With the official release of Silverlight 3 RTW I received some feedback that my plasma sample wasn’t working anymore.
The problem occurs in some small changes in the Writeable bitmap api.
The official MS change document talks about the new constructor and the lock methods.
3.19 WriteableBitmap changes
The PixelFormat parameter for the WriteableBitmap constructor has been removed. WriteableBitmap(int pixelWidth, int pixelHeight, PixelFormat format) is now WriteableBitmap(int pixelWidth, int pixelHeight).
The only supported PixelFormat is now Pbgra32.
Similarly, the PixelFormat and PixelFormats type has been removed.Lock() and Unlock() have been removed.
But that’s not the only thing.
From now on you have to use the pixels property to write or read pixels.
I updated my previous sample and code.
