i can't comment yet (under 50 reputation) add conversation looks you're referencing 4.0.0.0 , 5.1.0.0 of system.web.mvc, not sure that's causing problem make sure you've got binding redirects or change version numbers version have referenced. i've had multiple problems stemming various mvc/webpages dll versions.

<dependentassembly>   <assemblyidentity name="system.web.webpages" publickeytoken="31bf3856ad364e35" />   <bindingredirect oldversion="1.0.0.0-3.0.0.0" newversion="3.0.0.0" /> </dependentassembly> <dependentassembly>   <assemblyidentity name="system.web.mvc" publickeytoken="31bf3856ad364e35" />   <bindingredirect oldversion="1.0.0.0-5.1.0.0" newversion="5.1.0.0" /> </dependentassembly>
