InvalidOperationException("No service for type 'System.Collections.Generic.IEnumerable1[Microsoft.SemanticKernel.KernelPlugin] has been registered.

[HappyNomad]

I'm partially transitioning a project from only Semantic Kernel to using some Micorosoft.Extensions.AI (so that I can use the evals library). In doing so, I'm running into an blocking issue.

When I run this code:

var service = kernel.GetRequiredService<IChatCompletionService>().AsChatClient();
service = ChatClientBuilderChatClientExtensions.AsBuilder(service).UseFunctionInvocation().Build();
var settings = new ChatOptions
{
  Tools = kernel.Plugins.SelectMany<KernelPlugin, AITool>(p => p.AsAIFunctions()).ToList(),
  ToolMode = ChatToolMode.Auto
};
var result = await service.GetResponseAsync(chatHistory, settings);

Although the correct tool call is being "queued up" in the result's Role=Assistant message, the Role=tool message that follows it has a "Contents" property with this exception message:

InvalidOperationException("No service for type 'System.Collections.Generic.IEnumerable1[Microsoft.SemanticKernel.KernelPlugin] has been registered."

What am I doing wrong? Although I have no idea why it's searching for a KernelPlugin collection, I tried registering one using dependency injection but it didn't work.
