    Update umbraco from 7.2.8 to 7.3.0 with Nuget

    I try update umbraco from 7.2.8 to 7.3.0 with Nuget in my project. When the upgrade process is complete I try to run my project, but get an error:

    Could not load file or assembly 'System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    Edit:

    I try changed my web.config:

      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.1" newVersion="4.0.0.1" />
      </dependentAssembly>
    

    to

      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
      </dependentAssembly>
    

    Then I running my site and got on a page update umbraco. After update, I tried to enter my username, but received a new error enter image description here

    And running my site through iis became very slow. Up to 2 minutes per page load.

    Hi Shada,

    Did you use VS2015 for the upgrade? If you didn't, it needs to be to get the MVC5 support.

    HTH

    Now I'm using VS2012 with support MVC5. I also tried to update through VS2015 and got there the same error.

    You could install VS2015 Community Edition for free then update ;(

    I'm already on VS2015.

    I found the solution for me. I think the issue was that another reference in my solution was dependent on MVC 5. I updated all packages I had installed from Nuget and the error went away.
