Could not load file or assembly 'Microsoft.Practices.Unity'
assembly-loading, c#
Solution
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... :)
Problem
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!
