Even XAML Hot Reload also not working though the status says it is connected.

The stack trace for the "Edit and Continue" unavailable error is:

I am getting the exact Error with latest updates to Visual Studio 2022 (17.0.5). The impact of this error is huge. It completely disabled Hot Reload, and therefore hugely increasing the development time. Please fix ASAP.

It's safe to say, nobody seems concerned with fixing this problem. Apparently they're too busy crippling features in dotnet cli...

Hello,

Welcome to our Microsoft Q&A platform!

XAML Hot Reload reflects the changes of the xaml code, it cannot work for the code behind. I tested the Edit and Continue function on Xamarin.Form and Xamarin.Android, both don't work. However, it works as excepted while debugging in a Console app, which means the function is not depreated. There may be a potential issue with the function on Xamarin part, it's suggested to send a feedback to VS community for a solution. Please see How to report a problem with Visual Studio - Visual Studio | Microsoft Learn.

Best Regards,

Jarvan Zhang

I tried to register the issue in VS Feedback. It directed me to this post.

That one's status is "Fixed and Pending Release". As advised I downloaded the latest version from VS Downloads site. But the name of the file is same as the earlier download that I have installed. Also the VS Installer app says my install is up to date. So I think the fix is not yet in a Release. Appears I will have to wait further as I don't use Previews. It is supposed to be fixed in Preview 3.

I reported this issue for VS 2019. Now I am using VS2022 and this banner appears even now. Worse, even XAML Hot Reload doesn't work. Something has broken in the basic code and it appears no one is interested to resolve this issue.

This issue has been reported hundreds of times, and I am sure lots of reports you must have received using the method you are describing. This is an important issue for Blazor development. Please prioritize it accordingly.

Isn't this the place to report the problem? Are we supposed to do the support work for you?

Ditto! Good question. I need a solution immediately, too.
