Issues that this hotfix rollup resolves
Issue 1ASP.NET applications that access additional functionality by using the application configuration settings can experience a deadlock at startup.
Issue 2The .NET Framework 3.5.1 applications that are running on single core computers can freeze in GC code.
Issue 3The w3wp.exe process crashes with an exception when System.Web.Util.ResourcePool.Finalize() is called.
Issue 4ASP.NET applications that access additional functionality by using the application configuration settings can experience a deadlock at startup.
Issue 5The .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 6DirectorySearcher.FindOne() may throw overflow exceptions when it runs as a 32-bit process that is linked with the LARGEADDRESSAWARE compiler flag and runs on a 64-bit operating system that is configured to use 3 gigabytes (GB) of memory. Applications hosted inside IIS may see this exception when w3wp.exe is compiled as a LARGEADDRESSAWARE application.
This fix makes sure that memory addresses larger than 2 GB are handled correctly.
Issue 7When an update is being installed, Fusion can access a state in which NGEN is called repeatedly. This causes entries in the following registry keys keep growing until the computer freezes:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727\NGenService\Roots
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion\NativeImagesIndex
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
