NUnit test case
DataContractJsonSerializer throws an exception when deserializing a subclass of List<T>.
Related to bug 3811, but the attached NUnit test case works in Microsoft .NET Framework 4.5 even without specifying known types as 3811 does.
I'm using Ubuntu 13.10 with Mono 22.214.171.124-5ubuntu2.
