I mostly code WebForms and am new to MVC. When I first heard of this EmptyResult class, I was quite confused and I couldn't figure out why it was necessary. Then I searched StackOverflow (SO) and found these quality explanations:
http://stackoverflow.com/questions/5452172/mvc3-return-emptyresult-when-its-a-good-idea-to-return-this
http://stackoverflow.com/questions/8561038/return-new-emptyresult-vs-return-null
While the above SO threads are available (if necessary), it would also be useful if Microsoft or a member of the community posted a small code example showing an action that returns the EmptyResult.
Best,
