Implement IChatClient

• Implement IChatClient Implement IChatClient (Microsoft.Extensions.AI) #112
• Add Async-suffix to async methods Code style #81

You can use something like Enum.GetValues(p.ParameterType)

[SteveSandersonMS]

Or if you want to be more precise about it, it's possible to use p.Schema. If it's a JsonElement, it's telling you the JSON schema, so you could use that to read the set of possible values. That would be more technically correct since it would work regardless of AOT and trimming concerns. However if you want to start with Enum.GetValues(p.ParameterType) that would be a reasonable starting point.

[awaescher]

Thats a nice idea but where can I find how to handle it? What can I check for and what are the possible return values? Got me any resource or a way how to test it?

private static string ToFunctionTypeString(JsonObject? schema)
{
  return "string"; // TODO others supported?
}

I'll close the other comments aiming for the same change with this note that the JsonSchema approach would be good for these methods:

• GetPossibleValues()
• ToFunctionTypeString()

@awaescher This looks superb to me!

Important

Strongly suggest considering this change to be available in a feature-branch or be a pre-release package

Currently Semantic Kernel cannot have a dependency on .Net 9 features yet, if any updates after this merges into main we won't be able to update to your connector until it becomes GA, assume any other customers that also have a hard (.Net 8 LTS) configuration will be in a same position.

SK is also adding support for IChatClient clients in a feature branch waiting the right timing to be publicly available.

[SteveSandersonMS]

I'm not sure this is actually a problem. This change doesn't entail taking a dependency on .NET 9.

Microsoft.Extensions.AI.Abstractions is netstandard2.0 and is an out-of-band package - it's not part of the .NET 9 release. The only consequential dependency it involves is System.Text.Json, and that will be version 8, which (very soon) will be the oldest version that is still under support anyway.

[RogerBarret0]

@SteveSandersonMS Thanks for the added context, would like to follow more on that info on the System.Text.Json.

[awaescher]

You'll see this change as soon as the next preview version of the package is published (by default, this happens monthly).

Awesome. Can we get this earlier, so that I could merge and build 4.0?

@RogerBarreto: Semantic Kernel could stay at 3.x after your pull request #114 but should also be able update to 4.x right?

[awaescher]

Published another preview version 4.0.0-preview.9 containing the latest changes from this pull-request.

You are right, we will update to the 4.0 as soon this feature branch

microsoft/semantic-kernel#9183

Is merged in main

[awaescher]

I guess I'll build a 4.0 as soon as Microsoft.Extensions.AI.Abstractions uses System.Text.Json in version 8.0.5.

A new version is up on nuget.

[awaescher]

Awesome, thanks @stephentoub.
So we got 4.0 out 🎉
