Strange as it seems, only shows the power of the framework. We’ve been moving TaskBeat from VisualStudio 2005 to 2008, to 2010, 2012, 2013 without major changes, or no changes in most of the cases. Worst case scenario, the change was cosmetic and didn’t break the build. Until today we’ve moved to Visual Studio 2014 and got the first compilation error. Impossible. Yes, with Rosylyn, we’ve finally found our first compiler issue and resolved it within 10 minutes. Still shows the power, and stability of the framework. Never try the same with minor release of Ruby or PHP.
