This section guides you through installing the CodeRush extension. Follow the steps below to add the CodeRush extension to Visual Studio 2017 (the process is similar for all supported Visual Studio versions).
The CodeRush extension is available on the Visual Studio Marketplace and can be installed directly from the Visual Studio IDE. Open the Tools | Extensions and Updates... menu item. Use it to open the Extensions and Updates window.
Select the Online tab at the left part of the Extensions and Updates window.
Use the search box at the top to find the CodeRush extension. Select it and click Download.
Wait until the downloading process is finished.
The VSIX Installer window should pop up once the Visual Studio IDE is closed. Read the License using the link on the right and click Modify to start the installation if you accept all its terms.
Once the installation is finished, close VSIX Installer and open Visual Studio. The registration window should pop up. Choose the required option and follow the on-screen instructions to activate your trial or paid license.
Refer to the GUI Install Mode article for detailed information on the registration window and the offline registration process.
