Unity job activator for Hangfire

Hangfire.Unity

This project is based on the Hangfire.Ninject project.

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!
