Known Issue: Debugging on remote Windows 10 Device with Visual Studio 2015 Update 3, followed by Visual Studio 2015 Update 2 (or earlier), fails with DEP2100 or similar RRS feed

  • Question

  • If you debug a Windows application on a device using Visual Studio 2015 Update 3 or later, and then you or another developer tries to debug an application on the same device using Visual Studio 2015 Update 2 or earlier, the application will fail to deploy.


    The error message may vary depending on the version of Visual Studio that fails to deploy, but you may see:

    DEP2100: Cannot copy the file [FILENAME] to the target machine [IP ADDRESS]

  • To fix this issue, you can do one of the following depending on the remote device target:

    For all devices:

    • Make sure everyone working with the device is using Visual Studio 2015 Update 3 or later


    For remote PCs:


    For other devices (phones, IoT, Xbox, and HoloLens)

    • You can set the following registry key entry to work around the issue (if you cannot update to Visual Studio 2015 Update 3)
      • [HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio\14.0\Deployment]: "SshForceRedeployment" value set to 0x00000001 (registry type is DWord)
      • Note: You will have to create this registry folder as it will not already exist
      • Once this is set, you can F5 the application to the target device
      • After you have deployed the application once from that version of Visual Studio, you can change the value of the key to 0x00000000 (to improve subsequent F5 speed)
