GUID + VS2012 + R#
Sometimes really small features that are implemented in add-ins can make developer feel happy. This small features can speed up software development process. Last time I had to prepare an application installer – I have chosen WiX. In this solution you need to add to each element in installer GUID. Hopefully I am using R# with Visual Studio 2012. And the R# generates GUIDs out of the box. You only need to enter [mark]nguid[/mark], press [mark]tab[/mark] button and choose proper format.
