There are duplicate items in completion or menus when using ReSharper for VS Code extension

Problem

There are duplicate entries in the completion list, in the quick fix menu or duplicate tooltips in case of using ReSharper for VS Code extension.

Cause

ReSharper for Visual Studio Code includes code completion, code inspections, and quick fixes that may overlap with Microsoft C# and C# Dev Kit extensions.

Resolution

To avoid confusion from overlapping features and to get the full ReSharper experience, we recommend disabling the Microsoft extensions while using ReSharper. However, running all extensions simultaneously is valid; there is no technical limitation preventing their concurrent use.
