Debugging a WCF service issue

A common scenario is your web service failing, but no application errors occur (assuming that you are catching all exceptions and logging them, that is). This is what I usually try:

• Turn on ASP.NET tracing (this is particularly important if you are setting aspNetCompatibilityEnabled to "true")
• Turn on WCF logging (don't forget to turn it off!)
• Take a look at Windows Event Viewer
