Question

Is there a way for a unity container to pass itself to an object?

i.e.:

public class Something {

     public Something(IUnityContainer container) {
           ...
     }
}

Answer 1

The short answer is yes.

This should be passed automatically when you use the Resolve methods.

For example:

IUnityContainer container = new UnityContainer();
var something = container.Resolve<Something>();

Additionally, this is the same technique that Prism (on CodePlex) uses if you want to look into that.

Update Added Test:

[TestClass]
public class Spike
{
    [TestMethod]
    public void unityTest()
    {
        var container = new UnityContainer();
        var something= container.Resolve<Something>();
        Assert.AreSame(container, something.Container);
        // This passes. Success.
    }
}

public class Something
{
    public Something(IUnityContainer container)
    {
        Container = container;
    }

    public IUnityContainer Container { get; set; }
}
