title: Could not load file or assembly 'Microsoft.WindowsAzure.ServiceRuntime, Version=2.0.0.0
body: <p>We are using Azure SDK 1.8 and it working fine on local. we are using TFS hosted build controller to deploy on azure.</p>
  
  <p>It was working fine before but sudden today we getting this error although we have no azure sdk dll version changed but online we get this error. Is this because of TFS build controller upgraded with new sdk? and strange thing this build is showing successful every time.</p>
  
  <p>In TFS build service I found this strange stuff why it is referencing to v2.0 sdk.
