2. Go to the DLM Automation add-ons webpage.
3. In the Microsoft Team Foundation Server (TFS) section, click Download plugin. 
4. After the TFSBuildPlugin.vsix installer file has downloaded, double-click it to start the installer. 
5. When installation is complete, restart Visual Studio.
6. On the machines running your build agents, open Windows Services (services.msc). 
7. In the list of services, right-click on Visual Studio Team Foundation Build Service Host [year] and select Restart.

You're now ready to use the plugin. See Using the TFS Build plugin.
