BitmapImage.BeginInit()

A very common error new UI developers make is trying to create new BitmapImages without properly initializing them.

All property changes made to a BitmapImage must be made between the BeginInit() and EndInit() calls. Every property change made after the EndInit() call is ignored.

Here is a small code snippet on how to properly create a new bitmap image and set that as the source of an Image object.

// Define a BitmapImage.
Image myImage = new Image();
BitmapImage bi = new BitmapImage();

// Begin initialization.
bi.BeginInit();

// Set BitmapImage properties. (CacheOption,CreateOptions… etc.)

// End initialization.
bi.EndInit();

myImage.Source = bi;
