HTTP could not register URL (remote debugging) - wcf

Question

C#, Windows 7.
I write an AutoCAD plugin and use the remote debuging (MS Visual Studio). My plugin must work as a WCF service. AutoCAD is unmanaged application and must to be as a host for my service. I am reading a book about WCF, and I try use it. I can't use acad.exe.config for my service settings: I have not permission. So I do it myself (I will read them from my xml file, but later, after refactoring). Code of my "server" (this code start by AutoCAD):
private static void RunServices() {
Ap.Document doc = cad.DocumentManager.MdiActiveDocument;
try {
Uri address = new Uri("http://localhost:8000/CadService");
BasicHttpBinding binding = new BasicHttpBinding();
binding.Name = "httpBinding";
binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
binding.Security.Mode = BasicHttpSecurityMode.None;
host = new ServiceHost(typeof(CadService));
host.AddServiceEndpoint(typeof(ICadService), binding, address);
host.Open(); // I get an Exception here...
if (doc != null) {
doc.Editor.WriteMessage("Service launched.\n");
}
}
catch (Exception ex) {
if (doc != null) {
doc.Editor.WriteMessage("Exception: {0}\n", ex.Message);
}
}
}
I get an exception (look the code comment):
Exception: HTTP could not register URL http://+:8000/CadServices/.
Your process does not have access rights to this namespace
(see http://go.microsoft.com/fwlink/?LinkId=70353 for details).
But the http://go.microsoft.com/fwlink/?LinkId=70353 page is not exist. I try launch MS Visual Studio 2013 as admin (I read about this here), but It is not help me (look P.S.2 bellow).
P.S. If I launch AutoCAD as admin - all works fine.
P.S.2 If I launch the remote debugger as admin - all works fine too.
But I need use it as a usual user. Can I start my service (hosted in the AutoCAD) without the admin rights?

Answer 1

This is probably because AutoCad does not have the required rights to register the port in HTTP.SYS. In that case you have two options:
Start Autocad in Admin mode
Register the port / endpoint in HTTP.SYS manually. For this, there are several tools available. This is the one I would use : http://www.codeproject.com/Articles/437733/Demystify-http-sys-with-HttpSysManager
Let me know if this works
