how to determine which version of enterprise library a dll came from?

I have an application using a dll from the 'Microsoft Enterprise Librar开发者_如何学运维y'. How do I find out which version of the 'Enterprise library' the dll came from? The dll is 'Microsoft.ApplicationBlocks.ExceptionManagement.dll' and it's 'Product' and 'File' version is 1.0.3055.29252.

Your assembly is part of Exception Management Application Block. This was the first release from 4/23/2002 and actually predates the name Enterprise Library.

I think this was released only as source code so your build version doesn't help much.
