    Steps to reproduce

    1. Open visual studio 15.9.5
    2. File → New Project
    3. Windows Forms App (.NET Framework)
    4. Project name: DeleteC1EditorTest
    5. .NET Framework 4.6.1
    6. OK
    7. Toolbox → C1 WinForms 4.0 → C1Editor
    8. Add that to the created Form1.vb
    9. Press delete after adding it

    Expected result: The created C1Editor is removed from Form1

    Actual result: A Microsoft Visual Studio dialog pops up: “An Error occured while processing this command. Object reference not set to an instance of an object”
