We will conclude with a discussion on some related tools like ILASM, ILDASM, NGEN, etc, that ship with the Micorosft.NET Framework SDK. The Microsoft Intermediate Language Assembler or the ILASM tool is used to package the MSIL code and store it in a file in the Portable Executable (PE) format. The Microsoft Intermediate Language Disassembler or the ILDASM tool is used to retrieve the MSIL code from a PE file. According to MSDN, "the MSIL Disassembler is a companion tool to the MSIL Assembler (Ilasm.exe). Ildasm.exe takes a portable executable (PE) file that contains Microsoft intermediate language (MSIL) code and creates a text file suitable as input to Ilasm.exe." The Native Image Generator or the NGEN tool is used to generate native code from the MSIL code.
