Access Restriction Public


IsolatedStorageFileStream does not override certain public members of its base FileStream class, including GetAccessControl, SetAccessControl, Lock, and Unlock. When these methods are called, the base FileStream implementation is executed and because of how IsolatedStorageFileStream was implemented, these method calls throw a NullReferenceException.

This occurs on down-level versions of the .NET framework as well.
