Oh.... and in fact I think I don't even have to use that function at all.
OK, that version produces no error messages, and reports a frame rate of 85 fps (my native hardware refresh rate) but displays only a black window! Absolutely no graphics displayed at all.

I am on familiar territory here (blank screens) it happened to me a lot during development and may be related to the shader input
Code:
float4 Mandelbrot_PixelShader(float2 texCoord : SV_Position) : COLOR
The shader attempts to take the screen co-ordinates and then iterates them in the complex plane. Now this works 'this end'.
but originally the shader tried to take the texture co-ordinates
Changing that (and the offset to -0.5 rather than the screen dimensions) might work.. :P Also changing the shader versions might help... but it may not compile.
