: Today, Microsoft released a new version (1.9) of its Visual Studio Tools for Unity. It's available as a free download from MSDN, and supports Visual Studio 2010, 2012, and 2013.The tool offers "a rich programming and debugging experience" inside of Visual Studio and offers a faster debugger, faster project startup, better handling of C# constructs, and (in Visual Studio 2012 and 2013) one-click game startup while working with the Visual Studio debugger.The add-on is an updated version of UnityVS, a third-party add-on for Visual Studio from SyntaxTree, a company Microsoft acquired last month so it could better integrate Unity support into Visual Studio.You can download it here
