1) Could someone tell me what are the steps invloved when the CLR loads
private assemblies on application startup (The assemblies are added to a
VS2005 Windows project using the Add References dialog).? Is it JIT loaded or
is it all done at app start up?
2) I guess this is related to question 1 but is there any performance
degradation at app start up if the number of referenced assemblies on the
application is large (35 referenced assemblies in my case)?

Any inputs or pointers to docs will be appreciated.
Thanks.
Naveen

You can see how the assemblies are loaded by using fuslogvw
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cptools/html/cp
grfFusionLogViewerFuslogvwexe.asp
which will show you exactly when the referenced assemblies are loaded. I can
tell you now though that they are added when needed not all at application
startup.

Thanks, Greg, for your reply. I'll take a look at the link. Based on your
reply, what then would be the performance difference (or where) on start up
between 2 applications that have, say, 25 references and a 100 references
added at design time respectively?

It depends completely on how they are used.

You might want to download ILMerge from microsoft to see for yourself if a
merged executable is faster. It will merge all your assemblies into one. If
the JIT time dominates it won't make much difference.
