Description

XAML Hot Reload is not working, UI changes are not updated while debugging. The issue persisted with both blazor and native maui tests that I've made.

1. Open Visual Studio Professional 2022 17.1.0 Preview 5.0
2. Create a new project
3. Select .NET MAUI Blazor App
4. Run the app on any platform (debug mode) and change some ui elements
5. Save the changes
6. The view is not updated

Did you find any workaround?

FYI @dotnet/dotnet-maui-blazor-eng team. I think this is a dup of an existing issue.

Ok, so I will mention that if you manually remove all other platforms, it does partially work again, but you have to refresh the page (as in the changes are not immediately visible) by going to another page then re-rendering the old one again. To me, it would seem that the issue is the #if directives (or equivalent via MSBuild) are being ignored.

XAML Hot Reload (As in, editing XAML, not Razor), as of RC1, should be working fine with a MAUI Blazor app. Judging that I think we're talking about the Razor here, that's a dupe so I'm going to close this issue.
