Visual Studio 2019 will allow you to Remove Unused References from projects

This happens several times when we end up adding a huge list of dll/binary references in our projects. Later, it becomes difficult to find out the unused references and remove them one by one. With the next version of Visual Studio 2019 release, Microsoft is now going to offer you an option to clean up those.

In the first preview build of Visual Studio 2019 version 16.10, Microsoft adds a Remove Unused References command. It can be invoked by right-clicking on the project name or the dependencies node in Solution Explorer and select the "Remove Unused References..." command from the menu.

Once you select the "Remove Unused References..." menu item, it will open a dialog where you can view all the references that can be safely removed. It will also provide you an option to preserve the ones that you want to keep.

Microsoft says that the feature is off by default. You need to enable it from Tools > Options > Text Editor > C# > Advanced tab.
