Remarks
This generic class enables more advanced scenarios where there is a requirement to create a channel factory that can be used to create more than one type of channel.
Examples
'Initialize channel factory with a binding and a remote endpoint address.
Dim binding As New BasicHttpBinding()
Dim address As New EndpointAddress("https://localhost:8000/ChannelApp")
Dim factory As New ChannelFactory(Of IRequestChannel)(binding, address)

Dim epa As EndpointAddress = channel.RemoteAddress
Dim via As Uri = channel.Via
Dim request As Message = Message.CreateMessage(MessageVersion.Soap11, "hello")
Dim reply As Message = channel.Request(request)
Console.Out.WriteLine(reply.Headers.Action)
reply.Close()
channel.Close()
factory.Close()
