What is the solution for TCP Zero Window in C#?

Question

Hi Friends,

I need your help.

There is two application A and B communication over ethernet using TCP socket.

After 3 hours application A sending "TCP Full Window" to application B.

And then  application B sending "TCP Zero Window" to application A.

 

Then onwnrds there is no data transfer between applications only "TCP Zero Window" showing on wireshark.

 

 

Thanks in advance.
