Polymorphic web services (asmx)

Filed under: Uncategorized — andreakn @ 12:43

I had the “pleasure” of creating a dummy web service having only the required interface to work with. and discovered that the service had a method which took polymorphic data.

After spending a bit of time poking at it with a stick I realized that the magic trick was to tag the service methods with XmlInclude attributes for each of the child types that could be sent over.

Also I realized that I’m not a huge fan of polymorphic web service methods.
