      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?

      1. What would you like to communicate to the user about this feature? 2. Would you like the user to see examples of the syntax and/or executable code and its output? 3. Which versions of the driver/connector does this apply to?

      Example:

      class A { public int X { get; set; } }
      class B { public A[] A { get; set; } public int Y { get; set; } }
      class C { public B[] B { get; set; } }

       

      Support specifying "B.A.X" path by:

      var field = new ExpressionFieldDefinition<C>((C c) => c.B.Select(b => b.A.Select(a => 
      a.X))); 

      Note, the following expression is supported:

      coll.AsQueryable().Select(c => new {Xs = c.B.Select(b => b.A.Select(a => a.X))});
