LayGO for C# has not yet been released.
It is possible to call LayGO API functions directly from a C# using P/Invoke. However, LayGO for C# provides a more object-oriented alternative for incorporating LayGO API access in C# applications. It is a collection of C# classes which encapsulate the main components of the LayGO Toolkit: the protocol stack, the protocol stack server and the protocol service connection identifier. It also includes a set of auxiliary classes for events, data and status and statistics information.
This manual describes the LayGO for C# classes and how to use them.
