The version of Microsoft.WindowsAzure.Diagnostics.dll, Microsoft.WindowsAzure.ServiceRuntime.dll, Microsoft.WindowsAzure.StorageClient.dll used by Sitefinity needs to be version 220.127.116.11. The latest SDK for Azure is not installing version 18.104.22.168 in the .NET GAC on the computer where the site is running.
Sitefinity Thunder also uses the assemblies mentioned above therefore you will not be able to deploy the project with it either if their version differs from 22.214.171.124.
Make sure the SDK is indeed installing 126.96.36.199 and after the SDK installation, perform restart of the computer as the installation wizard prompts.
