I am using EF5 beta1 and while I was able to run the \"Update-Database\" before. Now that I shut down Visual Studio, I cannot get it to run. I get the following error:
I had this same problem, and the origin of it was on my path name, I had on my path a directory name with straight brackets, like this: C:\[PROJ]\TestApp.
When I removed the brackets, to C:\PROJ\TestApp, it started to work just fine...
