Hi everybody,

I have a working solution consisting of 3 projects. One of them is Windows Form which is used for testing. I just added some code to that form.

I didn't touch the main program (program.cs) and yet all of the sudden it gives an error on this code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms; // Error here

namespace MiddlewareTest

Error 1 The type or namespace name 'Windows' does not exist in the namespace 'System' (are you missing an assembly reference?) C:\_Siriusware\Main\Siriusware.Middleware\Siriusware.Middleware\Program.cs 4 14 Siriusware.Middleware

----------------------
In the references I do see System.Windows.Forms

Why would I get this strange error?

I'm going to try closing VS 2013 and re-opening.
