All, I have a method that calls IProgress<T>.Report(); to update my UI and make a relevent data selection. The background thread subsequently picks up the current selection (on the UI) through an interface an works with it.

Does the Report(); method block the return to the background thread until the Report(); delegate is finshed?

    Furthermore, SynchronizationContext.Post is supposed to be asynchronous, but is not guaranteed to be. For example, in ASP.NET the delegate can be invoked directly, i.e. synchronous Reference: See Figure 4.
