Issues that this hotfix rollup resolves

Issue 1:

ASP.NET applications that access additional functionality by using the application configuration settings can experience a deadlock at startup.

Issue 2:

The .NET Framework 2.0 and 3.5 applications will throw a NullReferenceException exception when they use GetEnvironmentVariable if the registry key does not exist.

Issue 3:
