Hi Guys.I am developing a transport management system in wpf using mvvm pattern.Its a distributed software and i have heard that i would have to use Wcf.Are there any alternatives or is there any need of using Wcf?

You don't have to use WCF, you can develop your own methods of sending data using sockets, http, ftp, etc.

As Momerath said, you can use any pre-existing method of sending data over the wire. Just, WCF makes things a lot easier in terms of manipulation and you don't have to worry about network management.

You should investigate WCF at the least, but if you do, have a look at the WCF Web API. It might be easier for you to implement =)
