配置COM +服务器

Question

There is COM+ server already running. I can see this in services.

Now, I want to install/configure a new version of this component. So, I stop the service. Copy new com+ dll and exe file to the location. Start the service and I get following error.

Remoting configuration failed with the exception 'System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

I get the same error when I run it in Visual Studio from the console app that is set as service and consumes COM+ server.

Another point to note is that Console App failes on RemoteConfiguration.Configure statement. As a test, I made a separate console app to make a direct call to COM component using 'new' keyword , which works fine.

What am I missing here?

I think you need to import the component into COM Services using the options in Component Services in Control Panel. If you just copy the new objects over the old ones then the new component won't be registered.
