Hey folks, sharing a quick solution on a strange issue which I faced today.

I was having both Azure SDK installed on my machine i..e SDK version 2.2 and 2.3, I went ahead and uninstalled all components in SDK 2.3 and tried building my one of azure project which was based on SDK 2.2

Here was the issue I was facing after cleaning and building solution using Visual Studio 2013

The "DeleteCurrentDeployment" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.ServiceHosting.Tools, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Solution:

Re-install the Azure emulator using Azure SDK 2.2 and hurray!! the error is gone.
