using DenemePc; <-- dll file

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

    }
}

ERROR:

'DenemePc' The type or namespace name could be found (are you missing a using directive or assembly reference?)

Answer 1

I believe I have answered a similar question ASP.NET => Compiler Error Message: CS0246: The type or namespace name 'HtmlAgilityPack'

Please set the Copy Local property to True on the Referenced DLL of DenemePc

This will copy the dll to the output directory of your application
