I need to attach to aspnet_wp.exe in order to debug a web serivice from
WinForm client. Why don't I have to do this for ASP.NET / WebForm client?

Why doesn't VS.NET debugger attaches automatically? Can I configure it?

Thanks,

-Stan

Hi Stan,

It should be configured. Use F11 to step into web service method call and
see it there is any difference.

I cannot even set a breakpoint inside of the web service - it is
unreachable..
Debugger does not step into the web service untill I attach it manually

Sometimes I'll add the System.Diagnotics namespace and manually throw a
Debugger.Launch() just to force the issue...

I wish there were a better solution. Debugging a web service from WinForm
client is very unproductive. Not only do I need manually attach to
aspnet_wp.exe process but even doing so takes a long time. You set a
breakpoint, hit F5 and sit for a minute watching how VS.NET loads modules
in Output window.

It just takes too much time...

Martin,

It actually makes a difference - once I stop before the web service call and
then click F11, the debugger goes into the web service.

If I just set the breakpoint inside the web service and hit F5 - it does not
stop there.

This behaviour is different from debugging regular dlls or library serviced
components - debugger stops everywhere..

Thanks for the tip!

Hi Stan,

I had this issue some time ago and I was very puzzled with it. In the early
days of VS2002 this used to work without having to stop and then hit F11
AFAIK.

Glad that this helped you.

Actually, I just realized that I don't even need to debug this any or any
other web services because initially I built the service wrong - web service
class that sits in code behind should not have any logic. The logic should
be in a separate component that should be called from a web service. In this
setup I almost never need to debug a web service, because it is not doing
much - just a pass through code. Instead I need to debug the component that
is being called.
