In Visual Studio, make sure you open CommunityToolkit.Maui.Markup.Sample.sln, not CommunityToolkit.Maui.Markup.Sample.csproj.
The solution is to build CommunityToolkit.Maui.Markup.SourceGenerators.csproj before building CommunityToolkit.Maui.Markup.csproj, before building CommunityToolkit.Maui.Markup.Sample.csproj. Building CommunityToolkit.Maui.Markup.Sample.sln will do this for you automatically.
Long story short, the .TextCenter() extension methods are generated using Source Generators.
SimonORorke commented
I did open CommunityToolkit.Maui.Markup.Sample.sln and attempted to build/rebuild the solution. I have now also tried building/rebuilding the three projects in the solution one at a time, in the order that you specify. The CommunityToolkit.Maui.Markup.SourceGenerators.csproj and CommunityToolkit.Maui.Markup.csproj builds both succeed, with no errors or warnings. Unfortunately the CommunityToolkit.Maui.Markup.Sample.csproj build still fails with the errors and warnings that I reported.

@SimonORorke the path on disk looks long to me. Are you familiar with Windows path limits? This page shows how to enable long paths which may solve your issue:
SimonORorke commented
@bijington Thanks for the suggestion. I have enabled long path names in the registry, as instructed in the article. To be safe, I then rebooted my PC before retrying the compilation. Unfortunately, it made no difference. (By the way, as you have probably anticipated, the unit test project won't compile either: that results in 19 errors).
I have also tried compiling a copy of the solution with a much shorter path: "C:\Markup\samples\CommunityToolkit.Maui.Markup.Sample.sln". That did not help either.

Hey @SimonORorke! I finally figured this out. It's due to a regression in Microsoft.CodeAnalysis.CSharp v4.3.0: dotnet/roslyn#63780.
Downgrading to v4.2.0 fixed it.
SimonORorke commented
@brminnick Ha, yes I can see it was a tricky one, as there was nothing you at the Markup team had knowingly done yourselves. Been there! The fix worked for me. Well done!
