Visual Studio not auto-building on run

Right-click on configuration manager and check to see if build is checked for project in question
Also in Tools > Options > Projects and Solutions > On run when projects are out of date > Always Build

If above not succeeded then keep these options, but also do a Clean (of solution -works or of project -not tested)
