SYMPTOMS

In some Microsoft Windows Presentation Foundation applications, you may lose system resources during the life of the application. Additionally, you may see a decrease in the performance of the computer.

If you examine the Private Bytes value of the application process in Performance Monitor when this problem occurs, the value keeps growing and never decreases.

CAUSE

Applications that do not immediately display visual resources may slowly run out of system resources when the visual resources are continually displayed during the life of the application.

MORE INFORMATION

When a DeferredResourceReference reference is used by a ResourceReferenceExpression class, the internal Inflated event causes a strong reference to be held to the expression. This keeps the whole visual tree from being collected by the Garbage Collector after the references are removed from the tree if the DeferredResourceReference reference is never inflated.
