oh and also gac does not imply ngen. An assembly can be gac'd but have no native image (or it could be invalid) in which case jit still occurs. Of course ngen without gac usually is worse than jit so maybe you should only ngen gac assemblies and always re-ngen them since ngen is smart enough to know if an image is up to date.

I'd type my version but I'm on my stupid iPhone.

I'm getting a ton of errors indicating assemblies that can not be found... this isn't expected is it?

Below is the content of the Update-GAC.ps1 script that I run whenever I install a new version of PowerShell.

Similar to Chris' comment earlier... we accidently ran this script while in Exchange Management Shell rather than just in PowerShell. We saw errors similar to this:

WRN: Assembly binding logging is turned OFF.

To enable assembly bind failure logging, set the registry value [HKLM\So

ftware

\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind fa

ilure

logging.

To turn this feature off, remove the registry value [HKLM\Software\Micro

soft\F

usion!EnableLog].

You state this is fixed in V2, but when I installed V2 CTP3, it had the same slow start bug, until I ran this script. This really needs to be fixed.

I ran both versions of this script under the EMS and regular powershell. It didn't resolve the EMS start-up problem or the EMC start-up problem. It is taking over a minute to load each one. In fact the EMC often times out when "expanding". It's a real handicap, and additional advice would be appreciated.

On my machine I ran this and the script got an error - due to-- after the sort, the first item going into the Split-Path --was null.

add the following

if ($_.location){

##only if there is a location code executes

## within the foreach(%) after the sort

}
