Common Language Runtime

Template:Short description Template:Multiple Template:Program execution The Common Language Runtime (CLR), the virtual machine component of Microsoft .NET Framework, manages the execution of .NET programs. Just-in-time compilation converts the managed code (compiled intermediate language code) into machine instructions which are then executed on the CPU of the computer.<ref name="msdn-clr">Template:Cite web</ref> The CLR provides additional services including memory management, type safety, exception handling, garbage collection, security and thread management. All programs written for the .NET Framework, regardless of programming language, are executed in the CLR. All versions of the .NET Framework include CLR. The CLR team was started June 13, 1998.

CLR implements the Virtual Execution System (VES) as defined in the Common Language Infrastructure (CLI) standard, initially developed by Microsoft itself. A public standard defines the Common Language Infrastructure specification.<ref>Template:Cite web</ref>

During the transition from legacy .NET technologies like the .NET Framework and its proprietary runtime to the community-developed .NET Core, the CLR was dubbed CoreCLR.<ref>Template:Cite web</ref> Today, it is simply called the .NET runtime.<ref>Template:Cite web</ref>
