I always wanted to try out coding C# application on Ubuntu Linux. The most popular IDE of choices for this would be MonoDevelop by Mono Project. I installed MonoDevelop through Synaptic the same way I did with other applications.
It was a surprise to me to found out that Mono even supports some new features from of C# such as Lambda Expression and Object Initializer!
The only problem is their IDE, MonoDevelop, still not support autocompletion (a.k.a. Intellisense) of Lambda Expressions and Object Initializers. Moreover, it marks the code as error by underlining them in red.
In conclusion, Mono looks promising. And I just can't wait to see more Linux people coding new apps in C#!
