    <p><em>I'll leave this answer here for future reference, but I like my <a href="https://stackoverflow.com/questions/5026711/possible-getobjectsoftype-replacement/5156853#5156853">other answer</a> better.</em> </p> <p>The original answer is rather lenghty and very specific to the example in the question. </p> <p>I don't think there is a configuration equivalent to <code>GetObjectsOfType(...)</code>.</p> <p>However, isn't it very easy to get rid of the Spring.net dependency?</p> <p>Let me see if I understand correctly:</p> <pre><code>// sharedLib contains ICustomInterfaceThatDoesSomething // by "--&gt;" I mean "depends on" webApp --&gt; Spring.Core, Spring.Web webApp --&gt; sharedLib sharedLib --&gt; Spring.Core // only to call GetObjectsOfType(...) on Spring container </code></pre> <p>We want to get rid of the last dependency, because we want to be able to use <code>sharedLib</code> in combination with another DI container. In <code>sharedLib</code> we have a class that needs to signal all <code>ICustomInterfaceThatDoesSomething</code> implementations to do something. For this purpose I'd create:</p> <pre><code>MySomethingManager { public MySomethingManager() {} public MySomethingManager(IMySomethingDoerProvider prov) { // init SomethingDoers } IList&lt;ICustomInterfaceThatDoesSomething&gt; SomethingDoers { get; set; } void SignalAllToDoSomething() { foreach (var doer in Provider.SomethingDoers ) doer.DoSomething(); } } IMySomethingDoerProvider { IList&lt;ICustomInterfaceThatDoesSomething&gt; GetAll(); } </code></pre> <p><code>MySomethingManager</code> used to contain the Spring dependency, but now it's Spring Free. Now I have two options when wiring up <code>sharedLib</code> with regard to <code>MySomethingManager</code>:</p> <ol> <li>using property injection on <code>MySomethingManager.SomethingDoers</code> with a <code>List&lt;ICustomInterfaceThatDoesSomething&gt;</code></li> <li>using constructor injection with an <code>IMySomethingDoerProvider</code> implementation</li> </ol> <p>Both can be done using Spring and many other DI containers. You can use the first approach if you don't mind listing all <code>ICustomInterfaceThatDoesSomething</code> in the configuration.</p> <p>If you want magical <code>GetObjectsOfType(...)</code> code, you can use the features of your DI container to create a <code>IMySomethingDoerProvider</code>.</p> <p>When using Spring, the second approach would require to create:</p> <pre><code>MySomethingDoerSpringProvider: IMySomethingDoerProvider { IList&lt;ICustomInterfaceThatDoesSomething&gt; GetAll() { // use Spring.Context.Support.ContextRegistry.GetContext() // .GetObjectsOfType(typeof (ICustomInterfaceThatDoesSomething)); } } </code></pre> <p>Which you can place in a project that depends on <code>sharedLib</code>. Since your <code>webApp</code> already depends on Spring.Core, you could place <code>MyProvider</code> there to get you started quickly.</p> <p><em>Notes</em></p> <p>If <code>DoSomething</code> is called once per instance, you might consider specifying an initialization method instead.</p>

    1. COinteresting, however i find that this solution just transfers the dependency somewhere else instead of the sharedLib. Additionally, it introduces at least 2 classes and an interface which have hardcoded logic... which i find inelegant to say the least. I know that this is a valid pattern but i still don't like it

    3. CO1 - `MySomethingManager` is an example class - you probably don't have to introduce this class in your project, just place the `SomethinDoers` list on the class that currently has the `GetObjectsOfType(...)`

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.
