Deploying CRM customization using TFS

Hi,

I am using the following link to create a build definition to export CRM customization from one env to another

http://waelhamze.com/2013/11/25/how-to-create-an-automated-tfs-build-for-dynamics-crm-solutions/ and facing the below issue:

TF215097: An error occurred while initializing a build for build definition \MSDynamics.Environment.BuildTemplates\CRM Staging: The build controller cannot deserialize the process parameters of the build. Make sure the process parameters are compatible with the assemblies on the build machine. Details: Cannot create unknown type '{clr-namespace:Xrm.Framework.CI.Common;assembly=Xrm.Framework.CI.Common}SolutionPackageType'.

any help or tip will be helpful. Thanks.
