Visual Studio - windows form app(.NET Framework) crashes when I hit start button RRS feed

  • Question

  • Hi,

    So I have been working with windows form App(.NET Framework) for a few days, and it worked just fine.

    lately whenever I try to start the application it crashes and I get the message "WindowsForm has stopped working".

    I tried to uninstall visual studio and than install it again but that didn't work, also tried to repair visual studio - didn't help..

    I don't know why it happens, I tried to run windows form on my laptop and it worked, in addition other templates work.

  • Hi OfriAlum,

    Please check if you installed the same .NET Framework as your laptop. You can create a new Windows Form project and check if the situation occurs in specific project. You can also try the following methods:

    #1. Repair your .NET Framework;

    #2. Update your Visual Studio to the latest version;

    #3. Enter “devenv /ResetSettings” at Developer Command Prompt to restore your Visual Studio default settings;

    #4. Remove the .vs folder in the project folder and re-run your project.

    Since this forum is related to .NET Framework Setup and Servicing, if it persists, I recommend you report it in Microsoft Q&A tag Windows-Forms for a better help. Thank you for your understanding.

    Hope it helps.
