Debugging RESTful WCF Service

Question

I am attempting to debug a RESTful WCF service I've created using a web browser as my client. Initially things go well however after stopping the debug session and making some changes to my code when I restart it's as if the old code is still being run. My breakpoints are ignored and it's as if a process is not being stopped.

I am running the service within Visual Studio and here's the URL I am asking the browser to retrieve:

http://localhost:25000/IntegrationService.svc/DeskQueue/tophd

It's clear the proper method is being called but the breakpoint I have at the top of the method is being ignored. Is there some external process I need to stop?

Thanks for any help.

Have you tried Cleaning then Building? – JustLoren Oct 27 '09 at 17:05 — JustLoren, Oct 27 '09 at 17:05
What host are you using? IIS or WebDev? – Drew Marsh Oct 27 '09 at 18:01 — Drew Marsh, Oct 27 '09 at 18:01
I have not tried Cleaning first. I am using WebDev. – Fred Strauss Oct 28 '09 at 15:17 — Fred Strauss, Oct 28 '09 at 15:17

Maybe it would be more convenient to deploy your service on IIS (Project settings->Web->Use Local IIS Web server, Create virtual directory) and then debug the service from Visual Studio (Debug->Attach to process->w3wp.exe).

You need to kill Cassini (the WebDev Server) as it's holding on to your older built WCF Server code....it doesn't automatically reload the newer DLL.

There are a few options:

You can manually stop Cassini by looking in your Notification area for the "ASP.Net Development Server" icon (yellow with world inside) and selecting Stop (via the context menu or Dialog).
You could install the Visual Studio addin KillCassini, so you just have to press a key combo to kill the server when you wanted it killed http://visualstudiogallery.msdn.microsoft.com/1269c9a1-fcfe-4b47-91e7-22c7027f3c41
You could turn on Edit-and-Continue, so that it restarts a new Cassini the next time you Debug Automatically stop/restart ASP.NET Development Server on Build

If you have some really exotic debug/test/run cycle then you could leverage a drop-in compatible replacement for Cassini that comes with source code.
