How do I catch unhandled Exceptions in Webservice (2.0)
 

Hello Everybody!

How do I catch unhandled exceptions in a Webservice application - .Net
Framework 2.0?

In Windows I can subscribe to the AppDomain.CurrentDomain.UnhandledException
event. In ASP.Net applications Application_Error event handler can be used.

How do I get a similar functionality in a Webservice application?

I would like to be able log errors globally, *on the server side*, without
using try/catch blocks all over the code.

Thank you,

Tomasz

Hello Tomasz,

As for the ASP.NET webservice application, the exception handling mechanism
of it is quite different from ASP.NET web application. the
Application_Error event only works for web page application. For XML
Webservice, since all the unhandled exceptions in application are captured
and wrappered as a SoapException, also , this exception will be serialized
as a Soap <fault> element in SOAP message.

If you want to add a global handler to intercept all the exceptions occured
in ASP.NET webservice, you may consider creating a custom soapExtension to
do the work. Here is a good tech article detailedly discuss on this:

If you have anything uncleaer on this, please feel free to let me know.
