Question

I wan to configure the unity container using ONLY xml (no fluent API) and I have a complex task.
I have an interface which looks like this

public interface ISettingsDistributor {
    String TargetProperty;
}

And its implementation SettingsDistributor

public interface ISettingsConsumer { }
public class SettingsConsumer :ISettingsConsumer, OtherType {
    public SettingsConsumer(String theParameter) : base(theParameter) {

    }
}

This is a consumer of that setting. The following is the configuration section I’ve built so far. (typeAliases and other stuff is omitted)

   <containers>
        <container name="container">
            <types>
                <type type="ISettingsDistributor" mapTo="SettingsDistributor">
                    <lifetime type="singleton" />
                </type>
                <type type="ISettingsConsumer" mapTo="SettingsConsumer">
                    <lifetime type="perThread" />
                </type>                    
            </types>
        </container>
    </containers>

How can I say to unity in this xml file that when it tries to resolve the type ISettingsConsumer it should first resolve the ISettingsDistributor and inject its TargetProperty member as a value to the constructor?

Answer 1

Why don’t you just inject your ISettingsDistributor?It will be the source of your magic string anyway.So whats the problem with that?
