Windows Runtime
Windows Runtime (WinRT), is a platform-homogeneous application architecture first introduced in Windows 8 and Windows Server 2012 in 2012. WinRT supports development in C++/CX (Component Extensions, a language based on C++), JavaScript-TypeScript, and the managed code languages C# and Visual Basic .NET (VB.NET). WinRT applications natively support both the x86 and ARM processors, and run inside a sandboxed environment to allow greater security and stability. WinRT components are designed with interoperability between multiple languages and APIs in mind, including native, managed and scripting languages.
