If multiple versions of.NET exist on a system in “C:WindowsMicrosoft.NETFramework”, such as “… v2.0.50727” and “… v4.0.30319”, each will have its own “ngen.exe” and “mscorsvw.exe” executable files. Originally, (since.NET Framework 1.0 before 2005), through Win7, “mscorsvw.exe” ran “ngen.exe” to compile the entire.NET library to machine code, which caused heavy CPU usage.
