Hi @anandmeg

This looks good. I had a suggestion on one of the prompts to use that opportunity to teach customers about record types. Let me know what you think, and then I'll merge this.

Hi,

I came here from https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/how-to-initialize-a-dictionary-with-a-collection-initializer#use-ai-to-initialize-a-dictionary

Are we not concerned that:

• This kind of suggestions may clutter documentation and make it more difficult to find the answer?
• The AI agent that "learn" from the documentation may start to suggest to use AI-agents to help instead of helping?

Best regards,

Thank you for the feedback! This particular AI highlight is being removed in another PR. We're in the process of reviewing and revising these highlights to make sure they're as helpful as possible. We haven't encountered any issues with recursive answers so far; it's something that we're keeping an eye on.
