    <p>I am working on my MCTS and currently studying the AppDomain functionality. But I am running into something unclear. <code>AppDomain</code> should be capturing <code>Exception</code> and allow the domain to safely unload. (With the possible exception of the <code>StackOverflowException</code> as suggested elsewhere)</p> <pre><code>AppDomainSetup setup = new AppDomainSetup(); setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; Evidence adevidence = AppDomain.CurrentDomain.Evidence; domain.UnhandledException += new UnhandledExceptionEventHandler(domain_UnhandledException); AppDomain domain = AppDomain.CreateDomain("MyDomain", adevidence, setup); </code></pre> <p>When I decide to create an instance of the example class in an assembly I created for this purpose I should be getting a safe, restricted Domain which will capture errors that occur and can be safely unloaded. At least this is how I understand it from my study book.</p> <pre><code>var type = (IDoSomeWork) domain.CreateInstanceAndUnwrap("Library1", "Library1.Class1"); type.Run(); </code></pre> <p>This throws an exception however on <code>type.Run()</code> (since I made it that way). But shouldn't the <code>AppDomain</code> capture it safely? Isn't that why we have an <code>AppDomain</code>?</p> <p><strong>UPDATE:</strong></p> <p>As requested, I have included the definition of the <code>Library1.Class1</code>. Also, for clarity, the <code>UnhandledExceptionEventHandler</code> has no influence on capturing the exception and isn't relevant to the question.</p> <pre><code>[Serializable] public class Class1 : MarshalByRefObject, IDoSomeWork { public void Run() { Debug.WriteLine(AppDomain.CurrentDomain.FriendlyName); throw new ApplicationException(String.Format("{0}", this.ToString())); } } </code></pre> <p>I have verified that it runs in <code>MyDomain</code>.</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.
