As far as I remember I´ve never been able to insert snippets from the IntelliSense popup menu. If I, for instance, start typing switch, the IntelliSense menu will appear, and then I select the switch snippet and press, either tab or enter, but all I get is switch in my code.
The snippet does properly appear when I press Ctrl + K and then X and select the snipped from the list. Am I doing something wrong or is my VS bugged?
In order to insert a snippet you need to type TabTab. The first Tab inserts the selected word and the second Tab expands the snippet.
