| microsoft.public.dotnet.framework.remoting |
| Hi! Anybody tried to host a remote (wellknown) object in IIS using Windows Integrated Security? I have but have trouble retrieving the (domain) name/id of the user accessing my remote object. I have tried "Environment.User" which gives me the username "ASPNET", and "HttpContext.Current.User...." but "HttpContext.Current" is null. Do I have to implement an Interface or what?

| Hi all, How can I implement the serialization of a object graph where some of the objects are referenced by an interface rather than a strong type?

| SafeNativeMethods exception when serializing (2 replies) |

I have tried just returning an image directly from my method, since I thought the remoting infrastructure takes care of serialization for you when marshalling by value. I have also tried serialzing the image myself into a memo... |

| Must I decide to use Remoting or not when developing the client? (2 replies) |

One customer could choose to have the business objects installed in an Application Server, and another customer could choose to have everything installed locally. In either case, the client app creates th... |
