how to use SignalR with multiple VS projects RRS feed

    Whenever data in a SQL table changes I want to use SignalR to show the changes immediately on my user interface (Asp.NET MVC EF6).  So I started researching and found the article below on codeproject.com.  My solution is a little different though because I have multiple projects (WEB, DATA- this project has my repositories, migrations, unit of work, DbContext, etc., SERVICE, MODEL).  In my DATA project I added the repository similar to the example but where I'm stuck is the SQL dependency OnChange method because my Hub is in my web project.  Do I pass the Hub from the web project to the service/repository?  I don't think it makes sense to add SignalR NuGet package to my DATA project.  Can anyone give me some pointers?

    The data access project is either a DLL in the web application or a DLL in a service.  Basically, your question is irrelevant because the executing code is in the web or service project.

    Here is my problem.  I have this code in my repository.  MessagesHub does not exist in my repository (DATA) project.  It only exists in the WEB project.  How can I make it work?

            private void dependency_OnChange(object sender, SqlNotificationEventArgs e)
                if (e.Type == SqlNotificationType.Change)
                    //I get an error here because MessagesHub does not exist.  The Hub is inside my web project.  How do I fix this?
