WPF Debounce trick

Sometimes you have to appreciate the power and simplicity that WPF(and by extend XAML has to offer). While having to do a lot of voodoo magic with Reactive Extensions to support debouncing, in WPF it can be reduced to one binding property,  the Delay Binding Property.

You can use the WPF Delay binding property to debounce binding events. For example following code will debounces the key input until nothing changes for 0.5 seconds:

Text="{Binding UserName,UpdateSourceTrigger=PropertyChanged,Delay=500}"

Sweet!
