[WASM] Multithreading with .Net8 doesn't work because Uno.WASM.MetadataUpdate is compiled with .net7? about uno.wasm.bootstrap HOT 4 CLOSED

Ok, after looking again with fresh eyes and getting hold of the typescript files, I have found the error.

"JSExport with multi-threading enabled is not supported with assembly ${assembly} as it was generated with the .NET 7 SDK" for assembly = Uno.WASM.MetadataUpdate

As I am digging into the unknown (for me), I'm putting this here as it seems like it might make sense to someone more knowledgeable. Meanwhile, I can't immediately see where this assembly is coming from so I will keep digging.

from uno.wasm.bootstrap.

Workaround: Unsuccessfully, tried to find a way to disable hot-reload before the app is loaded in debug mode, but Release mode works properly without an error.

Thanks for the report.

We'll likely need to build this project with net8 instead.

Thanks, can confirm the using latest builds (dev.3455) app now runs fully in debug mode with threading.

However, just for information, when multithreading is enabled, breakpoints are not hit and the browser window is disconnected from the server. The only difference in terms of console messages is the following error in multithreaded mode:

Unable to set option 'no-jiterpreter-traces-enabled' as it's read-only. dotnet.native.js

I'm guessing that's a dotnet issue, though. Work arounds are just console debugging or switching off multithreading temporarily, but at least with shorter compile times of debug mode.
