We also have a Save method that we will call from our controller (coming soon).

Building systems is a constant series of trade-offs. In that case, you will have to decide whether the requirement to display the ticket ID immediately to the user is worth a round-trip to the ticketing system to get it.

When the rubber meets the road, however, you may be integrating with a ticketing system that wants to assign it’s own IDs. Remember, the reason we’re using a service bus is to have this web application loosely coupled to whatever backend is used for our ticketing system. The point to remember is that we need a way to generate an identifier that we know should be unique in whatever data storage repository we will be storing the tickets in without having to consult said data storage repository. They aren’t a great user experience, of course, due their length. GUIDs work well for this in terms of being easy to implement for a developer, as it’s a single line of code. X.SetDeliveryMode() īecause we want to be able to tell the user what their ticket ID is right away, we need some method to generate a statistically unique, random ID.

Open and make sure the code looks like this: using The best place I’ve found to create and configure MassTransit in an ASP.NET app is in the Global.asax’s Application_Start event handler. Also, add the MassTransit NuGet package to the project. Returning to the in our solution, right-click on References and add project references to the and projects. In summary, we’re setting up a new instance of a MassTransit service bus that will use RabbitMQ for it’s transport mechanism. In that earlier post I describe what we’re doing here in detail. The only thing we’ve changed is the prefix for the queue name. You may recall, in a previous post, when we did the same thing. X.ReceiveFrom("rabbitmq://localhost/Loosely_" + queueName) Public static IServiceBus CreateBus(string queueName, Action moreInitialization) We’ll put the common service bus initialization code into a class called BusInitializer: using MassTransit

Add the MassTransit.Log4Net and MassTransit.RabbitMQ NuGet packages to this new class library. Now let’s add another class library named “” where we’ll keep our common MassTransit configuration code. This is the message type we will publish onto the service bus whenever a user of the web application wants to open a new support ticket. Add a new class library to the solution and name it “.” Add a new file to the class library called TicketOpened and define the following interface: namespace A contract is an interface that specifies the format of our message type. Now we need a place to keep our “contracts” for our service bus. In the “New ASP.NET Project” select the “Empty” template and check the “MVC” box under the “Add folders and core references for” heading. Give it the name “” and name the solution “Loosely.CustomerPortal.” Select the “ASP.NET Web Application” project template. Open Visual Studio and choose File… New Project. So let’s dig into the code to build this web app. When the user clicks “Open Ticket,” they will see a confirmation message containing their ticket number: When the user clicks “Open a new support ticket,” they will get a very simple form asking for their email address and a description of their problem or question: We’ll build an app that has a single menu option on it’s home page: Let’s build a rudimentary front-end application that will be a stand-in for a true customer portal style web site. This is a big one, so roll up your sleeves… The Web App You can get all the code from this blog post at.

We’ll create a Windows Service to be the subscriber of these messages and it will handle the tickets, in this example, sending a confirmation email to the customer. The ticket will be published onto the service bus. In this article, we’ll build an ASP.NET MVC Customer Portal app where a customer can create a new support ticket.

Now that we’ve seen some simple examples of how to use MassTransit with the Publish/Subscribe pattern on multiple machines, let’s build something that resembles a more real-world app.
