Since 2002, the first release of DotNetNuke VB.NET (Visual Basic) was the first core development language of DotNetNuke Framework. Then, C# Developers started to publish their own free or paid extensions for DotNetNuke. Many people asked about a path to convert DNN's VB.NET interface into C# programming language.
Well, this is the day the official announcement has been made. DotNetNuke 6 will include C# source code. Hurray!!!
Obviously this was the right decision, because C# is more popular than VB.NET nowadays and clients asking about C# source code for modules and even DNN Core. Shaun states that a community preview version of DotNetNuke 6 will be published in Q2 of 2001 in order to attract DotNetNuke Developers and of course C# programmers. I think Feb 2011 was a great milestone for DotNetNuke Community to hear such a great announcement. Guess what? Combine it with Active Modules Forum integration. Than you'll have a great CMS + Source Code.
