...sort out your assembly versions [a quick & dirty]: HRESULT: 0x80131040

Problem

The frustrating error message:

Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary… blah blah blah or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

 

Solved

I did a quick and dirty solution in my case because the version value causing the issue was an outdated version which I could not locate. I updated the values:

·         version ‘X.XX.X.X’ with the value of the assembly in VS assembly properties

·         PublicKeyToken ‘ XXXXXXXXXXXXXXXXXX’ with the value I got from running the command

"%ProgramFiles%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T

 <assemblies>
<add assembly=Microsoft.Practices.EnterpriseLibrary.Common, Version=X.XX.X.X, Culture=neutral, PublicKeyToken=XXXXXXXXXXXXXXXX"/>
</assemblies>
 

NOTE: You can add the functionality to get assembly Public Key Token to Visual Studio using this guy’s instructions.
