8.1 Upgrade can not find System.Web.Mvc 4.0 error in MVC templates
Gang,
I upgraded my dev solution to 8.1 and everything runs and compiles as expected, however when I publish the upgraded project to my production IIS box I am now getting the following error on my Feather MVC templates.
Could not load file or assembly 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040This same behavior happens with the Bootstrap, SemanticUI, and Foundations templates as well. I even deleted the ResourcePackages to those templates and copied out the new Feather version ones as still same error. Web Form templates work as expected.
I checked web.config and System.Web.Mvc 5.0 is referenced and the dll is in the bin directory.
What am I missing?
Hello Garry,
Do you have any external MVC assemblies in your project?
Please aslo che if you have the following assemblyBinding redirect in your web.config file:
<dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" /></dependentAssembly>
