    With WM_GETMINMAXINFO

    For example :

    //  
    IntPtr hWnd = IntPtr.Zero;    
    private SUBCLASSPROC SubClassDelegate;    
    			  
    // after this.InitializeComponent();  
    hWnd = WinRT.Interop.WindowNative.GetWindowHandle(this);    
        SubClassDelegate = new SUBCLASSPROC(WindowSubClass);  
        bool bReturn = SetWindowSubclass(hWnd, SubClassDelegate, 0, 0);  
    
    //  
        private int WindowSubClass(IntPtr hWnd, uint uMsg, IntPtr wParam, IntPtr lParam, IntPtr uIdSubclass, uint dwRefData)  
        {  
            switch (uMsg)  
            {  
                case WM_GETMINMAXINFO:  
                    {  
                        MINMAXINFO mmi = (MINMAXINFO)Marshal.PtrToStructure(lParam, typeof(MINMAXINFO));  
                        mmi.ptMinTrackSize.X = 300;  
                        mmi.ptMinTrackSize.Y = 300;  
                        Marshal.StructureToPtr(mmi, lParam, false);  
                        return 0;  
                    }  
                    break;  
            }  
            return DefSubclassProc(hWnd, uMsg, wParam, lParam);  
        }  
          
          
        public delegate int SUBCLASSPROC(IntPtr hWnd, uint uMsg, IntPtr wParam, IntPtr lParam, IntPtr uIdSubclass, uint dwRefData);  
    
        [DllImport("Comctl32.dll", SetLastError = true)]  
        public static extern bool SetWindowSubclass(IntPtr hWnd, SUBCLASSPROC pfnSubclass, uint uIdSubclass, uint dwRefData);  
    
        [DllImport("Comctl32.dll", SetLastError = true)]  
        public static extern int DefSubclassProc(IntPtr hWnd, uint uMsg, IntPtr wParam, IntPtr lParam);  
    
        public const int WM_GETMINMAXINFO = 0x0024;  
    
        public struct MINMAXINFO  
        {  
            public System.Drawing.Point ptReserved;  
            public System.Drawing.Point ptMaxSize;  
            public System.Drawing.Point ptMaxPosition;  
            public System.Drawing.Point ptMinTrackSize;  
            public System.Drawing.Point ptMaxTrackSize;  
        }
