C1Studio and Visual Studio 2019: deprecated API

    Just installed C1Studio ("ComponentOneControlPanel20191.1.24.exe") on a Visual Studio 2019 testing machine, and Visual Studio pointed me to C1 extensions that use a deprecated API, see screenshot.

    You probably already know about this one ;-)?

    Best regards

    A bit more information: Visual Studio shows this warning message on startup:

    We are happy to inform you that the issue is now resolved. Please use the latest installer available at our website [https://www.grapecity.com/download/componentone-studio].
    The warning messages would then disappear.
    *Please uninstall ComponentOne (note down the serial key and deactivate ComponentOne before uninstalling) before running the latest installer.

    Best wishes,
