As an expert in the field of software development, I can explain the Common Language Runtime (CLR) in the context of C# programming. The Common Language Runtime (CLR) is an integral part of Microsoft's .NET framework. It acts as the execution engine for all .NET applications, including those written in C#. The CLR provides a range of services to .NET programs, such as: 1. Memory Management: It automatically handles the allocation and deallocation of memory, which helps prevent memory leaks. 2. Type Safety: The CLR ensures that objects are used in a manner consistent with their types, reducing the likelihood of runtime errors. 3. Exception Handling: It provides a robust framework for handling exceptions, which are errors that occur at runtime. 4. Security: The CLR enforces security policies that control how .NET code interacts with system resources and user data. 5. Interoperability: It allows .NET code to interact with non-.NET code, such as legacy Win32 applications. One of the key features of the CLR is just-in-time (JIT) compilation. When a .NET application is compiled, it is not turned directly into machine code that the CPU can execute. Instead, it is compiled into an intermediate language called Microsoft Intermediate Language (MSIL), also known as CIL. When the application is run, the CLR's JIT compiler translates this MSIL code into native machine code on the fly, which is then executed by the CPU. This process allows for optimizations that can improve the performance of the application. read more >>

The Common Language Runtime (CLR), the virtual machine component of Microsoft's .NET framework, manages the execution of .NET programs. A process known as just-in-time compilation converts compiled code into machine instructions which the computer's CPU then executes.read more >>
