Re: Thinking about driving from South Africa to Tanzania. Jan 29, 2013, 5:40 AM. good to hear. right now we are in SA and are thinking to make our way up to Tanzania for Safari in Mid-March (departing SA beginning of February). That would make about 6 weeks of driving.
To summarize, C# programming language can be used to build Windows app using the .NET platform, and can also be used to build Linux app using the Mono platform. It cannot be used to make an Android app, but with persistence, in theory, you can wrap it around the Android NDK framework.
C# is compiled into Common Intermediate Language, which is then run by the Common Language Runtime part of the .NET framework, an environment that supports just-in-time compilation. The speed of C# and Java is almost as fast as true compiled language. As far as speed goes, C, C++ and C# all are sufficiently speedy for games and operating systems.
