I made a Visual Basic application in Visual Studio 2022. I downloaded the 2019 version, opened the application in it, wanted to redo the form, but instead I got a DesignToolServer.exe error saying that I need to install .NET Core. After clicking "yes" I was redirected to the .NET Core 3.1 download page. I downloaded it, but the error did not disappear. Also, there is no version of .NET Core in the project settings. Tell me what should I do?

    Did not think you can download vs2019 anymore.

    however, you need/want/should/good idea to install the .net framework tools for using and designs for a .net framework "desktop" application.

    I don't think they are installed by default.

    So, from vs2019, use tools->get tools and features. The installer/setup page will launch. You can close the topmost page, and then you want to select these options:

    (I'm using 2022 for this, but 2019 should be the same).

    So, choose this:

    And then choose to add/install these things:

    scroll down a bit, make sure these are also selected:

    Once done, exit VS, and re-launch. You should now have the .net framework bits and parts.
