Description Adam 2014-02-26 19:43:59 UTC
Using the following code:

            var over = new XmlAttributeOverrides();

            over.Add(typeof(BasicHttpBinding), "ProxyAddress", new XmlAttributes() { XmlIgnore = true });

            // also tried with          
            // over.Add(typeof(HttpBindingBase), "ProxyAddress", new XmlAttributes() { XmlIgnore = true });

            XmlSerializer ser = new XmlSerializer(typeof(BasicHttpBinding), over);

Fails with Exception:

There was an error reflecting field 'ProxyAddress'. ---> System.InvalidOperationException: There was an error reflecting type 'System.Uri'. ---> System.InvalidOperationException: System.Uri cannot be serialized because it does not have a default public constructor

This prevents the deserialization of this type.

I suspect the serializer requires some special support as System.Uri does not have a default (public) constructor.

Note: I had a look to see if it was linker related - but the issue exists even when not linking (e.g. simulator).

This was fixed at some point, likely by including MS RS code into the latest releases.

To make the above snippet work you have to add

> var bhb = new BasicHttpBinding ();

or something similar so the linker will not remove the default .ctor from the type being used.
