Closed Issue: Nested class is not supported by QueryableAttribute [346]

To repro:

public class Parent
{
public class Nest
{
public string Name { get; set; }
}
]

Put Nest as action return type:
[QueryableAttribute]
public IEnumerable<Nest> Get()

Throw following exception:

System.InvalidOperationException occurred
