Hi,
All available samples are located in Platform SDK Developer's Guide and Platform SDK API Guide. Please consider "Connecting to a Server" chapter of Platform SDK Developer's Guide.
The applications you write with the Platform SDK need to communicate with one or more Genesys servers, so the first thing you need to do is create connections with these servers. You will have to reference libraries and add using statements to your project for each specific protocol you are working with. These steps are not explicitly described here because the files and packages required will vary depending on which protocols you plan to use. Once you have connected to a server, you use that connection to exchange messages with the server.
