.Net: Support Function calling for Amazon Bedrock (Using Converse APIs)

Hi,

I was trying out Claude 3.7 Sonnet on Amazon Bedrock and function calling wasn't working, when it was working fine with Azure OpenAI. I then found this table that says it's not even on the list of things you're aware of. Do you know when you will support function calling for Amazon Bedrock? Or Anthropic, or Gemini for that matter?

TIA,

Tilman

Our current implementation of Bedrock doesn't have tool support for the specific Amazon's Bedrock Tool Converse pattern below:

This ticket covers this feature request.

Hey, thanks for turning this into an issue. And thanks for a great product! I just wanted to add that these days function/tool calling is essential for pretty much any AI app, and without it pictures like these:

and texts like these:

Semantic Kernel was designed to be future proof, easily connecting your code to the latest AI models evolving with the technology as it advances. When new models are released, you’ll simply swap them out without needing to rewrite your entire codebase.

are a bit of a lie, because you can't just swap out your model for a new one. I appreciate it's a lot of work and you can't support all models/hosts, but without the ability to swap models easily, you're losing a lot of the value proposition of Semantic Kernel.
