Windows Azure Training Kit Guestbook Demo get error when building - visual-studio-2010

Question

This is the error i receive when i build the GuestBook demo. Does anyone have any idea what would be causing this? I'm assuming something got installed wrong but i can't figure out what. I'm also assuming it has something to do with MSBuild.
Error 1 The "DeleteCurrentDeployment" task failed unexpectedly.
System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'.

Solution:
Make sure you have installed every component for Windows Azure. http://www.microsoft.com/en-in/download/details.aspx?id=35448 This particular error says that the system is missing Windows Azure Emulator.

Answer 2

It seems that the build tries to delete an existing azure deployment, but fails doing so. Please make sure, that the current Azure SDK is installed correctly.
