Use .http files in Visual Studio 2022

The Visual Studio 2022 .http file editor provides a convenient way to test ASP.NET Core projects, especially API apps. The editor provides a UI that:

• Creates and updates .http files.
• Sends HTTP requests specified in .http files.
• Displays the responses.

This article contains documentation for:

• The .http file syntax.
• How to use the .http file editor.
• How to create requests in .http files by using the Visual Studio 2022 Endpoints Explorer.

The .http file format and editor was inspired by the Visual Studio Code REST Client extension. The Visual Studio 2022 .http editor recognizes .rest as an alternative file extension for the same file format.
