Use community toolkit inside MauiClassLibrary

[lemcoder]

Is there a preffered way of using community toolkit in a MauiClassLibrary project? I have a module with 3 views and I want to use community toolkit, but I keep getting errors regarding the use of xml namespace. I've found a workaround that if I make a mock extension method and add UseMauiCommunityToolkit line - everything works fine:

public static MauiAppBuilder Workaround(this MauiAppBuilder builder)
        {
            builder.UseMauiCommunityToolkit();

            return builder;
        }

It works but I would much prefer not to add useless code inside my module...

adding builder.UseMauiCommunityToolkit(); is required. Alternatively, you can use xmlns with explicit class and assembly

The root cause is the Linker is removing our library because it thinks you are not using it. The Linker scans C# code looking for references to CommunityToolkit.Maui, and if it doesn't find any, it will remove the DLL because it assumes you are not using it; it doesn't know how to scan XAML.

To ensure CommunityToolkit.Maui is not removed by the Linker, you should reference the library in C#; something like this:

var behavior = new EventToCommandBehavior();
