Question

several classes in my dll require a set of the data ( general configurations ) . these data are provided by the one who uses the dll through implementing an interface IConfigs . so data should be injected as a dependency . now I wonder how to do that .

Update :

sorry , if the question was not clear . the problem is should I have an instance of IConfigs in each class that needs it and using constructor injection ( that I don’t like this approach ) or there is a cleaner way to handle this situation ?

Answer 1

You can use injection dependency by property.

If you use MEF :

Service

[Export(typeof(IServiec))]
public class Service : IService
{
 ....

}

Client

public  class Client  
{
    [Import]
    public IService Service
    {

    }
}
