C4C: New Visual Studio 2022 Cloud Application Studio Plugin - Installation Notes

Submitted by Stefan Barsuhn on

The following is the process for installing SAP Cloud Application Studio via the "Visual Studio 2022 plugin" avenue:

  1. Install Visual Studio 2022 (Pro or Enterprise - Community Edition is explicitly not supported, you will get an error message if you try)
    1. No need to select any packages. Just the bare essential core is enough.
    2. You can also install the LTSC channel, so it doesn't bother you with frequent updates
  2. Download VSIX file from me.sap.com - follow guide at Updated SAP Cloud Applications Studio Installation Process – Effective August 2025 | SAP Help Portal
    1. Note that when installing a new release, you have to remove the extension (Extensions -> Manage Extensions ->  Extension Manager -> CopernicusIsolatedShell) first before installing the new one
    2. For the 2-week period when TEST operates on the old version and PROD on the new version, SAP advises in note 3639277 that you CAN install both extensions and enable/disable the required version to access the required system
    3. But good news is: You no longer need to migrate the system connections. They're preserved when removing the old/installing the new extension!
  3. Double-click VSIX file to install the plugin - with Visual Studio closed!
  4. When installed, open Visual Studio
  5. On Start Screen, select "Continue without code" - don't try to create a CopernicusIsolatedShell project, it will fail!
    1. Go to Tools => Options => Environment => General and select On Startup Open: Empty Environment to skip that start screen
  6. Select View => My Solutions to maintain system connections

Note: Starting with release 2508, the plugin is no longer compatible with Visual Studio 2022 LTSC, as this is based on 17.12 but 2508 requires at least 17.13. You'll get error  "The 'CopernicusPackage' package did not load properly". And ActivityLog.xml says: "Still unable to load MEF component DLL: Could not load file or assembly 'Microsoft.VisualStudio.Threading, Version=17.13.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"
