AsyncCommand in .NET MAUI

https://devblogs.microsoft.com/dotnet/introducing-the-net-maui-community-toolkit-preview/#what-to-expect-in-net-maui-toolkit

The .NET MAUI Toolkit will not contain the MVVM features from Xamarin Community Toolkit, like AsyncCommand. Going forward, we will be adding all MVVM-specifc features to a new NuGet Package, CommunityToolkit.MVVM.

install CommunityToolkitMVVM 8.0.0

[RelayCommand]
async Task your_method (){...}
