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
