Hello,
I'm new to the DotNetNuke framework and have a few simple questions. I will be developing a rather large portal application in C# and I'm wondering how I should view DNN? Should I modify DNN core code as needed or should I develop custom .ascx files and try to inherit from DNN's framework??? Any suggestions would be greatly appreciated.

Thank you,
JW

Modifying the core will make future upgrades hard or impossible to do without remaking the core changes in the new source.

Custom modules is the way to go.

Hi JW,

Welcome to DotNetNuke!

The DotNetNuke portal core framework is very powerful, flexible and extensible. You can greatly enhance the capabilities of a DNN portal by creating custom modules in any .Ne language of your choice. My suggestion is to leave the core untouched to the extent possible and use modules, providers and skins to add/enhance your portal as needed. If you change the core, upgrades become more complicated and you increase the probability that third-party modules, providers and skins will become incompatible with your portal.

Thank you much all. I do appraciate the advice and plan to follow it. I'm sure you will hear from me often in the days to come :-)
