File Scoped Namespace Declarations
Reduce 1 Level of Indentation from your .NET classes using the File Scoped Namespace Declarations.
How to enable it?
Soon after the namespace abc.xyx, type in ";". Visual Studio would automatically convert your class declarations to File Scoped, thus reducing code clutter.
How to make this the default?
Visual Studio -> Tools -> Options -> Text Editor -> Code Style -> General. Here, under Code Block Preferences, Set the Namespace Declarations to File Scoped. This will ensure that all the new classes you create, have file-scoped declarations by default.
