How to compare the 64bit systems GAC using powershell?
Parameters: Assembly name full name version
+2
A:
Not sure exactly what you're after but if it is to compare 32-bit and 64-bit GAC'd assemblies try something like this:
PS> $gac64 = gci C:\Windows\assembly\GAC_64 -r *.dll |
select @{n='AQN';e={"$($_), $((Split-Path $_.PSParentPath -leaf) -split '__' -join ', ')"}} |
Sort AQN
PS> $gac32 = gci C:\Windows\assembly\GAC_32 -r *.dll |
select @{n='AQN';e={"$($_), $((Split-Path $_.PSParentPath -leaf) -split '__' -join ', ')"}} |
Sort AQN
PS> diff $gac32 $gac64 -Property AQN
AQN SideIndicator
--- -------------
Mcx2Dvcs.dll, 6.1.0.0, 31bf3856ad364e35 =>
Microsoft.MediaCenter.Interop.dll, 6.1.0.0, 31bf3856ad36... =>
Microsoft.MediaCenter.iTV.Media.dll, 6.1.0.0, 31bf3856ad... =>
Microsoft.MediaCenter.Mheg.dll, 6.1.0.0, 31bf3856ad364e35 =>
Microsoft.MediaCenter.Playback.dll, 6.1.0.0, 31bf3856ad3... =>
Microsoft.MediaCenter.TV.Tuners.Interop.dll, 6.1.0.0, 31... =>
Microsoft-Windows-HomeGroupDiagnostic.NetListMgr.Interop... =>
SoapSudsCode.dll, 2.0.0.0, b03f5f7f11d50a3a =>
Expression.DevHost.dll, 3.0.0.4000, 31bf3856ad364e35 <=
Expression.DevHost.resources.dll, 3.0.0.4000_en_31bf3856... <=
Microsoft.Expression.Encoder.Api2.dll, 3.0.0.0, 31bf3856... <=
Microsoft.Expression.Encoder.dll, 3.0.0.0, 31bf3856ad364e35 <=
Note that the splitting isn't foolproof (pretty naive impl) but it should be sufficient to compare what's different between 32-bit and 64-bit GAC.

Thanks for your help.Can you please elaborate the command line?$gac64 = gci C:\Windows\assembly\GAC_64 -r *.dll | select @{n='AQN';e={"$($_), $((Split-Path $_.PSParentPath -leaf) -split '__' -join ', ')"}} | Sort AQN so that i can customize as per my requirement.

gci path -r *.dll gets all the dlls located at path recursively. The select (select-object) cmdlet, can project the incoming object (a Syste.IO.FileInfo) to another object (PSCustomObject) by taking various properties from FileInfo, manipulating those properties in a single property called AQN. Select-Object accepts a hashtable to define this project where the Name entry ('n' for short) defines the property name and the Expression entry ('e' for short) defines the value of the property.
