The term 'Update-Database' is not recognized as the name of a cmdlet

Question

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:

Answer 1

Sometimes when I load VS, I see this in my package manager console:

Value cannot be null.

Parameter name: path1

I have no idea what causes that yet but it seems that something goes wrong during the start-up of the Powershell console which interrupts the registering of specific modules, such as the EF powershell extensions. You can just manually load it however:

Import-Module .\packages\EntityFramework.6.1.1\tools\EntityFramework.psm1

Make sure you replace 6.1.1 with whatever your current version of Entity Framework is.
