I need to take a moment to thank the DotNetNuke Project and User community for providing an excellent ecosystem for keeping up with technology.
It is truly amazing to see DotNetNuke keep up with the latest releases from Microsoft across the board for IIS, ASP.NET, SQL Server, and the many API's coming out of Redmond.
You certainly do not need to worry about being left behind with technology when choosing DNN as Web Framework. I have seen DNN be there day one for the releases on VS 2005 and ASP.NET 2 as well as the release of VS 2008. You know that DNN will have downloads available almost immediately VS 2010 and ASP.NET 4 are released.
And the same can be said for the core technologies that Microsoft releases.
· OpenID
· Linq To SQL
· Silverlight
· Dynamic Data
· Live API’s
I was lucky enough to be involved with of the DNN teams and projects and was very excited to see them embrace concepts such as Test Driven Development and incorporating their own Container for assigning Concrete classes to required interfaces in a flexible manner. They are supportive of other open source technologies such as Subsonic and you can almost always find someone else working on a solution to an issue in the forums for newer technologies.
So do not be afraid of being left behind and having trouble with support for existing or new technologies. The DotNetNuke Framework and Corporation will not let you down!
