Commented Unassigned: cant use closedXML [9484]

hi, i cant use ClosedXml.

I'm using Visual Studio 2015 4.6 .NET framework
i only created a new Windows Forms Application project with visual studio 2015.
i added reference ClosedXML.dll.
i added only a button with this following code:

using ClosedXML.Excel;

namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
var workbook = new XLWorkbook();
}
}
}


the exception is:

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in System.Windows.Forms.dll

Additional information: Could not load file or assembly 'DocumentFormat.OpenXml, Version=2.5.5631.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

how can i fix the error?

thanks!!!.





Comments: CLosedXML depends on OpenXML, therefore you need this reference as well. The easiest would be to use the ClosedXML Nuget Package.
