Where is the NuGet package for Microsoft.WindowsAzure.ServiceRuntime?
The latest Windows Azure SDK is 1.7 so If you need updated Microsoft.WindowsAzure.ServiceRuntime you would have to manually install the SDK in your machine and add those references to your role.
For anyone still battling, make sure you look under Assemblies > Extensions ;) This has now got me twice within 3 months!
I had a similar problem.
Option 1)
I added a dll
libray in my Google Drive Storage: Microsoft.WindowsAzure.CloudDrive
In this case you should download and create a "static" link.
Option 2)
and I found a NuGet Package:
Azure SDK 2.2 DLLs
PM> Install-Package AzureSDK2.2DLLs
If you need more information, please contact me.
