Could there be an option to globally address all these where it loops through those lines and removes the unnecessary usings?

I don't think we'll add a specific command for this. In VS Code, we'll to have the ability to provide "Fix All in {scope}" like we have in Visual Studio:

Now, eventually we might just have a general "clean up" command, but that's definitely different than a specific command only for remove unnecessary usings.

A general clean up command would be good ala Resharper

@DustinCampbell Before I go ahead and raise a separate issue for this, can you confirm if unnecessary usings should be highlighted in some way? If not, is there a specific motivation as to why? Currently I'm having to select each using until I find one that isn't needed so I can use "Remove Unnecessary Usings" to clear them all

[DustinCampbell]

@steve-lillis-cko: Follow the discussion on #1429 for the details. We've added an option in the latest beta of C# for Visual Studio to make hidden diagnostics appear in the editor and Problems tab.

A command for a remove usings would be nice for cases like that:

In this case I'm opening file by file and removing each unused using.

It would be great to have unnecessary using's to be highlighted (or greyed out, as per VS for Mac) in VS Code.

[DustinCampbell]

@jools-adams: Agreed. I'm tracking microsoft/vscode#20219 to get API support for VS Code so we can do exactly that.

@DustinCampbell did a separate issue get created for including removal of unused usings in a general cleanup command? As it stands, I need to jump back to VS2017 to efficiently clean up usings.

Hey @DustinCampbell - that language feature is ready now. Is there an ETA on using it?

Would love to see this feature added to VSCode.
