Could not load file or assembly Common.Logging

I wrote class library to support writing a log using NLog and log4net with Common.Logging. When I test with project I get error

Could not load file or assembly 'Common.Logging, Version=3.3.1.0, Culture=neutral, PublicKeyToken=af08829b84f0328e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

FlushLog:

I had a similar exception in my .Net program. I had up and downgraded some nuget packages, which gave me the error and a mild headache.

I changed this in my App.config 

        <dependentAssembly>
            <assemblyIdentity name="Common.Logging" publicKeyToken="af08829b84f0328e" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-3.4.0.0" newVersion="3.4.0.0" />
        </dependentAssembly>

To this

      <dependentAssembly>
            <assemblyIdentity name="Common.Logging" publicKeyToken="af08829b84f0328e" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-3.3.1.0" newVersion="3.3.1.0" />
        </dependentAssembly>

The version number had changed due to the nuget upgrade and didn't revert during the downgrade.
