<p>Hello</p> <p>&nbsp;</p> <p>I have the following config:</p> <p>&nbsp;</p> <p> &lt;typeAliases&gt;</p> <p> &lt;typeAlias alias=&quot;singleton&quot;</p> <p> type=&quot;Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity&quot; /&gt;</p> <p> &lt;typeAlias alias=&quot;transient&quot;</p> <p> type=&quot;Microsoft.Practices.Unity.TransientLifetimeManager, Microsoft.Practices.Unity&quot; /&gt;</p> <p> &lt;typeAlias alias=&quot;IApplicationModule&quot;</p> <p> type=&quot;Framework.Interfaces.Snapin.IApplicationModule`1, Framework.Interfaces&quot;/&gt;</p> <p> &lt;/typeAliases&gt;</p> <p> &lt;containers&gt;</p> <p> &lt;container&gt;</p> <p> &lt;types&gt;</p> <p> &lt;!-- Internal Mapping: Module from the Framework.Common.dll assembly --&gt;</p> <p> &lt;type type=&quot;IApplicationModule&quot;</p> <p> mapTo=&quot;Framework.Common.Module, Framework.Common&quot; name=&quot;Module&quot;&gt;</p> <p> &lt;lifetime type=&quot;transient&quot; /&gt;</p> <p> &lt;/type&gt;</p> <p> &lt;type type=&quot;IApplicationModule&quot;</p> <p> mapTo=&quot;Framework.Common.Module2, Framework.Common.Tests&quot; name=&quot;Module2&quot;&gt;</p> <p> &lt;lifetime type=&quot;transient&quot; /&gt;</p> <p> &lt;/type&gt;</p> <p> &lt;/types&gt;</p> <p> &lt;/container&gt;</p> <p> &lt;/containers&gt;</p> <p>&nbsp;</p> <p>When I configure unity with this application file the Resolve(&quot;Module&quot;) or Resolve(&quot;Module2&quot;) successfully returns the modules. But when I do ResolveAll&lt;IApplicationModule&lt;MyType&gt;&gt;() then unity does not resolve the types and returns null instead. What am I doing wrong? It&#39;s really driving me crazy...</p> <p>&nbsp;</p> <p>When I manually register my types on the container with RegisterType&lt;IApplicationModule&lt;MyType&gt;, Module&gt;(&quot;Module&quot;) and RegisterType&lt;IApplicationModule&lt;MyType&gt;, Module2&gt;(&quot;Module2&quot;) ResolveAll works!! Is this an implementation bug?</p> <p>&nbsp;</p> <p>Thanks for your help</p> <p>&nbsp;</p> <p>Daniel</p>

    public override IEnumerable ResolveAll(Type t)
    {
        List names = new List(registeredNames.GetKeys(t));

        if (t.IsGenericType)
        {
            Type tdef = t.GetGenericTypeDefinition();
            names.AddRange(registeredNames.GetKeys(tdef));
        }

        foreach (string name in names)
        {
            yield return Resolve(t, name);
        }
    }
