Hi, Mainly the NGen.exe will be used at the time of .net application installation. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local computer. The runtime can use native images from the cache instead of using the just-in-time (JIT) compiler to compile the original assembly . Its nicely explained here .
