如何从项目类访问ASP默认属性？

Question

I have a class that tries to access the options of the web app, but fails to compile during Run or Debug.

CS0122: 'IBBFCP.Properties.Settings' no es accesible debido un su Nivel de Protección (It is not accessible due to its protection level)

The code is very simple and will only publish important parts:

public class HelperFideicomiso : IDisposable
{
    private String Url
    {
        get
        {
           return global::IBBFCP.Properties.Settings.Default.WSLA_FideicomisoEndpointURL;
        }
    }
}

The project compile but fail running.

The property is well constructed by the Visual Studio 2005 IDE and value stored in Web.config

The class is internal to the project, there is no reference or DLL involved.

Thanks.

Simplifying the stage. After creating a web application, define a property and reference it from a page and a class get the same error:

CodeBehind:

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.Label1.Text = WebApplication1.Properties.Settings.Default.Setting;
        this.Label2.Text = new Configuracion().Setting;
    }
}

Referenced class. This class fail :

internal class Configuracion
{
    public string Setting = WebApplication1.Properties.Settings.Default.Setting;
}

In your project, expand Properties and double click on the Settings.settings file. This will open it. Look at the top in the toolbar, and change the Access Modifier to Public.
