SignalR hub not loading into Website if Hub having ref param API

We are having SignalR hub like,if we have API with ref or out param SignalR hubs are not loading in to Website,

If i removed this "ref or out" param type it working fine.

And I am getting the below error if i access "Signalr/hubs" in browser

Expression of type 'System.Int32&' cannot be used for parameter of type 'System.Int32' of method 'Int32 test(Int32 ByRef)'

Hub Code:

public class TestCommHub : Hub {

public void test(ref int intVal) { intVal = 0; }

}

Can anyone help to proceed this.

The methods you write in C# in the Hub class are supposed to be available to be called from JavaScript. That will be done though a JavaScript proxy. Most cases the generated proxy, unless you manually define yours. (about the proxy)

JavaScript will simply not understand the C# ref and out parameters.

However, SignalR will serialize your complex object parameters into JSON so you can use it in JavaScript.
