Why System.Drawing.PointF is not listed at Properties.Settings types designer?

Question

I'm not able to find the type System.Drawing.PointF at the browse option at the type of the Properties Settings.settings. Why it is not listed there?

How to reproduce: Go to yours Projects Properties folder and click at Settings.settigs. At the type, select Browse, navigate to System.Drawing \ System.Drawing. You can see that there will be no PointF listed.

It might be the fact PointF does not have a TypeConverterAttribute but Point does. The way the settings provider works it needs a way to convert a string in to a object so the DefaultSettingValueAttribute can set the default value.

A workaround I have used in the past is break apart the class and dynamically construct it. In your settings file create two float settings called MyPointFX and MyPointFY. then click "View Code" at the top of the settings page, in the new file add the following code

public PointF MyPointF
{
    get
    {
        return new PointF(MyPointFX, MyPointFY);
    }
    set 
    { 
        MyPointFX = value.X;
        MyPointFY = value.Y;
    }
}

You will then be able to access MyPointF and behind the scences it will read and write the settings to the two variables MyPointFX and MyPointFY.
