Using System.Dynamic not recognized

Question

I am using Visual Studio 2010 .NET 4.X and I'm trying to use the ExpandoObject class, but I'm getting a not recognized error on the using System.Dynamic statement.

I made sure to add a reference to System.Core, but that didn't resolve the issue. Is there anything else I need to do?

Are you compiling for .NET 4.0 or higher? – Joachim Isaksson Apr 04 '16 at 20:10 — Joachim Isaksson, Apr 04 '16 at 20:10
"Are you missing an assembly reference?". Yes. – Hans Passant Apr 04 '16 at 20:12 — Hans Passant, Apr 04 '16 at 20:12

Make sure you have a reference to the assembly System.Core.

To do this, find your project in the solution explorer, right click "References", and click "Add Reference...". Then, in the assemblies list, find System.Core, and add it.

Where can I download the Dynamic reference ? – O.Deitch Apr 04 '16 at 20:29
@O.Deitch you don't need to download it. You just need to add a reference. I updated the answer to explain how. – vcsjones Apr 04 '16 at 20:31
THANKS Got It! I added the reference to the assembly but it still DOESN'T WORK... – O.Deitch Apr 04 '16 at 20:47

This moved to System.Dynamic at some point.
