Two-way binding to static property in static class

Question

Is that seriously NOT possible? I have solutions to bind one-way to properties in static classes and certainly i have solutions to bind two-way to static properties in non-static classes... but...

I mean, the workaround is easy, i can just make my static class to a singleton with a static instance getter (see here), but isn't there a proper way??

my class looks something like that:

public static class TestClass
{
  public static string TestProp {get; set;}
}

And now please assume that i properly implement INotifyPropertyChanged in the "normal" way in the setter (omitted for simplicity).

How should the XAML look like to bind two-way to this property? Thanks.

this answer may help: wpf static binding question or this: Binding to static class property

in short, your case would look something like:

{Binding Source={x:Static whatever:TestClass.TestProperty}, Path=.}
