Prevent UI from freezing without additional threads

Question

What solutions do I have if I want to prevent the UI from freezing while I deserialize a large number of UI elements in WPF? I\'m getting errors complainig that the objects

Answer 1

Try freezing your UIElements. Frozen objects can be passed between threads without encountering an InvalidOperationException, so you deserialize them & freeze them on a background thread before using them on your UI thread.

Alternatively, consider dispatching the individual deserializations back to the UI thread at background priority. This isn't optimal, since the UI thread still has to do all of the work to deserialize these objects and there's some overhead added by dispatching them as individual tasks, but at least you won't block the UI - higher priority events like input will be able to be interspersed with your lower priority deserialization work.
