  1. POUnity framework DependencyAttribute only works for public properties?
    text
    copied!<p>I was trying to clean up some accessability stuff in my code, and inadvertently broke Unity dependency injection. After a while I realized that I marked some public properties that I didn't really want exposed outside my DLLs to internal. Then I started getting exceptions.</p> <p>So it seems that using the [Dependency] attribute in Unity only works for public properties. I suppose that makes sense since the internal and private props wouldnt be visible to the Unity assembly, but <em>feels really dirty</em> to have a bunch of public properties that you <em>never</em> want anyone to set or be able to set, other than Unity.</p> <p>Is there a way to let unity set internal or private properties too?</p> <p>Here is the unit test I'd like to see pass. Currently only the public prop test passes:</p> <pre><code> [TestFixture] public class UnityFixture { [Test] public void UnityCanSetPublicDependency() { UnityContainer container = new UnityContainer(); container.RegisterType&lt;HasPublicDep, HasPublicDep&gt;(); container.RegisterType&lt;TheDep, TheDep&gt;(); var i = container.Resolve&lt;HasPublicDep&gt;(); Assert.IsNotNull(i); Assert.IsNotNull(i.dep); } [Test] public void UnityCanSetInternalDependency() { UnityContainer container = new UnityContainer(); container.RegisterType&lt;HasInternalDep, HasInternalDep&gt;(); container.RegisterType&lt;TheDep, TheDep&gt;(); var i = container.Resolve&lt;HasInternalDep&gt;(); Assert.IsNotNull(i); Assert.IsNotNull(i.dep); } [Test] public void UnityCanSetPrivateDependency() { UnityContainer container = new UnityContainer(); container.RegisterType&lt;HasPrivateDep, HasPrivateDep&gt;(); container.RegisterType&lt;TheDep, TheDep&gt;(); var i = container.Resolve&lt;HasPrivateDep&gt;(); Assert.IsNotNull(i); Assert.IsNotNull(i.depExposed); } } public class HasPublicDep { [Dependency] public TheDep dep { get; set; } } public class HasInternalDep { [Dependency] internal TheDep dep { get; set; } } public class HasPrivateDep { [Dependency] private TheDep dep { get; set; } public TheDep depExposed { get { return this.dep; } } } public class TheDep { } </code></pre> <hr> <p>Updated:</p> <p>I noticed the call stack to set the property passed from:</p> <pre><code>UnityCanSetPublicDependency() --&gt; Microsoft.Practices.Unity.dll --&gt; Microsoft.Practices.ObjectBuilder2.dll --&gt; HasPublicDep.TheDep.set() </code></pre> <p>So in an attempt to at least make the internal version work, I added these to my assembly's properties:</p> <pre><code>[assembly: InternalsVisibleTo("Microsoft.Practices.Unity")] [assembly: InternalsVisibleTo("Microsoft.Practices.Unity.Configuration")] [assembly: InternalsVisibleTo("Microsoft.Practices.ObjectBuilder2")] </code></pre> <p>However, no change. Unity/ObjectBuilder still won't set the internal property</p>
