C# desktop app to export TFS query items

Need a C# app that will do the following: 1. Connect to our TFS server using the TFS SDK 2. Run existing query in an existing Team Project 3. Export query to .csv 4. Open saved .csv in Excel The reason we need to do this, is the query spans multiple projects and the current export to Excel functionality that exists in .NET for TFS today doesn't allow this. It only allows you to import work items from a single project.
