namespace JobManager
{
    public partial class Contact : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

Answer 1

Well the error seems to tell you, that your class JobManager.Contact is not inherited from System.Web.UI.Page class or one of its descendants.

So does it?

If it does, then you're going to have to provide some of your code as well, namely your page class definition for instance. We'll start from there.

Answer 2

Hi, I suggest you delete and add your form again, if you didn't made modifications too much.

I think this problem is caused by partial class. Let me explain. You can see your class is defined as partial class.

public partial class Contact : System.Web.UI.Page

So there can be another part of Contract class and that part can be corrupted or derived from another class. You can check this.

Answer 3

• Check if you have a namespace conflict with another assembly.
• Also delete your bin directory and rebuild your project.
