ExceptionCondition
IsolatedStorageException

The isolated store has been removed.

-or-

The write attempt exceeds the quota for the IsolatedStorageFileStream object.

Isolated storage is disabled.

ArgumentException

offset and count describe an invalid range in buffer.

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

Another thread may have caused an unexpected change in the position of the operating system’s file handle.

NotSupportedException

The offset parameter gives the offset of the byte in the buffer at which to begin reading, and the count parameter gives the number of bytes that will be written to this IsolatedStorageFileStream object. If the write operation is successful, the current position of the IsolatedStorageFileStream object is advanced by the number of bytes written. If an exception occurs, the current position of the IsolatedStorageFileStream object is unchanged.
