WPF FuturesMultitouch / Windows 7

Multitouch is coming (Natural User Interface)

Surface experience is leveraged for Win7

WPF is ready for Windows 7Jump List integrationThumbnail customization

WPF FuturesXAML 4 / C# 4

Improvement of the languages will improve WPF too!

More dynamicBetter interoperability

WPF FuturesPixel shaders

Replacement for BitmapEffectsToo inefficient (no GPU acceleration)Will no-op in WPF 4

Exception: Blur and DropShadow

Highly efficient, parallel computingOptimized for GPU

Pixel Shaders (HLSL)float4 myColor = { 0.5f, 0.2f, 0.4f, 0.2f };float4 colorFilter = {0.0f, 0.0f, 1.0f, 1.0f};float4 result = myColor * colorFilter;

<This is FOUR TIMES as fast as doing these operations separately, since they’re done in parallel>

result == {0.0f, 0.0f, 0.4f, 0.2f}

{result.x, result.y, result.z, result.w} …equivalent to {result.r, result,g, result.b, result.a}

<Grid> <Grid.Effect> <MyEffect /> </Grid.Effect></Grid>

Grid g = new Grid();MyEffect me = new MyEffect();g.Effect = me;
