    <p>when you load an assembly into the AppDomain in that way, it is the <em>current</em> AppDomain's PrivateBinPath that is used to find the assembly.</p> <p>For your example, when I added the following to my App.config it ran fine:</p> <pre><code>&lt;runtime&gt; &lt;assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"&gt; &lt;probing privatePath="[PATH_TO_PLUGIN]"/&gt; &lt;/assemblyBinding&gt; &lt;/runtime&gt; </code></pre> <p>This is not very useful to you though.</p> <p>What I did instead was to create a new assembly that contained the IPostPlugin and IPluginsHost interfaces, and also a class called Loader that looked like this:</p> <pre><code>public class Loader : MarshalByRefObject { public IPostPlugin[] LoadPlugins(string assemblyName) { var assemb = Assembly.Load(assemblyName); var types = from type in assemb.GetTypes() where typeof(IPostPlugin).IsAssignableFrom(type) select type; var instances = types.Select( v =&gt; (IPostPlugin)Activator.CreateInstance(v)).ToArray(); return instances; } } </code></pre> <p>I keep that new assembly in the application root, and it doesn't need to exist in the plugin directories (it can but won't be used as the application root will be searched first). </p> <p>Then in the main AppDomain I did this instead:</p> <pre><code>sandbox.Load(typeof(Loader).Assembly.FullName); Loader loader = (Loader)Activator.CreateInstance( sandbox, typeof(Loader).Assembly.FullName, typeof(Loader).FullName, false, BindingFlags.Public | BindingFlags.Instance, null, null, null, null).Unwrap(); var plugins = loader.LoadPlugins(AssemblyName.GetAssemblyName(f.FullName).FullName); foreach (var p in plugins) { p.Init(this); } _PostPlugins.AddRange(plugins); </code></pre> <p>So I create an instance of the known Loader type, and then get that to create the plugin instances from <em>within</em> the plug-in AppDomain. That way the PrivateBinPaths are used as you want them to be.</p> <p>One other thing, the private bin paths can be relative so rather than adding <code>d.FullName</code> you could add <code>pluginsDir + Path.DirectorySeparatorChar + d.Name</code> to keep the final path list short. That's just my personal preference though! Hope this helps.</p>

    1. COJames, thank you very much! Finally I see the clear explanation about using MarshalByRefObject. Unfortunately I haven't enough reputation to mark an answer as useful (need at least 15) :(

    3. COWhen I try this, although I made the LoadPlugins-method generic, I get a SerializationException. Any suggestions as to why that may be? I can see that the assembly has been loaded in the sandbox app domain.

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.
