Visual Studio 2019 Invalid Command Line. Unknown Switch : deferUpdateConfiguration. RRS feed

  • Question

  • I just tried to update visual studio.  It crashes and says "Invalid Command Line. Unknown Switch : deferUpdateConfiguration."

    It then asks me to restore the last project I happened to have opened before did the update.

    Now its asking me to reboot the computer.

    Is this normal for visual studio update?

  • Hi nutmix,

    Welcome to MSDN forum.

    No, it seems that there is something that interfered with the update process.  Please try to follow these tips ,and close anti-virus software or other third process when updating.

    Any feedback will be expected.

    Best Regards,
