Messages from WebSocket4Net to server arrive fragmented

[nicolasr75]

I want to send some JSON content from a C# client to an ASP.NET Core server. As my message size increased I suddenly noticed that the receiving JSON parser fails on almost every message because the original JSON strings get broken up into multiple messages. What is the solution for this problem?

• is it my task to create sort of a frame around my JSON string so that the receiver can buffer it and only parse complete JSON strings?
• should I increase the send buffer size? But WebSocket4Net doesn't seem to allow me change the buffer size
• is WebSocket4Net limited to small messages and I have to break up my messages into multiple smaller but valid JSON strings?

It is not supposed. If you can leave some code which can reproducet this issue, that would be great.

Ok, that's good to know. Do you think it may be a problem of the receiving ASP.NET Core server? I maybe should check with Wireshark where the data get broken up. My application is already quite large, I will see if I can create a smaller project and show the code.
