问题 How do I choose between standard tracing, Logger.NET, Enterprise Library, log4net or Ukadc.Diagnostics? Is there a situation where one is more appropriate than the other? ... what would that be? (ASP.NET, console app, Azure Cloud, SOHO, Enterprise...) What are the benefits or drawbacks? Did I miss any other major logging frameworks? 回答1: There are many similar questions here on SO: Logging best practices log4net versus TraceSource Silverlight Logging framework and/or best practices log4net vs

问题 We're moving a solution with 20+ projects from .net 2.0 to 3.5 and at the same time moving from Visual Studio 2005 to 2008. We're also at the same time switching from MS Entlib 2.0 to 4.0.

Edit: I might been a bit confused when I wrote this, the backwards compatability is supposed to mean; is there anything that

问题 So I'm trying to use Enterprise Library in my WCF service to do some of the exception-related work for me. My idea is to set up a " Custom Exception Handler " for say "NullReferenceException" and in the "Custom Exception Handler" create FaultException exception. My understanding is that this "new" exception will then make it across the wire and I will catch it at the client. Some code for better understanding: WCF service: [ServiceContract(Name="MyService", ConfigurationName="MyNamespace
