In order to use any component in your application, you should add a reference to it. Follow these steps (assuming you use Visual Studio .NET):

1. In Solution Explorer, expand the project node you want to add a reference to.
2. Right-click the References node for the project and select Add Reference from the shortcut menu.
3. In the Add Reference dialog box, select the .NET tab (selected by default).
4. If you have used MSI installer to install Aspose.Cells, you will see Aspose.Cells in the top pane. Select it and then click the Select button.
5. You will see Aspose.Cells in the top pane, select it and then click the Select button.

• If you have downloaded or unpacked the dll only, locate the Aspose.Cells.dll file using the Browse button.
• Now you have referenced Aspose.Cells and it should appear in the SelectedComponents pane of the dialog box. Click OK. The Aspose.Cells reference will appear under the References node of the project.
