What is the doc issue?

Describe the issue
It looks like the documentation contains an invalid example, it doesn't compile for me with the latest nuget package
<PackageReference Include="AutoGen.LMStudio" Version="0.2.3" />

What do you want to see in the doc?
I would like to see a valid example of connecting to the LMStudio API endpoint and communication with chats.
