The samples folder includes a simple server for use with those samples that require one. The following samples require a server in order to run:

When the host sample initiates communication with the samples server, it sends the sample server a code that tells the server which sample is connected. The server then starts the specific flow for the sample, returns the requested data, and then listens for additional messages.

For details of how the server and the samples interact, see the page describing the specific sample.
