I found several topics related to this problem, but none of them solved my problem.
I previously used log4net version 1.2.10.0 in my ASP.NET services. I updated it to the current version of log4net v2.0.8.0 , due to some third-party libraries I also added the following lines to web.config to support / redirect older versions.
<runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="log4net" publicKeyToken="1b44e1d426115821" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-1.2.10.0" newVersion="2.0.8.0" /> </dependentAssembly> </assemblyBinding> </runtime>
I am also confused in these posts by an Internal Exception: ((System.IO.FileLoadException) ex.InnerException.InnerException) .Message
Could not load file or assembly 'log4net, Version = 1.2.10.0 , Culture = neutral, PublicKeyToken = 1b44e1d426115821' or one of its dependencies. The installed assembly manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

perhaps the following lines indicating a problem in FusionLog

Update
after a suggestion by Ciprian Lipan in the comments, I found this entry in .csproj in which the PublicKeyToken was different from my web.config . I copied this token and replaced it in config and received only the message with the exception, the internal exception disappeared. below is an entry in .csproj
<Reference Include="log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a, processorArchitecture=MSIL"> <HintPath>packages\log4net.2.0.8\lib\net45-full\log4net.dll</HintPath> <Private>True</Private> </Reference>
Exception
Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=**1b44e1d426115821**' or one of its dependencies. The located assembly manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
however, I wrote the token in config with the new one found in .csproj
