LoadObjectV2 notsupportedexception

Question

I created an usercontrol with a property of type SetOfImageFilenames:

[Serializable]
public class SetOfImageFilenames
{

    private string name;
    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private string image_filename;
    public string ImageFilename
    {
        get { return image_filename; }
        set { image_filename = value; }
    }

    private string image_disabled_filename;
    public string ImgageDisabledFilename
    {
        get { return image_disabled_filename; }
        set { image_disabled_filename = value; }
    }

    private string image_pressed_filename;
    public string ImagePressedFilename
    {
        get { return image_pressed_filename; }
        set { image_pressed_filename = value; }
    }

    public SetOfImageFilenames()
    {
        this.name = "";
        this.image_filename = "";
        this.image_disabled_filename = "";
        this.image_pressed_filename = "";
    }

    public SetOfImageFilenames(string image_filename, string 
    image_disabled_filename, string image_pressed_filename)
        : this()
    {
        this.image_filename = image_filename;
        this.image_disabled_filename = image_disabled_filename;
        this.image_pressed_filename = image_pressed_filename;
    }

    public SetOfImageFilenames(string image_filename, string 
    image_disabled_filename)
        : this(image_filename, image_disabled_filename, "")
    {
    }

    public SetOfImageFilenames(string image_filename)
        : this(image_filename, "", "")
    {
    }


}

When I add the control to the toolbox and put into the form off-line, all is right, but I have a runtime error:

NotSupportedException on method ResourceReader.LoadObjectV2

it seems like you deployed on your device the System.dll for compact framework version 1 that does not contain the definition for LoadObjectV2.
Check the version of the System.dll you are using in your project references: in case change it to 3.5

the system.dll version is ok, is 3.5. The problem raises when when I run the application, there are problems with the generic collections (List) when are properties of a Custom Control – Sere May 16 '17 at 15:10
