Question

I am defining a Color from argb , ex

Color.FromArgb(255,255,0,0);

In visual studio 2012 , winRT application it says that this is tagged with [security critical] . Are there any reasons why? I tried searching, no results. And no idea why this relates to security.

Update:

Now I notice, not only does FromArgb(…); methods gives this [SECURITY CRITICAL] warning. any of these:

c.A = 255;
c.R = 255;
c.G = 0;
c.B = 0;

Also does.

System.Drawing is a wrapper around unmanaged GDI+ code. From my understanding, WinRT does not support GDI+:

Native rendering code will need to be done with Direct2D.
