I try to call parallel request it's working but if I added this line than not work parallel call.
System.Web.HttpContext.Current.Session["UserName"] = "dtest";
Any way to call parallel request with the session?
I was also facing same issue. Below solution helped me.
if (Context.Request.Path.Contains("xyz.svc"))
{
Context.SetSessionStateBehavior(SessionStateBehavior.ReadOnly);
}
Please try and check if this works.
