Alternative to BitmapSource.Create in Windows Store application (UWP)

Question

I have an Application written mostly in a PCL. When consuming this in an WPF Application I have a platformspecific codeblock that looks like this:

BitmapSource bitmapSource = BitmapSource.Create(generic.Width, generic.Height, 300, 300, PixelFormats.Bgra32, null, generic.ByteArray, generic.Stride);
        bitmapSource.Freeze();
        return bitmapSource;

where 'generic' is the PCL's platformagnostic representation of an image.

Now I want to Write an UWP Application based on this PCL, but BitmapSource.Create does not seem to exist there. What are my alternatives?

Update: I should inform that the PCL is under my control, in other Words I can change the behaviour if my approach is wrong. What I need is some way to display an image, which is generated in the PCL, pixel by pixel, in both WPF and UWP.

WPF and Universal Windows apps use different Xaml libraries in different namespace (System.Windows vs Windows.UI.Xaml) and so cannot directly share controls.

To create a programmatically generated bitmap in a Universal app use the WriteableBitmap class rather than directly creating a BitmapSource. The WritableBitmap is a BitmapSource which provides access to its PixelBuffer for the app to manipulate the bitmap's pixels.

Thanks. I was already started to head down that road. Using WriteableBitmap and writing to its PixelBuffer rendered my images! – Julian Hanssen Sep 12 '15 at 14:21
