Is it possible to send and receive structs instead of classes ?

[genaray]

Well my question is pretty simple, i took a look into the documentation and saw examples on how you send and receive classes. But what about structs ? Can we send and receive those too without boxing them ?

What do you mean "send classes"? The data that Lidgren takes in is NetOutgoingMessage/NetIncomingMessage which you can fill in yourself, so there should be no problem filling it in with whatever struct data you have.
