rest of init code Code language: C# ( cs ) Encapsulate the primitive parametersĬonsider encapsulating primitive parameters in a class. Youâd need to explicitly register this type and specify how to create it: //rest of adding services (_ => new JsonLogger( "web app")) Letâs say you have a class called JsonLogger with the following constructor: public JsonLogger( string source) Code language: C# ( cs ) If that type has a primitive constructor parameter, then also tell it exactly how to create the type. To solve this problem in our test automation, we came up with the. MassTransit fails to create Fault queue and messages get lost. Years ago, Chris Patterson of MassTransit fame explained something to me called the. MassTransit 4.0.1, Azure Service Bus, Autofac. Developers may want to do something with faults, such as updating an operational dashboard. Do NOT do this: builder.RegisterType ().As () Instead, as shown in the documentation, do this: x.AddConsumer () Your dependency can be registered as you've done it.Can you also reproduce the problem with the lastest version. Otherwise, the fault is published, allowing any subscribed consumers to receive it. You need to register the consumer as explained in the documentation. The simplest solution is to explicitly register the type. MassTransit fails in case of exception in a Consumer. Then Iâll show a few different variations of the problem. The error you get will depend on how youâre doing registration. ArgumentException: Cannot instantiate implementation type âType Nameâ for service type âType Nameâ.InvalidOperationException: Unable to resolve service for type while attempt to activate.If it canât resolve one of the parameters, itâll throw a variation of one of these exceptions: When the built-in dependency injection functionality is trying to create a type, it tries to resolve all of the constructor parameters.
