Hi,
I don't know if this is expected behaviour or a bug.
The following code does not compile with mcs but works fine with csc
=20
> using System.Xml.Serialization;
public class SerializableClass
{=20
[XmlAttribute( Type=3Dtypeof(MyEntry) )]
public Entry myEntry;
}
public class Entry{}
public class MyEntry : Entry{}
It fails with the error CS0182: An attribute argument must be a constant =
expression, typeof expression or array creation expression.
