System.Configuration

This post is to share how a compiler warning helped me in discovering a wonderful tool...

When we use ConfigrationSettings.AppSettings["connection"]

we get a compiler warning-

This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings

So after changing the code to use ConfigurationManager class, you need to add reference to System.Configuration dll to your project. But why do I need to do this, how did it work before? The new class is now in a seperate assembly, but same namespace. Interesting! So I decided to see how it is split across assemblies..

That is when I started using the reflector tool and I cannot describe how wonderful this tool is to understand FCL assemblies and code.

I spend 30-60 mins every day with this tool from that day onwards. Higly recommended to every .net programmer.
