net8 + Autofac + MAUI #5423

I know that net8 is still in preview, but I thought I'd ask in case someone in the MAUI subteam might have dealt with this yet:

  • Have net7.0 MAUI abp app
  • Try upgrading to net8 preview (currently 6)
  • Run

Expected: App should run Actual: Crash related to DI

    Trying to create the sample issue here: https://github.com/kfrancis/net8-maui-autofac-repro

    MauiApp1 is just a simple maui app, that was net7.0 with autofac (not abp) and was working. Then upgraded to net8 preview 6 and it still works.

    MauiApp2 is the same, but I suspect the issue comes into play with abp autofac so I'm trying to prepare a simple example of that.

    Hello kfrancis Let me check this out. Probably some APIs or XAML extensions might be changed that we used.

Made with ❤️ on ABP v9.1.0-preview. Updated on December 10, 2024, 06:38
