Maui updates XAML code, Hotreload does not work

Jay-57blocks commented 4 months ago

Description

Steps to Reproduce

Hotload doesn't work in my project, but I create a new project and it works normally and I don't know how to make it work

Link to public reproduction project repository

No response

Version with bug

8.0.7 SR2

Is this a regression from previous behavior?

Not sure, did not test other versions

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

Did you find any workaround?

I guess it might be the Mac version I was using, and I remember receiving a reminder telling me that hot updates were not working, but I accidentally clicked on the no longer reminder

This is due to a breaking change in MAUI for scope validation, introduced in .NET 8, Hot Reload was pulling values from the service container (Specially Dispatcher) that broke, so the code within Xaml hot reload had to be updated which occurred for Visual Studio. Since Visual Studio for Mac received partial/kinda/sorta support for .NET 8 in general, and is heading on the path to deprecation, this fix was not brought forward to the Mac, as supported between VS and VSMac has diverged greatly since it started to be deprecated, patching it is not trivial.

I'm sorry, but most likely this will not be fixed for VSMac.

@drasticactions So are there any temporary solutions? example,

Change the project Net version to.Net7? But if I create a new project and it uses. net8, hot reload will work fine
Or use VSCode? As far as I know, VSCode maui is currently only a preview and I'm not sure if it is stable enough.
