We&rsquo;re addressing this performance issue in the next CLR 2.0 update delivered with .NET Framework 3.5. We will ensure that future updates made to the CLR and\/or Framework 2.0 assemblies will aggressively compile all critical framework assemblies (including WPF ones). Please note however that this change will only be effective for updates shipped post .NET Framework 3.5.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Current .NET Framework patches may not NGEN some assemblies as was recently discovered for KB928365.
