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.

I watched a video on WCF with this exact error and it was never explained. http://channel9.msdn.com/shows/Endpoint/Endpoint-Screencasts-Self-hosting-WCF-Services/

You need to have administrator privilages to host the WCF service.

To do this, right click on your project, add new item. Select application manifest file.

This will generate you a basic manifest file.

You need it to contain <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

The overall file (cut down) will look like this

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

You can bind this manifest to the compiled .exe file if you need to, or just leave it in the same directory as the compiled project output (the .exe file) You can tell if it works because VS2010 will ask to restart with administration priv's when you try to debug.
