Appreciate your time 🙏

@HaoK can you take this? You know the options validation.
