    <p>It's a slightly confusing topic, so here's a step-by-step example - now using the names from Eric's answer to help keep things consistent. We're going to start off with one library (Alpha.dll) and build an application (Test.exe) which depends on Alpha. We're then going to a type which Test.exe depends on (Foo) into a different library (Bravo.dll) without recompiling Test.exe.</p> <ol> <li><p>Create the following files:</p> <p><strong>Foo.cs</strong></p> <pre><code>using System; public class Foo { public static void Report() { Console.WriteLine("Foo.Report"); } } </code></pre> <p><strong>Test.cs</strong></p> <pre><code>class Test { static void Main() { Foo.Report(); } } </code></pre></li> <li><p>Build Alpha.dll:</p> <pre><code>csc /target:library /out:Alpha.dll Foo.cs </code></pre></li> <li><p>Build Test.exe</p> <pre><code>csc /r:Alpha.dll Test.cs </code></pre></li> <li><p>Run Test.exe - you should get the obvious output</p></li> <li><p>Build Bravo.dll:</p> <pre><code>csc /target:library /out:Bravo.dll Foo.cs </code></pre></li> <li><p>Create a new file, <strong>Forwarding.cs</strong>:</p> <pre><code>using System.Runtime.CompilerServices; [assembly:TypeForwardedTo(typeof(Foo))] </code></pre></li> <li><p>Recompile Alpha.dll:</p> <pre><code>csc /r:Bravo.dll /target:library /out:Alpha.dll Forwarding.cs </code></pre> <p>Note how we're <em>not</em> including the code for Foo in Alpha any more.</p></li> <li><p>Run Test.exe - it will still work, despite the fact that Test.exe <em>asks</em> for a reference to Foo within Alpha.dll... the CLR simply redirects that to Bravo.dll.</p> <p>If you look in Test.exe, it will still refer to Alpha. If you look in Alpha.dll, you'll find that the code for the Foo type isn't there any more... it's only through type forwarding that it all hangs together.</p></li> </ol>

    1. COBTW, thanks Jon for the great example. I was really after the "Type" part of the "Type Forwarding". I understand it now.

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.
