• T-Jay Windows Services (!Web Services), ASP.NET and RPC

• MyNameIsKen Launching a COM server from a service on WinXP 64-bit

  I have a 32-bit application that gets launched by a service. It is basically an MFC out-proc server. On a 64-bit machine, I am seeing an issue where a client is unable to communicate with this COM server.

• CSharpCoder What is remoting?

  Hi all, I have a field of type string in a type that is serialized to XML.
