Emulator crashing when using C# markup for hot reload
Description
I have followed David Ortinau's blog: https://dev.to/davidortinau/c-ui-and-net-hot-reload-a-match-made-in-net-maui-243f and James Montemagno's YouTube video: https://www.youtube.com/watch?v=cyz_fKE5wQI that teaches how to use hot reload on C# markup. Unfortunately after invoking hot reload, it crashes.
Steps to Reproduce
- Follow the two links above
- Create a UI using C# markup
- Invoke hot reload
Link to public reproduction project repository

I don't believe this would be specific to the MAUI UI repo. This exception is being thrown by the Mono Soft Debugger and would, most likely, happen regardless of if you were trying to hot reload from a MAUI UI application or a .NET Android one. But I'm not sure if it maybe could be tooling within Visual Studio causing the debugger libs to fail, or something else. Or maybe it is MAUI UI specific.
@thaystg @lambdageek What do ya'll think?
@echolumaque which version of VS are you using?
Hello @thaystg , I am using Visual Studio 2022 17.7.1. Let me know how I could help you if you need further assistance from me.
Thanks!
@echolumaque can you share the sample app that reproduces the issue?
@thaystg, you can try it here: https://github.com/Organisasyon-ng-mga-Malalakas/HealthMate/tree/emulator-crash-test. Here's the concerned files:
What's happening is that hot reload is now not being invoked (changes not showing on the emulator) but when I put a breakpoint on line 64 of SchedulePage.xaml.cs, and hit save which invokes hot reload, it crashes with the same exception.
Sorry it's just a quick test of my existing code so it's quite messy. Let me know if you need something from me.
Thanks again!
Having the same issue, using MAUI Blazor recently updated to net8 - starting the App in Android Emulatur, doing any change in a C# markup page, kills the process. This means i can't use hot reload at all right now, which is causing a huge loss in productivity. We are considering moving to Flutter.
