How to use Postal with Unity IoC Container MVC 5?

[haseebIC]

I am having trouble with Postal setup. I have registered dependencies like below:

container.RegisterType<IEmailParser, EmailParser>(); container.RegisterType<IEmailViewRenderer, EmailViewRenderer>(); container.RegisterType<IEmailService, EmailService>();

On the controller side I have the following code:

private readonly IEmailService _emailService;

public EmailsController(IEmailService emailService)
{
this._emailService = emailService;
}

public ActionResult Test()
{
var email = new TestEmail
{

        };
        var message = _emailService.CreateMailMessage(email);
        return new EmailViewResult(email);

}

The dependencies are being injected properly by the unity container but the target view ("Test") is not being found by ViewEngine.

However, when I have the following code in the controller everything works fine.

private readonly IEmailService _emailService = new EmailService(ViewEngines.Engines);;

public ActionResult Test()
{
var email = new TestEmail
{

        };
        var message = _emailService.CreateMailMessage(email);
        return new EmailViewResult(email);

}

I believe I'm doing something wrong while registering the unity container. Please help me out.

Thanks

Try registering IEmailService with a factory method that injects ViewEngines.Engines explicitly, like this: container.RegisterType(new InjectionFactory(c => new EmailService(ViewEngines.Engines)));. This Solution should ensure that the ViewEngines are passed properly during injection.
