Commands are processed against the domain model (DDD style), the domain model will raise events that are then persisted in an event store, and the events are published on an event bus. At this point, assuming nothing went wrong in the command handler, the command handler will send a response back to the client. The problem was that my UI would time out, but I could also see that nothing went wrong in my command handler since I can see the events being propagated to the event bus. There were no exceptions being thrown or swallowed by the command handler - it was all working, and yet I was not recieving the response back in the UI. I checked out the MassTransit Google Group and discovered that an issue had been reported with Request/Response in ASP.NET - I am hosting my Nancy UI in ASP.NET - so this got me thinking that this was my problem, even though it was reported as fixed in v2.7 of MT. Now I am thinking that I am doing something wrong. The next thing to do was to write a really simple Nancy UI and a really simple command handler service communicating via MassTransit. The UI sends a request and the command handler echos it back. I go back to my original solution and decide to debug the Nancy UI, turn on exceptions break where thrown. Specifically an exception thrown by the NewtonSoft Json serializer - it can't deserialize my message. ![]() A little more digging and I find out that I am not setting all the fields on the response message withing the command handler before sending it back to the UI. When that response arrives at the UI, the Json serializer can not find the unassigned fields - it thinks they are missing - and pukes. ![]() Now MassTransit does not give you any indication that there was a problem, it just doen't call your delegate that it is supposed to call when a message arrives. No exceptions, no other delegate to let you know there was a message deserialization problem, nothing. And this is the documented behaviour - MT will not call you back if there is it can not handle the message.Īs soon as I fixed the command handler to fill in all fields with default values before sending it back to the UI, the system works as expected - I get the response back in the UI and no more timeouts.In this post, I want to set up MassTransit with RabbitMq and. My application already uses AutoFac as a DI container, that I will take advantage of in this post. All the information to get MassTransit setup is out there but it is spread across the documentation, GitHub issues, StackOverflow and all the other usual places. I want to bring the information I needed to get it working together in one place. There will be 2 services that will communicate together across the bus. The 1st will be an API, and the Second will be a Service for application logic, working with a DB or whatever you want it to do. We will set up a Ping Controller in the API that will dispatch a command to the service via MassTransit. The Service will then take the command off the bus and consume it, before publishing an Event indicating that the Ping was consumed. The API will subscribe to this Event and listen for it before returning a synchronous result that includes the time that the process took. ![]() Looking back at it there isn’t a lot involved to configure a basic setup of MassTransit. There was only one gotcha, that probably should be included in the. Net core setup guide but as usual, the answer was found on StackOverflow.įor. Net Core, there are a few ways of configuring MassTransit.
