    <p>I'm developing an addin for a commercial application to expose very simple informations about document opened in that application and so on. The applications itself don't support COM or NET addin but only C++ addin in a DLL.</p> <p>I want to expose some informations to COM clients and some informations NET clients running in the same machine.</p> <p>For COM clients I developed in C# an implementation of a COM interface; then I create an object when the host application start and I register the object in the Running Object Table. Deriving this implementation from <code>StandardOleMarshalObject</code> appear sufficient to solve threading issue: apparently the methods of my implementation are called only on main UI thread at message boundary, which is a requirement.</p> <p>And for NET clients? I need different informations and I don't need to rely on a specific COM interface to expose these information. I was tempted to develop and host a WCF service, but my service methods are called on non-UI therad and the host application crash. How can I replicate the <code>StandardOleMarshalObject</code> behavior in a WCF context? I need to implement an <code>IOperationInvoker</code>? Any suggestion to do <strong>this</strong>?</p> <p>Thanks to all and please excuse my bad english.</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.
