ASP.NET pages work locally, why not on a website?

[Vedder]

I am building a simple website that does a little bit of database select/edit/delete etc and I am working in VS 2005. The way I have set up the project in the development environment is:

index.aspx (this is the presentation etc...)

index.aspx.cs (this is the code behind stuff and basically calls methods from a classfile)

Class1.cs (this is my class file)

What is troubling me is, inside the development environment it works fine, but when I upload the site to my webspace and try to access the .aspx page I get the error:

Compiler Error Message: CS0246: The type or namespace name 'Class1' could not be found (missing a using directive or an assembly reference?)

I have set up an older computer as a local webserver and when I upload the files and test it out on that it works. This has been really puzzling me so I have made a simple "Hello World" type page to see if any of you guys can spot any obvious mistakes?

Here is my class file

public class Class1
{
	public Class1()
	{
		//
		// TODO: Add constructor logic here
		//
	}

    public string Message()
    {
        string Confirmation = "Hello There!";
        return Confirmation;
    }
}

and here is my index.aspx.cs file which creates an instance of that class and assigns a label to the Message() method.

public partial class index : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        GetTest();

    }

    public void GetTest()
    {
        Class1 TheClass = new Class1();
        Test.Text = TheClass.Message();
    }
}

Finally I have the index.aspx which the user sees, this is just a label but I
thought I would add the top line to be sure I have not done anything wrong:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="index.aspx.cs" Inherits="index" %>

Does anyone see anything obvious which would mean it doesnt work on my webspace? I have doubled checked and the website is running .NET 2.0. As far as I can see if it works locally and on a intranet, why not on a webhost's server?

Thanks for the replies. I had to enable the project as a 2.0 application through my webhost.
