Cannot open C# project properties in VS 2019? RRS feed

  • Question

  • I cannot reach the properties page of any C sharp project in Visual Studio 2019. Right click on the project in solution explorer, choose properties, and I get:

    An error occurred trying to load the project properties window.  Close the window and try again.
    Value cannot be null.
    Parameter name: val

    Did a full update, reboot, repair, reboot of VS 2019.

    These work fine with VS 2017, only VS 2019 has this problem. This occurs for every C# project I have tried. This has persisted for a long time here.

    Has anyone encountered this? Is there a solution?
