Tfs Automation - keep user images in sync with active directory

In a previous post I shows how to set user images to be same as active directory in a console application.

I have updated this code to run as a recurring ITeamFoundationJobExtension .
 The first file creates the job in TFS to run every 24 hours, and runs it once right now.

The second file is the updated code that is now a TFS Agent Job, this required a few changes to the code to run against the server api instead of the client one. They're fairly similar but the client api tends to be a bit more friendly.

Installation
Copy the compiled job to c:\Program Files\Microsoft Team Foundation Server 11.0\Application Tier\TFSJobAgent\plugins and restart the agent service. Then run the console application to register the job. Finally check the state of the job by looking in the tfs database

select * from tfs_configuration.dbo.tbl_JobHistory where jobid = 'fa60c04e-c996-413e-8151-15933f5a2bac'
