Why am I getting this WCF Error Message?

Question

I am getting the error below when I call my WCF service. What am I missing here?

\'System.String[]\' with data contract name
\'ArrayOfstring:http://schemas.         


        

Answer 1

In my case, after adding [Serializable] attribute to the MyEntity class. And then the issue came with serialization of the roles string array.

    [Serializable]
    [KnownType(typeof(string[]))]
    public class MyEntity
    {
       .........
       public string roles[]
       ......... 
    }

[KnownType(typeof(string[]))] worked like magic!
