How can i see the assembly version of a .NET assembly in Windows Vista and newer (WIndows 7, 2008)?
No. Not from explorer. It is an intentional move by Microsoft (although I dislike it).
You can from powershell though:
[Reflection.AssemblyName]::GetAssemblyName('full-path-to\xxxx.dll').Version
Also if file version is not explicitly set it will default to assembly version.
Here is some info: http://all-things-pure.blogspot.com/2009/09/assembly-version-file-version-product.html
Take a look at https://github.com/ssidpat/powerext
I know this is way late but I found this question when trying to find the extension again so others may find it too...
