.NET 4.5 added asynchronous language features for C# and VB. For the most part, this has made it much easier to improve a user interface’s responsiveness—you can use asynchronous APIs to perform potentially slow work in a way that will not cause your user interface to freeze, and yet you can use simple programming techniques that look very similar to those used in single-threaded code. However, this is not a panacea. There are some kinds of slow, IO-oriented work (i.e., the kind of work that often benefits most from asynchrony) where a simple application of these techniques won’t help as much as you might hope.
