Updating Visual Studio 2022 to 17.12.1 breaks all Maui builds #26020

drewrobey · 2024-11-21T11:32:38Z

Description

We have a 5 Maui projects, and since updating Visual Studio last night, all now fail to build, with a variety of new error messages:

resource style/Maui.SplashTheme (aka XXXXXXX:style/Maui.SplashTheme) not found.
failed linking references.
The type or namespace name 'MauiAppCompatActivity' could not be found (are you missing a using directive or an assembly reference?)
Cannot implicitly convert type 'XXXXXXX.MainActivity' to 'Android.App.Activity'
'Platform' does not contain a definition for 'OnRequestPermissionsResult'
The name 'Resources' does not exist in the current context
style attribute 'attr/windowNoTitle (aka XXXXXXX:attr/windowNoTitle)' not found.
style attribute 'attr/windowActionBar (aka XXXXXXX:attr/windowActionBar)' not found.
The type or namespace name 'MauiUIApplicationDelegate' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'MauiWinUIApplication' could not be found (are you missing a using directive or an assembly reference?)

All of these projects built successfully yesterday before the update, both on Android and iOS.

Steps to Reproduce

Update Visual Studio to 17.12.1
Attempting to build any Maui project.

Besides updating Visual Studio did you update anything else? At the very least updating Visual Studio probably updated your workloads. Are you using $(MauiVersion) in your csproj file to reference the .NET MAUI version? If yes, then also your .NET MAUI SDK got updated.

Do you have some more complete build logs or anything besides just the error messages?

Are you building .NET 8 or .NET 9? What is the output of dotnet --info and dotnet workload list?

What can typically help is delete the bin & obj folders, do a Clean, do a Rebuild to make sure nothing cached is left behind and everything is build with the latest and greatest.

drewrobey · 2024-11-21T11:49:13Z

Hi @jfversluis

The VS update was the first thing we did this morning, and we close every day with working builds, so nothing else has changed.

I'm attempting a dotnet workload update now. All errors seem to be connected to Visual Studio no longer recognising the Maui compatibility toolkit on both Android and iOS, so I'm guessing that solving that will eliminate all the errors.

jfversluis · 2024-11-21T11:50:36Z

Let us know how it goes!

drewrobey · 2024-11-21T12:02:16Z

Unfortunately that hasn't fixed it. The core lynchpin error, for Android at least, is:

The type or namespace name 'MauiAppCompatActivity' could not be found (are you missing a using directive or an assembly reference?)

We use the compat toolkit in all our projects, so the class signature on Android's MainActivity is always:
public class MainActivity : MauiAppCompatActivity

...and if it can't resolve that, then it can't build anything else, or find any of the compat stuff used elsewhere.

EDIT:
I've just created a new Maui project, using compat, and that won't build either, so something is awry with the VS update.

MitchBomcanhao · 2024-11-21T13:03:57Z

what do you mean by compat toolkit? do you mean a reference to Microsoft.Maui.Controls.Compatibility?
that line for public class MainActivity : MauiAppCompatActivity has no connection to Microsoft.Maui.Controls.Compatibility

drewrobey · 2024-11-21T13:05:37Z

Well if that's not the compat toolkit stuff then the build issue is at a higher Maui level than the compat stuff.

EDIT:
If we remove Microsoft.Maui.Controls.Compatibility from Nuget then we can build. I shall experiment further.

MitchBomcanhao · 2024-11-21T13:08:25Z

well, on microsoft's maui documentation it says to remove the compatibility package reference when going from .net8 to .net9

drewrobey · 2024-11-21T13:10:10Z

Interesting. We'd not moved any of the apps to .net 9 yet, but I think it might be time.

MitchBomcanhao · 2024-11-21T13:11:59Z

if you updated maui to 9.0, aren't you using a .net9 package?

drewrobey · 2024-11-21T13:16:04Z

Not until this morning.

drewrobey · 2024-11-21T13:28:46Z

Solved it. The sequence that worked for us is:

Upgrade projects to .net 9.
Purge Nuget cache and restore.
Update all Nugets to latest versions (Microsoft.Maui.Controls and Microsoft.Maui.Controls.Compatibility in Nuget must be same version - v9.0.10 - or apps won't build).
Delete bin and obj folders.

We've done this on 3 of 7 workstations, and things will build again (with a ton of new warnings that weren't there before, but never mind).

I'll presume that the other 4 will also succeed with this, so I think this can be closed.

philosowaffle · 2024-11-27T16:52:40Z

Does anyone have steps for resolving this without having to upgrade to .NET 9 (currently on .net 7)?

Example error: GitHub Action runners.

I do not have the bandwidth to upgrade all my projects to .NET 9 right now. That is on the roadmap for 2025.

This fixed my local builds in Visual Studio, but it did not fix GHA builds.

drewrobey · 2024-11-27T17:48:04Z

@philosowaffle Are you using Microsoft.Maui.Controls.Compatibility?

There was another VS update released in the last 24 hours, have you got this yet?

NickDrouin · 2024-11-27T19:48:53Z

I was going to try out Maui today, I'm hitting this same problem, I installed 17.12.2.

I can build and run a new Maui .net8 project, I can build a new .net9 maui project, I can't build the sample project from:

@NickDrouin I've never used one of the sample projects, so I can't comment on that directly, but .Net 9 has certainly changed much of the former ways Maui was configured to run (some methods have been tweaked, some methods deprecated and replaced, etc) so there's a distinct possibility that that sample project is now out-of-date and won't quite meet the latest standards.

Sounds as a real world consideration...

Eventually found my way to this issue and a solution that would allow me to build .net7 workloads in GitHub Actions.

The changeset is here, but I believe the magic sauce was adding these two steps:

     - name: Set global.json
      run: dotnet new globaljson --sdk-version 7.0.100

    - name: Restore MAUI Workloads
      run: dotnet workload restore

It certainly works in development PC's and also Github Actions.
We have checked and you can even use "--sdk-version 8.0.404" to build your MAUI 7 app.
I´m not sure what´s the effect of using sdk 8 to build net/maui 7 apps. Does anyone know the difference?
But I´m pretty sure this was happening with our daily buildings in our development machines with VS2022 17.11 and earlier too.
