The NetXtremeScp .NET class library offers a number of classes that make the work of transferring files directly from your application using SCP more easily. ScpClient class provides a number of convenience asynchronous methods and events that allow you to quickly create applications which can handle file transfers simultaneously. The library also offers the flexibility, ease of use and rapid development features of a component without the complexities of working with the native socket class or in-depth knowledge of how the SCP is implemented.
