  Hi,

  Normally, interceptors (unit of work, authorization, validation) automatically work when you call an application service method and you shouldn't need to use them directly. Can you write your purpose and use case for a better help?

  Halil,

  In context, there is an interceptor to apply parameters to a data filter based on the user context. Everything in the WebAPI works well, but file download via WebAPI is not really great, so we created an MVC action. In order to ensure/enforce proper security, the data filters must be set. We could certainly apply them manually in the controller action, but the thought was to get part of the record through the AppService pipeline in hopes it would be automatic.

  public ActionResult Download(int recordId)
  {
    var record = _appService.Get({id = recordId}); // Interceptor is not hit
    var pdf = renderPdf(record);
    return File(pdf);
  }
  

  I tried to look through the code to see how the interceptor is executed, but I did not find anything obvious. I presume it is registered somewhere in the IocManager, but never found it.

  Thanks, Jeff

  Hi,

  Are you sure that you have injected your application service via it's interface (not concrete class)? If it's required to inject by class, then you need to make your app service method virtual, otherwise dynamic proxy can not work.
