Properties on proxied interfaces not found by reflection

[GoogleCodeExporter]

If I proxy an interface with properties, the properties are not found by 
reflection. If instead I proxy an abstract class with abstract properties 
everything is fine.

I attached a patch file, containing two tests that reproduce the problem.

Hi Stefan,

Although I couldn't find a way to directly make the interface properties 
visible in
the test, here is a simple workaround that you can use if you're working with
interface properties:

var proxyFactory = new ProxyFactory();
            var wrapper = new InvokeWrapper();
            var customer = proxyFactory.CreateProxy<ICustomer>(wrapper,
typeof(INotifyPropertyChanged));

            BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
            Type proxyType = customer.GetType();

var typeProperties = proxyType.GetProperties();

var allProperties = (from currentInterface in proxyType.GetInterfaces()
                          from property in currentInterface.GetProperties()
                          select property).ToList();

allProperties.AddRange(typeProperties);

// Do something with the interface properties here...

Hi Philip,

thanks for the suggested workaround!

The problem is, I'm not the one who consumes the proxies. It is WPF when I 
databind the objects ;-) WPF does not 
look into all interfaces, obviously.

I have found another sort of workaround: with Castle DynamicProxy it works. I 
don't know how they implement it of 
course.
