I'm writing a custom WCF binding that would like to control using configuration. To be clear, I'm not talking about using the standard <customBinding> element, but rather inheriting from Binding and writing a full class.

My binding isn't very complicated, and I really only have one property that I would like to set through config, useSsl. However, I am having difficulty getting .NET to recognize my configuration attribute even though I believe I have everything in order.

Binding

public class MyCustomBinding : Binding {

    public MyCustomBinding() {
        // Initialization
    }

    private bool _useSsl;

    public bool UseSsl {
        get { return _useSsl; }
        set { _useSsl = value; }
    }

    // Remaining implementation omitted

}

Binding Configuration Element

public class MyCustomBindingElement : StandardBindingElement {

      protected override Type BindingElementType {
          return typeof(MyCustomBinding);
      }

      // public const string UseSsl = "useSsl"
      [ConfigurationProperty(ConfigurationStrings.UseSsl, DefaultValue: true)]
      public bool UseSsl {
          get { return (bool)this[ConfigurationStrings.UseSsl]; }
          set { this[ConfigurationStrings.UseSsl] = value; }
      }


      // Remaining implementation omitted

}

Binding Configuration Collection Element

public class MyCustomBindingCollectionElement
    : StandardBindingCollectionElement<MyCustomBinding, MyCustomBindingElement> {}

I've registered the collection element in my web.config file:

  <extensions>
      <bindingExtensions>
          <add name="myCustomBinding" type="MyCustomWcf.MyCustomBindingCollectionElement, MyCustomWcf"/>
      </bindingExtensions>
  </extensions>

Then in my <bindings> section I add an instance of my custom binding.

<myCustomBinding>
    <binding useSsl="false" />
</myCustomBinding>

However, I receive the following configuration exception at runtime:

Unrecognized attribute 'useSsl'. Note that attribute names are case-sensitive

If I do not specify any properties on my binding, then it works. What am I doing wrong here?

At a quick glance. You specify ConfigurationStrings.UseSsl, but in the config you put useSsl. Can you correct this and try again?

The "Properties" property of MyCustomBindingElement also need to be updated as below. Hope helpful ...

    protected override ConfigurationPropertyCollection Properties
    {
        get
        {
            var result = base.Properties;
            result.Add(new ConfigurationProperty("useSsl", typeof(bool)));

            return base.Properties;
        }
    }
