static classes in ASP.NET

I have a static class Utils that defines some extension methods (eg. on String).

How can I use this in my ASP.NET page?   I would like to be calling things like Label1.Text = helloWorld.ToFrobbedString()

I am a newbie at C#, VS, and ASP.NET, so I need instructions about how to make the utility class somehow available to my own customized page class.   How are methods in the Utils class accessed by my ASP.NET codebehind (instantiated) classes?  What are the namespace (Using?) and Visual Studio things I need to do to link?

Utils.cs
========================================================================
namespace Utils
{
  public static class Basics
  {
    public static string ToFrobbedString(this String str)
    {
      return str + "Frobbed";
    }
  }
}
 
 
WebForm11.aspx.cs
========================================================================
namespace Mine
{
  public partial class WebForm11 : System.Web.UI.Page
  {
    protected global::System.Web.UI.WebControls.Label Msg1;
 
    public void Button_Click(Object sender, EventArgs e)
    {
      Msg1.Text = Msg1.Text.ToFrobbedString();
    }
  }
}

if your static class is a part of the same namespace as your class of ASP.NET page you can call it directly by class name and method name. Otherwise you should either put its qualified name, which includes namespace or declare its namespace by "using" directive. No special actions in VS are necessary in this case

If that static class is created in another project - assembly, you should add reference to that project/assembly in the properties of your ASP.NET project

WebForm11.aspx.cs
========================================================================
namespace Mine
{
  public partial class WebForm11 : System.Web.UI.Page
  {
    protected global::System.Web.UI.WebControls.Label Msg1;
 
    public void Button_Click(Object sender, EventArgs e)
    {
      Msg1.Text = Utils.Basics.ToFrobbedString(Msg1.Text.);
    }
  }
}

or

WebForm11.aspx.cs
========================================================================
using Utils

namespace Mine
{
  public partial class WebForm11 : System.Web.UI.Page
  {
    protected global::System.Web.UI.WebControls.Label Msg1;
 
    public void Button_Click(Object sender, EventArgs e)
    {
      Msg1.Text = Basics.ToFrobbedString(Msg1.Text.);
    }
  }
}
