Step 1: Creating a Project and Adding a UDF Reference

Last modified: December 02, 2009

Applies to: SharePoint Server 2010

In this step, you will create a project and add a reference to Microsoft.Office.Excel.Server.Udf.dll.

The following project uses Microsoft Visual Studio 2005.

Note Note

Depending on which settings you use in the Visual Studio integrated development environment (IDE), the process to create a project could be slightly different.

To create a project

  1. Start Visual Studio.

  2. On the File menu, point to New, and then click Project. The New Project dialog box appears.

  3. In the Project Type pane, select Visual C# Projects.

  4. In the Templates pane, click Class Library.

  5. In the Name box, type SampleUdf.

  6. In the Location box, type the path where you want to save your project, or click Browse to navigate to the folder.

  7. Click OK. Your new project appears in Solution Explorer. You also will see that a file with the default name of Class1.cs has been added to your project.

  8. You should see the following code in the Class1.cs file:

    using System;
    using System.Collections.Generic;
    using System.Text;
    namespace SampleUdf
        public class Class1

The following steps show how to locate Microsoft.Office.Excel.Server.Udf.dll and how to add a reference to it.

To add a reference

  1. On the Project menu, click Add Reference.

  2. In the Add Reference dialog box, on the .NET tab, select Excel Services UDF Framework.

    Note Note

    You can also open the Add Reference dialog box in Solution Explorer by right-clicking References and selecting Add Reference.

  3. Click OK.

    Note Note

    The previous steps assume that you are building the project on a computer that has Microsoft SharePoint Server 2010 installed. On the computer where you have installed SharePoint Server 2010, you can find a copy of Microsoft.Office.Excel.Server.Udf.dll at:

    [drive:]\Program Files\Common Files\Microsoft Shared\web server extensions\14\ISAPI
