.Net: Bug: Prompty not using tools_choice and tools field from template configuration

[repne]

Describe the bug
Prompty doesn't use the tools_choice and tools array from the template configuration.

You can see here that the field FunctionChoiceBehavior of PromptExecutionSettings is never set.

Expected behavior
The field tools_choice should default to auto if not set and if tools array has any function in it.

Platform

• Language: C#
• Source: Microsoft.SemanticKernel.Prompty 1.32.0-alpha

Workaround
This is how I am loading Prompty files to get function calling to work, this is not the correct behaviour (as it should read the functions from the .prompty file, but it works for me:

var promptTemplateConfig = KernelFunctionPrompty.ToPromptTemplateConfig(promptyTemplate);

promptTemplateConfig
    .DefaultExecutionSettings!
    .FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(sp.GetServices<KernelPlugin>().SelectMany(x => x));

return KernelFunctionFactory.CreateFromPrompt(
    promptTemplateConfig,
    new AggregatorPromptTemplateFactory(new LiquidPromptTemplateFactory(), new HandlebarsPromptTemplateFactory()),
    null);
