The Native Image Generator (Ngen.exe) is a tool for the .NET framework that improves the performance of managed applications by creating and caching processor-specific machine code, so that just-in-time compilation is no longer necessary.

From Native Image Generator (Ngen.exe) on MSDN:

The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. 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 using the just-in-time (JIT) compiler to compile the original assembly.

Is it possible to "ngen" an executable on a network drive?

The title speaks for itself. To clarify things: so far I've used Ngen in an installer to compile the .exe with all dependencies which gave us a huge speedup, be it at startup or at runtime (at least it feels like so). But now I wanted to create an…
