What are the steps to incorporate SignalR into a TypeScript project?

Working on an asp.net mvc 4.5 project with typescript in the client side, I successfully installed and configured signalR on the server side. To integrate it into my project, I also installed signalr.TypeScript.DefinitelyTyped with jquery.

In my typescript file, I referenced signalr like this at the top: ///

Additionally, I created an interface file for my hub:

interface SignalR {
    ForecastHub: {
        client: {
            DeleteProject(projectId: number)
        };
        server: {
            send(name: string, message: string)
        };
    };
}

The main implementation code in my typescript file is as follows:

var client = $.connection.ForecastHub;
client.client.DeleteProject = function (projectId) {
    alert(projectId);
};

$.connection.hub.start().done(function () {
});

During runtime execution, I encountered an error stating 'Cannot read property 'ForecastHub' of undefined'. This led me to search for a solution on how to correctly import signalr in typescript. If you have any suggestions on how to seamlessly integrate signalR in a typescript project, please provide your insights. Thank you!
