@davidortinau - Can you set the environment variable below to enable more logs for C# Hot Reload, then attach them. Also, can you note the versions of the C#, C# DevKit, and MAUI extensions you are using. They are internal versions, what's about to be published to prerelease tomorrow, right?

@BretJohnson correct, I'm on pre-release of everything here. MAUI v1.3.29 |
|
Any progress on this? |
@lucasmsoares96 - Assuming you see this issue, would you mind following the steps here, attaching the logs: #1450 (comment). Thanks much. |

In the logs above, changes were made to 2 files: WebApp.csclass WebApp
{
static void Main(string[] args)
{
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
var chatbot = new Chatbot();
app.MapPost("/ChatMessages", async (ChatMessages person) =>
{
Console.WriteLine(person);
var result = await chatbot.StartAsync(person.Text);
return Results.Ok("empty return"); // comment this
// return Results.Ok(result.Content); // uncomment this
});
app.Run();
}
record ChatMessages(string User, string Text);

{

new LightModel { Id = 2, Name = "Porch light", IsOn = false },

var light = lights.FirstOrDefault(light => light.Id == id);
if (light == null)
{
return null;
}
light.IsOn = isOn;
return light;

}When I finished restarting the debug, experiment 1 (commenting and uncommenting the returns line in file 1) stopped working. LogsTrace.log |

One more thing: the hot reload button is also not working.

Type: Bug
In this version I'm unable to C# hot reload. I've cleared my bin/obj folders. All I get in the output is messages like this. I'm using .NET 9 Preview 7 and targeting net9.0-maccatalyst and net9.0-ios.
