Remove Unused References

  • Статия

This refactoring applies to:

  • C#
  • Visual Basic

What: For SDK style projects only, lets you remove unused references.

When: You want to clean up project references and NuGet packages that have no usage.

Why: Removing project references that have no usage can help save space and reduce startup time of your application, because it takes time to load each module and avoids having the compiler load metadata that will never be used.

Note

You can use the .NET Upgrade Assistant right from Visual Studio to upgrade your app to the latest .NET versions.

    Select Tools > Options > Text Editor > C# > Advanced, and enable Show "Removed Unused References" command in Solution Explorer (experimental).
