Blazor Hybrid template doesn't work

arteeh commented 3 months ago

Description

When I create a new Blazor Hybrid app with Visual Studio and launch it on Windows (unchanged), I get an exception on line 9 of MauiProgram.cs (var builder = MauiApp.CreateBuilder();):

System.InvalidProgramException: 'Common Language Runtime detected an invalid program.'

Exception source: Microsoft.Extensions.DependencyInjection.Abstractions

The program crashes after I continue.

Tried in Jetbrains Rider as well, got the same exception but in App.g.i on line 75 (if (global::System.Diagnostics.Debugger.IsAttached) global::System.Diagnostics.Debugger.Break();)

When I debug the template in Android 11 emulator, the app crashes on startup and my output says this:

[monodroid-assembly] open_from_bundles: failed to load assembly Microsoft.Maui.Controls.Xaml.dll
[monodroid-assembly] open_from_bundles: failed to load assembly Microsoft.Extensions.Configuration.dll
[monodroid-assembly] open_from_bundles: failed to load assembly Microsoft.Extensions.Configuration.Abstractions.dll
[monodroid-assembly] open_from_bundles: failed to load assembly Microsoft.AspNetCore.Components.WebView.Maui.dll
[monodroid-assembly] open_from_bundles: failed to load assembly Microsoft.Extensions.Logging.Debug.dll
...
[libc] Fatal signal 11 (SIGSEGV), code 128 (SI_KERNEL), fault addr 0x0 in tid 18668 (name.hybridtest), pid 18668 (name.hybridtest)

Steps to Reproduce

Install latest version of Visual Studio (Professional)
Use the Visual Studio Installer to get MAUI
Create .NET MAUI Blazor Hybrid App on .NET 8
Set the launcher to windows instead of mac/android
Debug
Install whatever dotnet workloads you don't have when it tells you
Debug again

Android:

Install and launch an Android 11 emulator
Set the launcher to android instead of windows/mac
Debug

Jetbrains Rider:

Create a new solution/project and select Other > MAUI > Target framework: .net8.0 and Type: Blazor Hybrid App
Set the startup configuration to the windows one
Debug

Already tried:

clean and full rebuild several times
deleting bin and obj
an older project that worked at some point (same exception) (i don't know which version I used then, I did update Visual Studio earlier today)
Visual Studio repair
PC restart
dotnet workload update
dotnet new -i Microsoft.Maui.Templates

I actually did experience this issue #19489 earlier, but now I can't reproduce it anymore. I saw it when I tried to run my old app which started this troubleshooting journey, and I think I saw it with a fresh template as well. Maybe it's gone because I ran dotnet new -i Microsoft.Maui.Templates?

But I just get crashes and InvalidProgramExceptions now.

The problem was that I needed a certain Windows SDK. Probably Windows 10 10.0.19041.0, but I just installed all of them. You can find it under the 'Desktop development with C++' section (or Individual components) (makes sense for something maui clearly depends on).

Now both the templates and my old project run properly, including on my android emulator.

dotnet / maui
