[regression] [worked-in:maui]
The "VerifyVersionsTask" task could not be loaded from the assembly C:\Users\joepuhich.nuget\packages\xamarin.build.download\0.11.4\build\Xamarin.Build.Download.dll. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

What NuGet package are you trying to consume that is causing this error?

I don't see any VerifyVersionsTask in Xamarin.Build.Download, so it seems like maybe the NuGet you are trying to use is broken?

i have updated all my nuget packages to androidx from support. everything is running well, but i get this error and i do not know what is wrong. I thought maybe u could help me, by pointing to a nuget package that is used to find "VerifyVersionstask". i have been converting a project from vs2022 to net maui. i think i have all my code ready for final compilation, but i can not get by this error. i do not know where to look to find the solution. I found this "VerifyVersionsTask" code in a dll file , but it does not point to any other files?? any help would be great.

You might want to try creating a new project from a template and adding your NuGet packages one at a time until you find the one that causes it to break.
