Name
Ngen.exe — Native Image Generator
Synopsis
ngen [options
] [assembly-path-or-display-name
...]
Description
Compiles an assembly to native code and installs a native image in the local computer’s native image cache. That native image is used each time you access the original assembly, even though the original assembly contains MSIL. If the runtime can’t locate the native image, it falls back on JIT compilation.
Examples
ngen foo.exe ngen foo.dll
