C#

<br />
using System;<br />
using Perpetual_Settings;<br />
namespace Brazen_Mail<br />
{<br />
	/// <summary><br />
	/// Summary description for Setting.<br />
	/// </summary><br />
	public class Setting<br />
	{<br />
		public static Perpetual_Settings.PerpetualSettings test = new PerpetualSettings();<br />
		static Setting()<br />
		{<br />
			test = new PerpetualSettings();<br />
		}<br />
	}<br />
}<br />

But when running the code I get this error.

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll

Additional information: File or assembly name Perpetual Settings, or one of its dependencies, was not found.
