I follow the Mono Blog aggregator , and Miguel de Icaza mentioned that a user had tested ProMesh.NET on Mono , and it ran without any changes! That in in itself was cool, but when I took a look at ProMesh.Net , it looked like a well designed framework, perhaps comparable to MonoRail . The framework is ORM agnostic, and the biggest weakness might be it's view templates, but they have a great tutorial , so judge for yourself!
My experiences with computer programming, using c#, Mono, Ruby, Rails, SQL Server 2000, and MySQL.
