Using Visual Studio 2013, this morning, I received a message that some tooling had been deprecated (I did not print or write the message down, which I now regret), and that I should restart my computer. Since then, the RazorGenerator custom tool no longer works.
I believe this relates to the following update installed on my computer today, http://support.microsoft.com/kb/2645410
