Overtime C# source code files may have unnecessary & unorganized using directives. Visual Studio IDE organize using options can help you to unclutter the source code.

To organize the C# code right click anywhere inside the code editor, select Organize usings.

• Select Remove Unused Usings to remove any using directives that are not used in the source code (this may remove some required using directives if the source code doesn't build)
• Select Sort Usings to organize alphabetically the using directives (by default directives that begin with System comes before other using directives)
• Select remove and Sort to perform both of the above operations
