#1,213 – Visual Studio 2015 – Unused using Statements Greyed Out

In Visual Studio 2015, the editor will grey out any using statements that are not required.  This is done at build time.  Note that you can still use the Remove Unused Usings command to remove any unused statements.  (This command has been renamed Remove Unnecessary Usings).

Below, all but the first using statement is greyed out, since the code that follows makes no use of types from any of the other namespaces.
