Trying to create a web service with a method that returns 'System.Collections.SortedList'. It could accept it as a parameter, too. So, the function
[code]
<WebMethod()> Public Function ColTest() As SortedList
ColTest = New SortedList()
ColTest.Add("X", "Test X")
ColTest.Add("Y", "Test Y")


End Function

[\code]

returns the error "The type System.Collections.SortedList is not supported because it implements IDictionary."
after it's built and run.
Any Ideas?
