Error with: using System.Data;

Question

using System;
using System.Data;
using System.Data.SqlClient;
...

I get the following error:

The type or namespace name 'Data' does not exist in the namespace 'System' (are you missing an assembly reference?)

I'm using Visual Studio 2013 Express for Windows Desktop

Are you sure you add `System.Data.dll` as a reference to your project? — Soner Gönül, May 24 '14 at 14:09
Well, *are* you missing an assembly reference? Have you added the reference to your project? — Ant P, May 24 '14 at 14:09

You are missing assembly reference. You need to add assembly reference.

Go to soution explorer right click on references and select Add Reference.

then Select System.Data assemly reference. enter image description here

That's it.

Press ok.

In the Solution Explorer window of Visual Studio right click on your project, and click Add Reference. There you can add assembly reference which are sometimes needed to use certain namespaces (like System.Data).
