ASP.NET Tooling in Visual Studio 2015
With Visual Studio 2015, we reimagined the project system for ASP.NET from the ground up, making it lighter-weight and more robust. Developers can make changes to their source and see it reflected in the browser with just a refresh. Or add files to the filesystem and see them automatically reflected in your project. All of these new features, including building, running, scaffolding, and unit testing is available from a cross-platform friendly command line. Sayed Hashimi demonstrates some of these new capabilities.
