Error:

URL could not record. Do not have permission to access this namespace for your action C#

My WCf code:

namespace WcfServiceLibrary.OnDomainModels
{
    [ServiceContract]
    public interface IData
    {
        [OperationContract]
        int GetData();
   }
}


   public class Message : IData
    {
  public int GetData()
        {
            using (entity MaintCtx = new entity ())
            {
                return MaintCtx.NonRoutineCard.Count();
            }
        }

You need to give proper access the user account in which the host is running under. Use netsh form the command prompt

You can run visual studio as admin but this does not always work. I had many issues with this on Windows 7.
