// Function Description:
// - Create an instance of the connection specified in the
// ConnectionInformation, and Initialize it.
// - This static method allows the content process to create a connection
// from information that lives in the window process.
// Arguments:
// - info: A ConnectionInformation object that possibly lives out-of-proc,
// containing the name of the WinRT class we should activate for this
// connection, and a bag of setting to use to initialize that object.
// Return Value:
// - <none>
