Last night I was just going through a tutorial and at some point i had to use .NET Framework’s ConfigurationManager class. But, while i was typing it wasn’t on the suggested reserved word list. And even if when i was typing it according to lower and upper case format, it wasn’t exist. So I made a little search on this and solution was little hard to find. Then i decided to post solution here to spread it.
Anyway, in order to use ConfigurationManager class in our project, we should add reference to System.Configuration into the project, rather than simply adding it with using statement. We should click on Project option in the file menu of Visual Studio and click on “Add Reference” option. Then searching through the .NET Components for System.Configuration
