TargetedPatchingOptOut: “Performance critical to inline across NGen image boundaries”?

It tells NGen that it is OK to inline the method it’s applied to even in a different assembly. For example: String.Equals has [TargetedPatchingOptOut] You write a program that calls String.Equals You run NGen on this program for maximum performance NGen will inline the String.Equals call, replacing the method call instruction with the actual code … Read more
