Is it possible to filter on IObservable<bool>?

[SuperJMN]

Doing something like this:

class Model
{
     public IObservable<bool> IsSelected { get }
}

sourceCache
   .Connect()
   .Filter(x => x.IsSelected)
   .Bind(out var collection)
   .Subscribe();

You can use FilterOnObservable that will create an IObservable<bool> for each item that controls whether or not that item passes the filter.

This should work as expected (assuming sourceCache contains Model instances):

class Model
{
     public IObservable<bool> IsSelected { get; }
}

sourceCache
   .Connect()
   .FilterOnObservable(x => x.IsSelected)
   .Bind(out var collection)
   .Subscribe();
