Cannot debug wcf calls from wpf app

Question

I have many WPF/WCF applications and all are setup the same using the same frameworks, security, authentication, exception handling, etc.  I'm able to debug WCF calls on the server in all apps except for one even though it seems to be configured exactly like all others which debug as expected.  In all cases I'm using IIS from Windows 10 Pro and VS 2017, and call the web services like this:

http://localhost/someApp.Web/SomeService.svc

the solutions is configured for debug, Any CPU.

Web.config:  <compilation debug="true" targetFramework="4.7">

Any ideas on what else i can look for to understand why this solution wont step into calls on the server but similar solutions will?

Thank you.

Answer 1

Is it running the breakpoints? 

Did you try Attaching the Debugger to the WPW3.exe that is servicing the Application Pool that is hosting the Web application? 

Answer 2

Hi moondaddy,

For accessing http://localhost/someApp.Web/SomeService.svc, what do you want to Debug, WCF method or any other code?

Could you share us the complete steps you try to debug from launch WCF Service and call WCF from WPF?

Best Regards,

Tao Zhou
