WCF: server-side error handling. best practice
I write WCF service and want to keep it's activity log: trace, warnings and error messages. The very straight-forward approach is to wrap all contract service code inside try/catch
sections and write error messages from catch
part rethrowing service contract error exceptions.
I suppose it would be nice if there would be one code-point to catch all uncaught exceptions instead of dozens try/catch
sections. I开发者_JAVA技巧t would be also useful to write contract method parameters from that point to provide detailed error information.
Is it possible with WCF?
What is the best practice in organizing error handling inside WCF services?
Thank you in advance!
Have a look at IErrorHandler interface
It allows an implementer to control the fault message returned to the caller and optionally perform custom error processing such as logging
You can implement your service behavior (see IServiceBehavior interface) and add your handler to ChannelDispatcher error handlers.
See WCF Exception Handling with IErrorHandler for more details.
This article explains very well the different practices and the best one. Long but will probably answer your question.

I'm not sure if this works in WCF but you may try the AppDomain.UnhandledException Event.
