IWebCF provides a platform for developers to extend DotNetNuke using WCF services. IWebCF brings the power of SOA to DotNetNuke, allowing DNN to be more easily integrated with enterprise applications and services.
IWebCF is the next generation of the original IWeb module for DotNetNuke. IWeb originally was developed using the classic ASMX web services and allowed extension methods to be added very easily. File management extension methods were added to the module and
a file manager client was also included. IWebCF picks up at this point and migrates the underlying technology to WCF and away from ASMX web services.
