Question

I’m trying to find, using Powershell, the AssemblyFileVersion of a deployed Sharepoint solution.

So far I manage to find that info about the solution itself, but now I’m trying to find the same about it’s references.

Is there a way to get that data.

Here’s my code so far

$assembly = [System.Reflection.Assembly]::LoadWithPartialName("<AssemblyName>")
$fvi = [System.Diagnostics.FileVersionInfo]::GetVersionInfo($assembly.Location)
Write-Host "File Version Number " $fvi.ProductVersion

$references = $assembly.GetReferencedAssemblies();
foreach ($ref in $references)
{
    Write-Host $ref.Version
}

The $ref.Version returns the AssemblyVersion which is not the same.

I tryed the same approach ([System.Reflection.Assembly]::LoadWithPartialName) but it does not work. I’m gessing that the fact that this is a sharepoint solution as an impact on this.

I was looking for a solution and find ReflectionOnlyLoad method which might help you.

$processed = @{}
function writeAssemblyFileVersions {
  param($parentAssemblyPath)
  if ($processed[$parentAssemblyPath]) {
    return
  }
  $processed.$parentAssemblyPath = 1

  $ver = [System.Diagnostics.FileVersionInfo]::GetVersionInfo($parentAssemblyPath).ProductVersion
  $assembly = [reflection.assembly]::LoadFile($parentAssemblyPath)

  Write-Output (New-Object PsObject -Property @{Version = $ver; Assembly = $assembly})
  foreach($a in $assembly.GetReferencedAssemblies()) {
    $aForLocation = [Reflection.Assembly]::ReflectionOnlyLoad($a.FullName)
    writeAssemblyFileVersions $aForLocation.Location
  }
}

###### sample
$loc = [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms").Location
writeAssemblyFileVersions $loc |   
  Select Version, {$_.Assembly.ManifestModule.Name}

It recursively checks for all the dependencies. The $processed cache is there so that it ends finally 🙂
