Network programming C#, literature, tips?

Question

.NET

Hello.
Self-taught, I chose network programming as a direction and I have varying success. But all I know about the various mechanisms is my own ideas + googling related to the implementation of these ideas.
Hence the request to suggest sensible literature that describes the various mechanisms for network communication on Sharp.
For example, I build my protocols on top of the TCP transport, taking into account commands. And we got such a hybrid bike from a self-made ICMP specification (a hex-byte of a command with arguments) and an extended TCP \ IP specification (one packet = 64 bytes, the mechanism takes into account the assembly of all packets of one transaction). I am sure that such solutions have disadvantages, but without additional. knowledge I hardly see them.
Add. question: does it make sense to read additional. literature on mechanisms, or such an approach is sufficient and it is worth devoting time exclusively to studying theory and protocols.

I can advise you a couple of books if you have not read them yet, maybe you will learn something new for yourself.
On C#:
Network programming for professionals. Andrew Krovchik, Vinod Kumar.
And in general, about network programming, there are really examples in C, but you can figure it out:
Efficient TCP IP Programming. John Sneyd.
