Hi All,

I've updated umbraco from 7.3.7 to 7.6.5 version using nuget and got some errors. The same as it's in the following topic https://our.umbraco.org/forum/using-umbraco-and-getting-started/85835-unrecognized-element-enablepropertyvalueconverters-after-upgrade-to-761 , but i have correctly pointed references, so it does not help (but I'm not sure)

The last error where i got stuck is:

Could not load types from assembly businesslogic, Version=1.0.6428.37125, Culture=neutral, PublicKeyToken=null, errors: Exception: System.TypeLoadException: Method 'ConfigureMappings' in type 'umbraco.BusinessLogic.ApplicationRegistrar' from assembly 'businesslogic, Version=1.0.6428.37125, Culture=neutral, PublicKeyToken=null' does not have an implementation. Exception: System.TypeLoadException: Method 'ConfigureMappings' in type 'umbraco.BusinessLogic.ApplicationTreeRegistrar' from assembly 'businesslogic, Version=1.0.6428.37125, Culture=neutral, PublicKeyToken=null' does not have an implementation.

My guess that this issue related to Automapper, but not sure.

I've added the following assembly bindings in web.config:

  <dependentAssembly>
    <assemblyIdentity name="AutoMapper" publicKeyToken="be96cd2c38ef1005" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.3.1.0" newVersion="3.3.1.0" />
  </dependentAssembly>
   <dependentAssembly>
    <assemblyIdentity name="AutoMapper" culture="neutral"/>
    <codeBase version="3.0.0.0" href="bin\automapper\AutoMapper.dll" />
  </dependentAssembly>

Before that i was getting an error with log4net reference and the following section helped me to avoid an issue:

  <dependentAssembly>
    <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.0.8.0" newVersion="2.0.8.0" />
  </dependentAssembly>
    <assemblyIdentity name="log4net" publicKeyToken="null" culture="neutral" />
    <codeBase version="1.2.11.0" href="bin\log4net-1.2.11-nokey\log4net.dll" />
  </dependentAssembly>

Now the weird thing: when i restart Visual Studio(2015) and run project without debugging(ctrl+F5) it works! After rebuilding or just building i got an error above. The same situation is after every restart of VS.

Any ideas?
