Silverlight - temporary *.XCP files created

Very recently, I had run across a problem with Silverlight where temporary files (*.XCP) were being created in the temp folder when a user was using IE7 (or IE6). These continued to be created without getting cleared up. They were not cleared up even when the browser was closed. Only a manual delete removed these files. Some explanations and solutions are given here[^]. Unfortunately for me, even adding GC.Collect() to the code did not fix this problem. After further analysis, I was able to trace the problem down to this KB[^]. Installing IE Security update 969897[^], however, finally fixed this issue for me. A link to this hotfix is also provided within the KB. I thought I'd collate this information and post it in a tip to help anyone else who might encounter a similar problem. Cheers
