Taking it further, Mono on the whole also enables easier migration - for both developers and users - from legacy CLR frameworks such as Microsoft.NET. Students who learn Visual Studio.NET at University can take their skills and directly apply them to creating or improving Free Software on their shiny new Ubuntu installations, without the need to learn a new language. Businesses with investment in .NET-based applications can look at replacing their servers or desktops with Free Software. Whilst providing .NET compatibility has always been a secondary goal, it is an extremely popular one, which has prompted a lot of input and development work from assorted people into the Mono codebase.
