Hi,
I am using VS 2022 and have a .NET MAUI project. The issue is that Live Preview doesn't seem to work. I watched the video here: https://www.youtube.com/watch?v=nEOvX3YKw_E 

However, I get the error shown below and I don't have the debug menu at the top of the running title bar as shown in the other screenshot.

How do I get this to work?
Thanks,
Clint

    The same problem affects me as well.

    I have upgraded to version 17.4.4, but I am still having the same problem. The XAML live preview works just perfectly with.net6, but not with.net7. I have enabled all the parameters and options. but no use.

    Hi @CFos ,

    Welcome to Microsoft Q&A!

    Are you using the latest version of VS2022? Please update your VS2022 to the latest version through Visual Studio Installer.

    Then, go to Debug > Options > XAML Hot Reload and make sure that the “Enable XAML Hot Reload” option is selected.

    If it persists, I suppose it may be a known issue: https://developercommunity.visualstudio.com/t/NET-MAUI-Hot-ReloadXaml-Live-Preview-n/10198694?entry=problem&q=XAML+live+preview+not+working

    You can also vote and add your comment in that ticket.

    Sincerely,

    Anna

    Thanks for the reply! I upgraded to the latest VS2022 ( had 17.4.1 and updated to 17.4.3) but it still shows the same issues. Hot Reload is enabled as shown below. Screenshots taken when debugging MAUI app.
