Windows Forms window changes its size when I create a WPF window

Question

I have a System.Window.Forms.Form where I handle every button click. When I receive the first event I create a new WPF System.Windows.Window object

These is some method you can use. Set the width and height of the window:

public static Graphics graphics = Graphics.FromHwnd(IntPtr.Zero);
public static double GetDIPIndependent(double value, double DPI)
{
    value = value * (graphics.DpiX / DPI);
    return value;
}
public static double GetDIPDependent(double value, double DPI)
{
    value = value * (DPI / graphics.DpiX);
    return value;
}
public static double GetDIPIndependent(double value)
{
    value = value * (graphics.DpiX / 96.0);
    return value;
}

public static double GetDIPDependent(double value)
{
    value = value * (96.0 / graphics.DpiX);
    return value;
}

Example:

If DPI independent

this.Width = GetDIPIndependent(this.Width)
this.Height = GetDIPIndependent(this.Height)

If DPI dependent

this.Width = GetDIPDependent(this.Width)
this.Height = GetDIPDependent(this.Height)

It works for me...
