As explained in another question , Ngen is usually only allowed to inline methods across assemblies if the method has the TargetedPatchingOptOutAttribute set. But is this also true for hard bound assemblies by using the DependencyAttribute with LoadHint.Always ? edit: Maybe the answer to my initial question is no, otherwise it would make no sense that the TargetedPatchingOptOutAttribute is used in mscorlib since this assembly is always hard bound (it has the DefaultDependencyAttribute set). So I'd like to rephrase my question: Is the TargetedPatchingOptOutAttribute the only way to get a method

How do I determine if the Native images are being used without the Loader verifing the signature of the assembly at runtime, or even using the GAC'ed assembly? I have complex system that we're experimenting with NGen but currently we're running the exe from the folder where all the DLL's are located due to a lot of late binding dependencies, looking at Process Explorer, it looks like the Native images are being used, but how can I be sure I'm getting the full benefit and eliminating the Loader Verification step? Cheers, Graeme. Update: I'm getting lots of this sort of thing from the Assembly

Is it possible to use NGen with ClickOnce deployment? Ron Actually you can use NGEN and clickone, but you are going to need to run the NGEN after the clickonce installation has happened, since NGEN is part of the .NET installation (for 3.5 you should refer to the 2.0 installation). Here is an example, I think it is generic enough for you to use it without changing or doing very little changes to the code (except for the call to your form): static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { if (ApplicationDeployment

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 Image Generator - Version 2.0.50727.3053 Copyright (c) Microsoft Corporation.

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? 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 application start up. JIT is only done per-method; it doesn't JIT everything... Only the bits you need. Of

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. m_eric 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 for every launch. Alternatively, you can use pre-compilation to reduce startup overheads related
