“The property is read only” Error Using RIA Services

If you’re trying to modify the property of an object automagically generated from RIA Services within a Silverlight application and you’re getting a runtime error indicating that the the property is read only, here’s a simple fix. Simply add the attribute “[Editable(true)]” from System.ComponentModel.DataAnnotations at the top of the field that you’d like to be editable.

Is it just me or are the number of attributes needed to be placed before each property getting a little ridiculous?
