.NET: Add Support for Passing Agent Name (String) Instead of AIAgent Instance to MapAGUI Method

[Varorbc]

It would be great to enhance this API by allowing MapAGUI to accept an agent's name (string) instead of requiring the actual AIAgent instance.

Lines 31 to 34 in 7e5de8f

	public static IEndpointConventionBuilder MapAGUI(
	this IEndpointRouteBuilder endpoints,
	[StringSyntax("route")] string pattern,
	AIAgent aiAgent)

Thanks @Varorbc, we'll take a look.

I also need this. Checkout #2343.

app.MapAGUI("/agents/{agentId}", async (context) =>
{
    var agentId = context.Request.RouteValues["agentId"]?.ToString() ?? string.Empty;
    return agentId switch
    {
        "agentic_chat" => ChatClientAgentFactory.CreateAgenticChat(),
        "backend_tool_rendering" => ChatClientAgentFactory.CreateBackendToolRendering(),
        "human_in_the_loop" => ChatClientAgentFactory.CreateHumanInTheLoop(),
        "tool_based_generative_ui" => ChatClientAgentFactory.CreateToolBasedGenerativeUI(),
        "agentic_generative_ui" => ChatClientAgentFactory.CreateAgenticUI(),
        "shared_state" => ChatClientAgentFactory.CreateSharedState(jsonOptions.Value.SerializerOptions),
        _ => throw new ArgumentException($"Unknown agent ID: {agentId}"),
    };
});
