I once embarrassed myself by recommending a GUID generator site to a colleague. “That’s great,” he said, “but I just use the one built into Visual Studio.”
The Visual Studio tool was a bit clunky, but it became part of my regular toolkit. Until I started using the 2013 Community edition, that is. It would seem to have disappeared from there, or at least isn’t on the usual Tools menu. A quick google should find where it’s moved to, I thought, but instead I discovered something even better. You probably know about it already and I’m embarrassing myself all over again, but in case you don’t and on the remote chance that I’m not:
You can create a new GUID using Resharper by typing nguid and pressing tab.
That’s it. So much simpler than the old Visual Studio tool.
