Регистрация своего VirtualPathProvider из Feature activation

Для регистрации своего VirtualPathProvider из Feature activation на понадобиться собственно какая нибудь фича, желательно со scope="WebApplication"
Выглядит это так:

using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
namespace QpmWcfSupport
{
    public class FeatureActivation : SPFeatureReceiver
    {
        #region Private Members
        SPWebApplication _chosenWebApp = null;
        #endregion
        #region Implementation Of SPFeatureReceiver
        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            Init(properties);
            WcfSupport(true);
        }
        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            Init(properties);
            WcfSupport(false);
        }
        public override void FeatureInstalled(SPFeatureReceiverProperties properties)
        {
        }
        public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
        {
        }
        #endregion

            mod.Type = modEntry.ModType;
            mod.Value = modEntry.Value;
            return mod;
        }
        private ModifcationEntry GetWCFSupportEntry()
        {

            wcfEntry.Name = "add[@name='WCFSupport']";

            wcfEntry.Value = "";
