Question

I’m looking for a way to unit test all the DTOs I’m sending back over my WCF interfaces. I want to avoid run-time errors like the following:

System.Runtime.Serialization.InvalidDataContractException 
No set method for property 'Bar' in type 'Foo'.

For example in the following I would want the unit test to catch the above exception.

[DataContract]
public class Foo
{
    [DataMember]
    public decimal Bar { get { return 0; } }
}

There is a useful helper in this SO article that’ll help you to test serialization deserialization using the NetDataContractSerlializer. You could call this helper from your unit tests.

Has anyone created a DataContract testing tool?
