asp.net - Why global.asax Application_Error method does not catch exceptions thrown by ASMX service?

Question

And how to fix it. I'd like to log every thrown exception for maintenance purpose.

Answer 1

This is a known issue in .Net - Application_Error never fires for a web service. Not sure if there's any reason it would be by design, but it just doesn't work.

Jeff Atwood had a post (and follow-up) about this a few years ago, with the following ideas:

• Put a try-catch block around each web service method
• Use a facade design pattern and include the try-catch in parent objects
• Write a custom SOAP extension or HTTPModule

The only one I care for is the first one, even though it seems like a lot of work.
