Get this? Windows Azure MMC, Could not load file or assembly 'Microsoft.Samples.AzureManagementTools.PowerShell, Version=1.1.3779.27370, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

You probably have a previous version of the Windows Azure SDK. Delete all but the latest folder from ‘C:\Program Files\Windows Azure SDK’.  For me, I had to delete the folder ‘C:\Program Files\Windows Azure SDK\v1.0’
