GotDotNet is down finally. Even though Microsoft promotes CodePlex harder and harder these days, there are a lot of projects drowning with GotDotNet.
I don’t know much about other projects, but AssemblyInfoTask is a must if you want to control your projects version number in a convenient way.
But will it be back? Who knows? It is quite sad to see such a useful project gone.
(Updated: Yes, it is back.)
