Could not load file or assembly 'Microsoft.Practices.Unity'
I am trying to upgrade Unity to version (2.1.505.2), but when I run the application I get the following FileLoadException
Could not load file or assembly 'Microsoft.Practices.Unity, Version=2.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
We are upgrading from Unity 2.0.414.0 to 2.1.505.2.
- All project references in the solution that refer to Unity refer to the correct version of the dll
- There is no Unity dll referenced in the Gac. (double checked by checking
gacutil -l) I removed all Unity dlls from the archive. Double checked with powershell
PS C:\> ls -rec -inc Microsoft.Practices.Unity.dll | foreach-object { "{0}`t{1}" -f $_.FullName, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).FileVersion }
How can I find out what / who still refers to the Unity 2.0.414.0?
FusionLogVw doesn't tell me which DLL is causing the problem.
Any help is much appreciated!
Answer
The problem was another Microsoft dll that refers to the old version of unity. I found this out be accident be checking the namespaces of every referenced dll, and found another dll that contained namespaces with "unity".
Updating:
- Microsoft.Practices.EnterpriseLibrary.Common
- Microsoft.Practices.EnterpriseLibrary.Validation
to latest released versions resolved the problem.
I hope I save the day for some lost soul out there who's also pulling his hair out over this issue... :)
