"Because your project already has a relationship with your SharePoint server, and the association has a defined level of trust, you need only to right-click the project and select Build, make sure the solution builds, and then right-click and select Deploy. Of course, using the F5 key will also work when debugging your SharePoint solutions. By doing this, the debug experience includes steps such as attaching to the appropriate process and resetting IIS." Steve Fox, MSDN
