Here's a short screencast I created that demonstrates how I use free productivity enhancers such as GhostDoc (by Roland Weigelt), Regionerate and Visual Studio's built-in refactoring tools to quickly create and maintain skeleton code. It also demonstrates the usage of Regionerate's new Code Layout Browser.
I know there are some commercial tools that do more, but I'm just presenting a free (partial-)alternative. Make sure your speakers are turned on.
