It is becoming more and more obvious that there are just two runtimes left to execute code, the Java Virtual Machine (JVM) and the Common Language Infrastructure (CLI). So, I decided to see how they stack up. Looks like both environments have something for everyone. Here is a list of programming languages available on these runtimes. Can run on CLI using IKVM.NET Can run on JVM using Mainsoft solution Not yet usable Can run on CLR, but is behind the JVM implementation The main reason for the research was to identify a new language I should pick-up.
