Hi to all.

I'va translated a Xamarin project into MAUI environement. The error gived by the compiler is the follower:

...

Code="MA001"

	Text="This project or a dependency has imported the Xamarin.Forms packages. .NET MAUI is not compatible with Xamarin.Forms and is unable to build. Please remove Xamarin.Forms or the project/package dependency that is using Xamarin.Forms."

	Condition="'$(_XFTargetsImported)' == 'true'"/>

</Target>

My problem consists in the fact that the NUGET package Xamarin.Forms is visible in the NUGETs packages but it is impossible to disinstall (the button Install is present but not Disinstall).

In the code is no more present the string "XAmarin.Forms".

Thanks in advance for any suggestion

    Probably you are using a nuget package that depends on Xarmin forms. List dependencies to find the package(s) you must replace:

    dotnet list package --include-transitive

    Hello @Paolo Mossa ,

    Thanks for your question.

    If the Uninstall option is unavailable for Xamarin.Forms, consider examining the dependency tree to see whether the package is being brought in through another NuGet package.

    You can refer to these following steps:

    1. In Visual Studio, go to Solution Explorer > Dependencies > Packages.
    2. Expand your installed packages to look at their sub-dependencies. Find the older package that has Xamarin.Forms listed inside it.
    3. Go to the NuGet Package Manager and uninstall that older package.
    4. Install a new, .NET MAUI-compatible version of that package, or find an alternative library. 5. Close Visual Studio, manually delete your bin and obj folders in File Explorer, and rebuild the project.

    I hope this addresses your question. If this response was helpful, please consider following the guidance to provide feedback. Thank you.
