[FIXED] How to increase Message size in signal 2.2.2

Issue

I'm using signalr 2.2.2 to send the current html to a signalr server hosting process to convert to pdf and while doing that keep a progress bar shown on the client side. The issue is signalr has a max message limit of 64kb. How do I increase that? Below is my websocket transport trace log. The target and compilation .net framework is 4.5 so SignalR is using websockets for this.

transport trace log output:

Solution

The property you are looking for is MaxIncomingWebSocketMessageSize on GlobalHost.Configuration.
