If you purchased the module with the source code, i.e. "Enterprise Version with Code", please keep in mind that the ZIP file contains both the PA and the source code.
If you wish to develop the source code do not install the PA. It causes some kind of DLL conflict. If you installed it before, we recommend to uninstall it first.
Sample Source Code
The code is constructed and organized just the way DNN team recommends. We provided source blocks with the same naming conventions of the "C# Template" of DotNetNuke.
Also the variable names and methods are easy to interpret and the code is clean.
