This project is based on the Hangfire.Unity project with 2 chnages

• Hangfire.Unity works fine for Unity v5+ but due to namespace changes you can't use it for Unity v4. This package (Hangfire.Unity4) works with old namespace of unity which is Microsoft.Practices.Unity
• This package also have a helper class for lifetime management called PerRequestOrHierarchicalLifeTimeManager which if you don't have HttpContext available, it will offer HierarchicalLifetimeManager instead of PerRequestLifetimeManager you can use this to in RegisterTypes method to avoid Resolve exception

public static void RegisterTypes(IUnityContainer container)
{
    container.RegisterType<IMyService, MyService>(new PerRequestOrHierarchicalLifeTimeManager());
}

Hangfire background job activator based on Unity IoC Container. It allows you to use instance methods of classes that define parametrized constructors:

public class EmailService
{
	private DbContext _context;
    private IEmailSender _sender;
	
	public EmailService(DbContext context, IEmailSender sender)
	{
		_context = context;
		_sender = sender;
	}
	
	public void Send(int userId, string message)
	{
		var user = _context.Users.Get(userId);
		_sender.Send(user.Email, message);
	}
}	

// Somewhere in the code
BackgroundJob.Enqueue<EmailService>(x => x.Send(1, "Hello, world!"));

Improve the testability of your jobs without static factories!

Hangfire.Unity4 is available as a NuGet Package. Type the following command into NuGet Package Manager Console window to install it:

Install-Package Hangfire.Unity4

The package provides an extension method for OWIN bootstrapper:

app.UseHangfire(config =>
{
    var container = new UnityContainer();
	// Setup your unity container
	
	// Use it with Hangfire
    config.UseUnityActivator(container);
});

In order to use the library outside of web application, set the static JobActivator.Current property:

var container = new UnityContainer();
JobActivator.Current = new UnityJobActivator(container);
