Could not load file or assembly 'System.Management.Automation, Version=3.0.0.0 running the BizTalk 2013 Power Shell Provider

Trying out the brand new BizTalk 2013 Power Shell Provider (https://psbiztalk.codeplex.com/) I got this error:

Add-PSSnapin : Could not load file or assembly 'System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

This happened after installing version 1.3.0.0 (the updated Power Shell Provider for BizTalk Server 2013) on top of version 1.2.0.2 on a Windows 2008 R2 server.

I bit of Goggling suggested that I installed the Windows Management Framework 3.0 (http://www.microsoft.com/en-us/download/details.aspx?id=34595) which I did and now everything works again.
