    <p>I am trying to setup my object as remoting server. I use <code>RemotingServices.Marshal(myObj, uri)</code> for this. I have the following piece of code:</p> <pre><code>public class IpcRemoteObject : MarshalByRefObject { public void Register() { var channel = new IpcChannel("ipcSample"); ChannelServices.RegisterChannel(channel, false); RemotingServices.Marshal(this, "test", typeof(IpcRemoteObject)); Console.WriteLine("Created server, waiting for calls"); Console.ReadLine(); } } </code></pre> <p>If I call this from Main() of my program like below, everything works:</p> <pre><code>// case 1: works new IpcRemoteObject().Register(); </code></pre> <p>However, if I create the object in another AppDomain like below, I get "RemotingException: Requested Service not found" when connecting from clients.</p> <pre><code>// case 2: completes without error, but client connections fail var appDomain = AppDomain.CreateDomain("foo"); var remoteObj = (IpcRemoteObject)appDomain.CreateInstanceAndUnwrap(assembly, typename); remoteObj.Register(); </code></pre> <p>Then, if I create an intermediate class that makes call to Register() on my behalf and instantiate that class in another appdomain, everything is back to normal:</p> <pre><code>// case 3: works class Bootstrapper : MarshalByRefObject { public void Register() { new IpcRemoteObject().Register(); } } ... var appDomain = AppDomain.CreateDomain("foo"); var bootstrapper = (Bootstrapper)appDomain.CreateInstanceAndUnwrap( bootstrapperAssembly, bootstrapperType); bootstrapper.Register(); // works </code></pre> <p>So, here's the question: why <code>RemotingServices.Marshal()</code> does not work in case 2? Is there some kind of rule, or is it simply a bug in remoting? I am using .NET framework 4.5.</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.
