> Project: TinkerPop
> Issue Type: Improvement

> As [described on the mailing
> list|https://lists.apache.org/thread.html/368c4aa3b37ef9628a3af612aece93fe9ca1914e3b3393e7e2e9fbdd@%3Cdev.tinkerpop.apache.org%3E],
> the limitation for of the specification combined with the strictness of .NET
> generics, makes dealing with maps on the .NET GLV hard / impossible.
> All methods returning a map have this issue, as in the following example:
> {code}
> IDictionary<string, IList<int>> result =
> g.V().ValueMap<IList<int>>("age").Next();
> {code}
> Causes an exception at runtime:
> {code}
> System.InvalidCastException: Unable to cast object of type
> 'System.Collections.Generic.Dictionary`2[System.Object,System.Object]' to
> type
> 'System.Collections.Generic.IDictionary`2[System.String,System.Collections.Generic.IList`2[System.Int32]]'.
> {code}
> We should provide conversion mechanism inside the default traversal.
