Yet another issue about log4net 1.2.11 conflicts
c#, gac, log4net
Solution
Here was my solution: I changed from log4net to Common.Logging to NLog. It didn't take a lot of effort, and I don't think it should have been necessary, but it worked, and worked well.
Problem
I've spent the last 2 hours looking over these issues on SO, and nothing seems to be working. I have a solution that uses log4net 1.2.11, via NuGet. It works fine on my 32 bit development workstation running Windows 7. It does not run on my 64-bit Windows 2008 R2 test system. The error I get is: Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'log4net, Version=1.2.11.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. I am looking in the application directory on my test system. The `log4net.dll` file there is version 1.2.11. The version in the GAC was version 1.2.10. I have removed it. There was a version on my development server that was yet again something else; I removed that as well. I have rebuilt; I have redeployed. I have added ``` <dependentAssembly> <assemblyIdentity name="log4net" publicKeyToken="669E0DDF0BB1AA2A" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-1.2.10.0" newVersion="1.2.11.0"/> </dependentAssembly> ``` to my configuration file. Nothing seems to make a bit of difference. My deployment project shows the right version and signature of the log4net assembly that is being deployed. I do not know what else I can do, but I am getting quite frustrated that a logging library is preventing my application from running. What have I missed?
