[Freeswitch-dev] How to create extensions programmatically through .net ?

I have recently setup the fusionpbx server with freeswitch and my scenario is off a mobile app registration which triggers a creation of an extension.My backed logic is based on .net framework. Can anyone direct me whether this can be done using Freeswitch.Managed.dll or it is simply done via web api?? Thanks again -- *Regards,* Nezam Uddin
