Build Failed after upgrading Maui.Markup package from 1.1.1 to 3.3.0

[gerhartz]

I upgraded our Maui project that was using CommunityToolkit.Maui.Markup 1.1.1 --> 3.3.0 and am now unable to build the project. I'm probably missing a step on my end, but I can't figure out what needs to change.

I'm getting a warning CS9057 and an Error CS1061. I imagine the build is failing because of the Error CS1061 but even when I open the file TestSliders.cs there is no IDE error that it can't find the .TextTop() method.

I'm not sure how to specify the compiler version of 4.7.0.0 anywhere.

Any help is much appreciated!

Build error output:

CSC: Warning CS9057 : The analyzer assembly '/Users/pgerhartz/.nuget/packages/communitytoolkit.maui.markup/3.3.0/analyzers/dotnet/cs/CommunityToolkit.Maui.Markup.SourceGenerators.dll' references version '4.7.0.0' of the compiler, which is newer than the currently running version '4.6.0.0'. 1>TestSliders.cs(39,18): Error CS1061 : 'Label' does not contain a definition for 'TextTop' and no accessible extension method 'TextTop' accepting a first argument of type 'Label' could be found (are you missing a using directive or an assembly reference?)

Here's some output of my environment:

Some things I've tried that haven't seemed to make any difference...

1. Deleted all the bin and obj folders in my projects and reloaded project
2. Updated my Visual Studio with the latest .NET version
3. Added a using statement to MauiProject.cs for using CommunityToolkit.Maui;. We already have a global using statement for this so it did not do anything.
4. Cried a little bit & said a prayer. No luck there.

Thank you in advance for pointing me in the right direction!

Interesting - I removed all the usages of these and now its building:

TextCenter()
TextCenterVertically()
TextTop()
TextEnd()

No more warnings or errors. But it seems like these methods are still in the SDK to use 🤔

(See Issue #250)

I've experienced this bug too, but haven't figured out the fix yet.

In my experience, it happens on macOS but not on Windows.

However, it works in our CI builds. This leads me to assume it's a local environment configuration problem.

I'll keep poking at it to see if I can figure out the culprit.

In the meantime, check out our CI Pipeline environment configuration to see how to best configure your local environment: https://github.com/CommunityToolkit/Maui.Markup/blob/main/azure-pipelines.yml

Workaround

An easy work-around is to downgrade to CommunityToolkit.Maui.Markup v3.2.0. The only new feature added to v3.3.0 is .NET Hot Reload support.

Downgrading to 3.2.0 works just fine. And yes I am on a Mac.

Thank you for the help!
