I have two assemblies, A.dll and B.dll.
A.dll contains two methods. One method, UsesB, uses a type from B.dll
whereas the other, DoesNotUseB, does not.
To cache a native image of A.dll with both methods precompiled, I believe I
can do
ngen A.dll B.dll
I think I could also do
ngen B.dll
ngen A.dll
Will just
ngen A.dll
also produce a native image of A.dll with both methods precompiled, or will
it precompile only the method that does *not* use types from B.dll? (or will
it precompile neither?)
In other words, does
ngen A.dll
resolve B.dll and use the metadata in B.dll to work out the physical layout
of the types in B.dll so that it can generate native code for A.UsesB(), or
does it need B.dll to be in the native image cache already, or do I actually
have to supply both dlls to ngen at the same time, ie
ngen A.dll B.dll
TIA

"ngen A.dll" is not the same as "ngen A.dll B.dll". The latter will
pre-compile both assemblies.
"ngen A.dll" will load B automatically (through the normal assembly probing
logic), and compile both methods.
To prove it, run "ntsd ngen A.dll", you will see b.dll in the loaded module
list, assuming b.dll can be found by ngen.

The ngen image of A will use indirections (similar to IATs in the unmanaged
world) to access data from B.dll. (In the next version, these indirections
can be removed).
We will resolve the physical layout of types in B. So if B.dll changes, you
need to re-ngen A.dll as the old ngen image is/may be invalid and will not
be used anymore.

If you have a .NET based application installed and you'd like to increase

the application is installed?
The application in question is quite a complex one and I doubt this will be

Thereafter it is likely that the publishers of the application will want to

Of course now my window code starts far slower, but I don't want to blindly precompile assemblies because from what I know that might just as well slow things down as speed them up.

NGen generates native code when i install the windows application on the

I was hoping to use nGen to speed up the time taken for our web site to
start running. However, on the web we found this quote:
"NGen is not recommend for Asp.Net because the assemblies NGen produces
cannot be shared between App Domains"
I'm afraid I'm not sure what an App Domain is in this context, but we don't
have a web farm/web garden. It's a single web site running on IIS 6. We do
not use the GAC for any of our assemblies.

Hi guys
I've just read the article in this months MSDN about using Ngen to speed up
initial load times and I thought "great, I can speed up initial load of my
web app!".
However, having just read the conversation between Steven Cheng and MLibby
on this group (search for "ngen" to find it) - I'm thinking my plan is
scuppered. Then again, that's 2004.

Hi all,
I am looking into NGen.exe to solve a problem. At my firm, when we upload new code to the live servers they take an age to start up. I've heard that NGen can speed this time by be JITing the IL assemblies. However it seems that NGen is run on a per machine basis, so I would still have to run it after copying it across. is it possible to copy NGen'd assemblies between machines so you don't need to NGen again?
cheers
