.NET: [Bug]: Debugger visualizer for AIAgent throws an error

[marcominerva]

Description

I have added an AIAgent to the HostBuilder:

builder.Services.AddAIAgent("Default", "You are a helpful assistant");

When I enter debug mode and hover the mouse over an AIAgent variable, the Debugger visualizer for the AIAgent class shows the error CS0103: The name 'DisplayName' does not exist in the current context:
