If one follows the tutorial here and does so on a box running Windows 7, chances are that they'll receive the following error ...

The term 'Add-Migration' is not recognized as the name of a cmdlet, function, script file,
or operable program. Check the spelling of the name, or if a path was included, verify
that the path is correct and try again.
At line:1 char:14
+ Add-Migration <<<<  MyFirstMigration
    + CategoryInfo          : ObjectNotFound: (Add-Migration:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

... when trying to execute Add-Migration MyFirstMigration.

This is due to the fact that Powershell may be Version 2 or 3. It needs to be Version 4 for this to work.
I had this issue on two separate W7 boxes on which I tried playing with EF7, so I think other people may run into this as well. The first time it took me almost a day to figure this out. So a hint towards this in the tutorial may be a good idea.
Installing an update from here fixed it.

📝 Document min PowerShell version
62ea44d 
For Package Manager Console commands you need PowerShell 3.0 or newer.
Adding this to the pre-req section. Doesn't apply to UWP since you need
Windows 10 for that anyway.

The minimum version probably should also be mentioned here ...
