What is the role of the JIT compiler in. NET Framework?

Explanation

  • The JIT compiler is an important element of CLR, which loads MSIL on target machines for execution.

  • MSIL is stored in. NET assemblies after the developer has compiled the code written in any. NET-compliant programming language, such as Visual Basic and C#.

  • JIT compiler translates the MSIL code to CPU architecture of the target machine to execute a. NET application.

  • It also stores the resulting native code so that it is accessible for subsequent calls.

  • If a code executing on a target machine calls a non-native method, the JIT compiler converts the MSIL of that method into native code.

  • JIT compiler also enforces type-safety in runtime environment of. NET Framework- checks values that are passed to parameters of any method. For example, JIT compiler detects if a user tries to assign a 32-bit value to a parameter that can only accept 8-bit value.
