Orient db .NET Client- Crearing Database pool issue

OClient.CreateDatabasePool("127.0.0.1", 2480, "GreatfulDeadConcerts", ODatabaseType.Graph, "root", "hello", 10, "myTestDatabaseAlias");

Gives an exception:

An exception of type 'System.IndexOutOfRangeException' occurred in App_Web_5r0zgx2y.dll but was not handled in user code

Index was outside the bounds of the array.
