    <p>I have an application that uses <a href="http://www.castleproject.org/projects/dynamicproxy" rel="nofollow">DynamicProxy</a> 3.1 to do runtime interception. I have a test assembly that uses <a href="https://github.com/nsubstitute/NSubstitute" rel="nofollow">NSubstitute</a> for mocking. I just wrote some "integration" tests against my fully bootstrapped container (StructureMap using <code>InterceptWith</code> to do the interception) so that I can assert that certain types coming out of the container are proxied properly.</p> <pre><code>[Subject(typeof(RobotBoard))] public class When_resolving_an_intercepted_type : WithContainer&lt;IRobotBoard&gt; { It should_have_recovery = () =&gt; Subject.ShouldHaveInterceptor&lt;RecoveryInterceptor&gt;(); } public static class TestExtensions { public static void ShouldHaveInterceptor&lt;T&gt;(this object obj) where T : IInterceptor { ((IProxyTargetAccessor)obj) .GetInterceptors() .ToList() .Exists(x =&gt; x is T) .ShouldBeTrue(); } } </code></pre> <p>However, I get this error, indicating that DynamicProxy references are <em>inside</em> the NSubstitute assembly, too! (it appears to be ilmerged).</p> <pre><code>Error 11 MyCompany.MyModule.Specifications D:\code\source\tests\When_resolving_an_intercepted_type.cs The type 'Castle.DynamicProxy.IProxyTargetAccessor' exists in both 'd:\code\packages\Castle.Core.3.1.0\lib\net40-client\Castle.Core.dll' and 'd:\code\packages\NSubstitute.1.4.2.0\lib\NET40\NSubstitute.dll' </code></pre> <p>Is there anyway around this conflict?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
