I just went through our german VB.NET forums and there was something interesting that gives me some kind of headache. It is actually possible to edit the .NET Framework assemblies using ReflexIL o...

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 under...

I have used NGEN to create native images of several assemblies used by my application. However, those images are not loaded when running the application and I have no idea why. This is a typical l...

Our app, distributed via ClickOnce, takes 10.8 seconds on average to start up. After running ngen on the .exe (in the directory that ClickOnce installed it into), it starts up in 6.4 seconds on ave...

If I NGen an assembly, is it normal that ildasm still disassembles it? Ok. I wrote a HelloWorld class library and the ensuing dll is named NGenILDasmTest.dll. --> Targeted for the .Net fw 4. Fro...

I've been working on a WinForms application which has about 5 referenced assemblies - written by us, and about 8 referenced assemblies by third parties (we wont be hoping to update them in the futu...

Is it possible to use NGen with ClickOnce deployment?

I was wondering if there's any way to change the behavior of the .NET JIT compiler, by specifying a preference for more in-depth optimizations. Failing that, it would be nice if it could do some ki...
