| microsoft.public.dotnet.framework.remoting |
| Hello, I'm trying to write a Win2k Service and access it through remoting with a TcpChannel but I can't find the System.Runtime.Remoting.Channels.Tcp namespace. I can go as far the the Channels namespace and then intellisense doesn't show anything after that. Also, I cannot find it in the object browser. Even the docs say that this namespace exists. What might I be doing wrong? Thanks for the help... |

| EnterpriseServices with TcpChannel (4 replies) |
| microsoft.public.dotnet.framework.remoting |
| I want to use EnterpriseServices for my BusinessObjects, but I don't want to use Http as channels for the remote communication. Instead I would like to use TcpChannels. There is no problem to use HttpChannels and IIS as the host, but as I said that is not what I want. I would prefer to somehow skip the IIS entirely. Does anyone know how to do this? Do I have to write my own host application? /Klas... |

(I want to use DataBiding in the UI). I have seen, and read, some examples ... |
