    1. COThe "System.ComponentModel.Composition" (which is part of Managed Extensibility Framework(MEF)), and Unity both provide an implementation of the dependency injection pattern. But I'm not sure that it's a good idea to involve monsters to solve tiny problems. Just trying to find the right technique to make the third-party developer aware of what I will look for, and not only the EntryPoint and so, but also some meta-data. But thanks.

    2. COIf you want to import a lot of interfaces, dependency injection frameworks lets you roll tbh. I used import/export attributes for some .net4. But if you are targeting something less than v4 than you are right to be curious about referencing another lib. I tend to make my business objecs in a way that they always are initialized with a service provider. If there is anything they need they look-up for the service they need and they go on. In those terms you just need to have a service with Register method which is only registering plug-in's service back to the provider.

    3. COI've implemented a simple dependency injection which is enough for current case. Also I'm trying to make the code as simple as possible and self-explanatory, therefore, I tend not to use frameworks just to use them, if the program doesn't utilize most of the possibilities of the framework. Besides I want to figure out, how specification of meta data could be enforced on implementators. Just trying to learn...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
