Delphi Windows Service
The 'Introduction to WCF Programming in Delphi' session starts from WCF object model basics, including message-based communication stack, service contracts, endpoints, transports, exchange patterns, and interoperability with Web Services.
I have created a windows service in delphi. My code is run within ServiceExecute
Unfortunately, I can not get this code to run. I doesn't seem to call the procedure even when I'm debugging.The code in Myservice.exe looks like this.
I can get the serviceExecute to run if I add
into MyService.exe however if I install it as a service it appears not to be running as Application.Run does nothing
Not sure what I'm doing wrong, but any help would be much appreciated.
Thanks

Delphi Windows Service Install Fails
You cannot just run the service from the IDE to debug it; in that case it will just exit. The service has to be started by the service control manager. Also, you shouldn't be calling ServiceExecute directly.
Here's documentation how to debug services.
If you've created a service, you can install it by running it with parameter /install
After that, the service should show up between your other services (go to start/run/ and enter services.msc).
You can then start it, and you can debug it by attaching the debugger to it.
However, it's painful to work like that. I can't believe that some people actually work like that. I usually have all my business logic in separate units that I can run from a 'normal' application. Only when that works out good, I wrap it in a service and try that.
Sometimes I even create an application that can run both as a service or with a GUI. You can simply instantiate your service class. You just need to start it yourself, but it'll be a lot easier to debug.
There is commercial solution that was developed specifically to simplify service debugging process. You can debug your code directly from the Delphi IDE, including service's OnStart event.

Delphi 8 is a .NET-only release that compiles Delphi Object Pascal code into .NET CIL. The IDE has been rewritten for this purpose and has changed to a docked interface similar to Microsoft's Visual Studio.NET.
