NGen is good in some cases but it can hurt load time and/or run time performance in other cases. It does not make much sense for server side apps. For client apps, it may make sense if the app calls thousands of methods before GUI starts or for assemblies that have few references (because CLR won't need to load the JIT compiler).

Hope this helps,

Microsoft's Winforms dll is not ngened by default. Precompiling Windows Forms applications usually results in a performance win. You can choose to run ngen.exe during install time or before you distribute you application. I will recommend you to run ngen.exe during install time, because the application will be optimized for the machine on which it is being installed. If you run ngen.exe before you distribute the application, you limit the optimizations to the ones available on your machine.
You can read more about the ngen.exe on this site:

I'd suggest not to NGen all of your assemblies with the hope to gain significant performance. In reality, JIT compilation is very optimized and can produce excellent speed -- except for the first time. As I mentioned previously, NGen is suitable only in a few situations.

Hope this helps,
