Compiler in framework

Question

Hi... I want to know, how many compiler in a framework ? Please tell me anyone ? Thanks.....

As well as the JIT compiler (which is part of the CLR) a number of language compilers are provided as part of the .NET framework. These compile source code of the languages concerned into MSIL and metadata. As of .NET 4.0 they include compilers for the following languages: C# (csc.exe) VB.NET (vbc.exe) JScript (jsc.exe) IL (ilasm.exe) Although Visual Studio 2010 also supports development in F# and C++/CLI these compilers are not technically part of the framework.

Hi Vineet, One is JIT JIT (Just - In - Time) is a compiler which converts MSIL code to Native Code (ie.. CPU-specific code that runs on the same computer architecture). Because the common language runtime supplies a JIT compiler for each supported CPU architecture, developers can write a set of MSIL that can be JIT-compiled and run on computers with different architectures. However, your managed code will run only on a specific operating system if it calls platform-specific native APIs, or a platform-specific class library. JIT compilation takes into account the fact that some code might never get called during execution. Rather than using time and memory to convert all the MSIL in a portable executable (PE) file to native code, it converts the MSIL as needed during execution and stores the resulting native code so that it is accessible for subsequent calls. The loader creates and attaches a stub to each of a type's methods when the type is loaded. On the initial call to the method, the stub passes control to the JIT compiler, which converts the MSIL for that method into native code and modifies the stub to direct execution to the location of the native code. Subsequent calls of the JIT-compiled method proceed directly to the native code that was previously generated, reducing the time it takes to JIT-compile and run the code.
