What would cause a 'could not load file or assembly' error concerning 'Microsoft.WindowsAzure.Configuration'?
This was an issue with the Microsoft.WindowsAzure.Configuration assembly, version 1.7.0.2
Temporarily fixed by rolling back to either 1.7.0.1 or 1.7.0.0 and then permanently fixed in 1.7.0.3
Had same problem. I reverted Microsoft.WindowsAzure.ConfigurationManager back to NuGet version 1.7.0.1. Now it is working OK.
