Need to disable parallel_tool_calling in .net too

[kenvanhyning]

My team is working on a .net SK application and we want to use gpt-4o mini but we're seeing the 'string does not match pattern' error regularly with that model.
I saw at the end of the thread on this issue: #8292

that support for .net to disable parallel tool calling is coming soon. I didn't see any issue for it though. Any idea on when it will be available?

Hi @kenvanhyning, thanks for your question. The ability to toggle parallel_tool_calls in .Net is available. In the following .Net concept sample, it shows the various ways to configure function calling options:

semantic-kernel/dotnet/samples/Concepts/FunctionCalling/FunctionCalling.cs

Line 478 in 7579b24

public async Task RunNonStreamingChatCompletionApiWithParallelFunctionCallOptionAsync()

.

You'll want to do the following:

FunctionChoiceBehaviorOptions options = new() { AllowParallelCalls = false };

OpenAIPromptExecutionSettings settings = new() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(options: options) };

Great - thank you! I'll try this out now. Appreciate the quick response.
