Windows Runtime, or WinRT, is a platform-homogeneous application architecture first introduced in Windows Server 2012 in September 2012. WinRT supports development in C++/CX (Component Extensions, a language based on C++) and the managed code languages C# and VB.NET, as well as JavaScript and TypeScript. WinRT applications natively support both the x86 and ARM architectures, and also run inside a sandboxed environment to allow for greater security and stability. WinRT components are designed with interoperability between multiple languages and APIs in mind, including native, managed and scripting languages.
