Where can I find location of generated file after doing Ngen?

问题 I did Ngen on a C# executable. It was succesful, but I cannot figure out where the generated file is in my PC. MSDN says it should be in native image cache, still not able to figure out where it is.. EDIT : I want to run objdump on it, hence I need the physical file EDIT2: my putput of running ngen is : C:\Documents and Settings\nmea\My Documents\Visual Studio 2008\Projects\Consol eApplication4\ConsoleApplication4\bin\Release>ngen install ConsoleApplication4.e xe Microsoft (R) CLR Native

JIT vs NGen - what is the difference?

问题 So when CLR runtime load a .NET assembly, it compiles it into machine native code. This process is called JITing. NGen is also the process of compiling .NET assembly into native code. I don't understand what is the difference between two? 回答1: The difference is when they occur. The JIT compilation occurs while your program is running. NGen is a typically done at installation time of your program and happens before your program is run. One of the goals of NGen is to remove the JIT penalty from

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

Been going through some framework classes using reflector and noticed a number of the methods and properties have the following attribute [TargetedPatchingOptOut("Performance critical to inline across NGen image boundaries")] I'm pretty sure I have also seen the above comment somewhere else and never followed it up. Could someone please tell me what this means in the C# and any other context? SLaks 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

Does it help to use NGEN?

Is it better to use NGEN an ASP.NET application when we know it is not going to change much? Or is the JIT good enough? The only reason I asked was because this article by Jeffrey Richter in 2002 says : And, of course, Microsoft is working quite hard at improving the CLR and its JIT compiler so that it runs faster, produces more optimized code, and uses memory more efficiently. These improvements will take time. For developers that can't wait, the .NET Framework redistributable includes a utility called NGen.exe. NGen will only help startup time - it doesn't make the code execute any faster

How and when does ngen.exe work?

问题 I want to know the benefit of pre-JIT compilation (ngen.exe). What is the role of the Native Image Generator (NGen) process and why is it required? Please provide an example. 回答1: For code execution on the .NET platform, the Common Intermediate Language (CIL) representation needs to be translated into machine code. If this happens immediately before execution this is referred to as JIT (Just In Time) compilation. Output of JIT is not persisted so your managed application has to go through JIT
