PRB: Web Services XmlInclude Does Not Work on Enumerations (326792)

SYMPTOMS

You have an enumeration in your Web service, but it is not used as a parameter or return type for any of the Web methods. You want the enumeration definition to be included in the Web Services Description Language (WSDL) document for the Web service, so you try to use XmlInclude, as follows:

public class MyWebService : WebService
{	
	public enum MyEnum
	{
		Item1,
		Item2,
		Item3
	}

	[XmlInclude(typeof(MyEnum))]
	[WebMethod]
	public string HelloWorld()
	{			
		return "Hello World";
	}
}
				

However, the generated WSDL document or the proxy does not include the enumeration definition.

	public class MyWebService : WebService
	{	
		public enum MyEnum
		{
			Item1,
			Item2,
			Item3
		}

		class MyEnumWrapper
		{
			public MyEnum dummy;
		}

		[XmlInclude(typeof(MyEnumWrapper))]
		[WebMethod]
		public object HelloWorld()
		{			
			return "Hello World";
		}
	}
