I\'m learning DI, and made my first project recently.
In this project I\'ve implement the repository pattern. I have the interfaces and the concrete implementations.
you can easily do it with normal C# reflection, you don't need any extra technology.
There are quite a few examples on the web, e.g. http://www.codeproject.com/KB/cs/c__plugin_architecture.aspx
In general in your main application, you need to load the assembly implementing the plugin, e.g.:
ass = Assembly.Load(name);
and then you need to create an instance of your plugin. If you know the name of the class it would look like this:
ObjType = ass.GetType(typename);
IPlugin plugin = (IPlugin)Activator.CreateInstance(ObjType);
and then you just use it.
