error on resolving type when using Unity IoC

Hi,

I am getting an error:
The type name or alias ICategoryService could not be resolved. Please check your configuration file and verify this type name.

When trying to run this code from a website default.aspx.cs file:

protected void Page_Load(object sender, EventArgs e)
{
     var catService = IoCWorker.Resolve<ICategoryrService>();
}

This is the web.config registration, and attached below are the classes involved.
Also I should mention that everything compiles great and I added references to the website for all the projects involved in this.
