Today I was setting up a new project that was using Castle Windsor’s NLog integration facility. However, when I tried running my ASP.NET MVC project I got the following error:
Could not load file or assembly ‘NLog, Version=2.0.0.0, Culture=neutral, PublicKeyToken=5120e14c03d0593c’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
The solution was to add the following entry in the configuration file
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="NLog" publicKeyToken="5120e14c03d0593c" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-2.0.1.0" newVersion="2.0.1.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
It is important to note the xml namespace. This workaround, I believe, is not specific to NLog or Castle. From my limited understanding, this is caused by the fact that I’ve got a newer version of NLog (2.0.1.0) while Castle Windsor is expecting version 2.0.0.0.
