C# 服务器-客户端实现与 TCP

Question

I want to create a simple messaging app that uses tcp protocol to communicate, including with multiple people. Messages get sent to the server, which distributes them to all other clients. At the moment, I have it fully functioning and it works perfectly - on a local computer and a local network, using the ipv4 address.

After an extensive Google search, I discovered that to communicate from a different network I need to port-forward my server. However, how do I make my server able to communicate with clients without all the clients port-forwarding? As far as I'm aware, not everybody's device is port-forwarded.

So, how do I implement this? Is it possible with just C#? Or did I misunderstand something, and port-forwarding isn't really required?

Thanks for all the help.

Why don't you use SignalR. I think it will be best for your problem.
