I am trying to create my first Excel add in with c#. I have Visual Studio 2010. I created a new project using the new project/c#/Office/2010/Excel 2010 Addin. It creates an event handler for this.Startup and this.Shutdown but I get an error that there is no definition for Startup or Shutdown. There is also a warning that Microsoft.Tools.Common.v4.0.Utilities is missing. I looked through all the .NET references and cannot find it. Where can I get it or what other reference will work?

What I have tried:

I have searched for the .dll using Google and have not found it.

I wonder what strange words you gave to Google; the first hit I got was Assemblies in the Visual Studio Tools for Office Runtime[^].

I did find that page on my first search. My problem is that I don't find Microsoft.Tools.Office.V4.0.Utilities in my list of .NET references so I can't add it to my project. The Visual Studio automatic project builder tried to add it and couldn't find it. I followed the link to download Microsoft.NET Framework 4 and I get an error message saying that I already had a higher version installed. I did find Microsoft.Tools.Office.V9.0 and tried adding that reference. I still get the same error that there is no definition for .Startup or .Shutdown

You need to download the tools dlls, they are not part of the .NET framework.

I spent a half hour searching the link you posted above and cannot find the tools dlls download. Can you possibly provide a direct link to the download I need?

I spent less than a minute with Google to find https://www.microsoft.com/en-GB/download/details.aspx?id=48217.

C#

#region VSTO generated code

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InternalStartup()
{
    this.Startup += new System.EventHandler(ThisAddIn_Startup);
    this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
}

#endregion

This is the automatically generated code which is causing the error
