GitHub Copilot code completions provide autocomplete suggestions inline as you code. These suggestions are generated based on the content from your currently active file and any other open files in your editor. However, we have discovered that incorporating more relevant context significantly improves these suggestions.

We are excited to announce that in Visual Studio 2022 17.11, our team has made changes to ensure that additional relevant C# context, such as available types and methods, is now included in Copilot completions.

With the latest version of Visual Studio, Copilot now automatically considers semantically relevant files for additional context, even if these files are not open in your editor. This improvement helps reduce hallucinations while offering more relevant and accurate suggestions.
