[BUG] Not Generate PropertyChanged event on .NET Standard 2.1

[dimonovdd]

Describe the bug If I use .NET Standard 2.1 project, no code generation occurs only for PropertyChanged. Everything's fine with .NET Standard 2.0

Expected behavior The following code should be generated:

public global::System.IObservable<global::System.ComponentModel.PropertyChangedEventArgs> PropertyChanged => global::System.Reactive.Linq.Observable.FromEvent<global::System.ComponentModel.PropertyChangedEventHandler, global::System.ComponentModel.PropertyChangedEventArgs>(eventHandler =>
{
    void Handler(object sender, global::System.ComponentModel.PropertyChangedEventArgs e) => eventHandler(e);
    return Handler;
}, x => _data.PropertyChanged += x, x => _data.PropertyChanged -= x);

I thought it might be because of dependencies. I created an empty Xamarin.Forms project with .NET Standard 2.1 and got the same behavior Pharmacist.NuGet.g.cs
