    Consider app.config remapping of assembly warnings after upgrade

    Upgraded from 7.2.8 to 7.4.2 and now have several warnings after build. For example, the first is: Consider app.config remapping of assembly "System.Web.Razor, Culture=neutral, 1> PublicKeyToken=31bf3856ad364e35" from Version "2.0.0.0" [C:\Program Files (x 1> 86)\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies\System.Web.Razor.dll] 1> to Version "3.0.0.0" [C:\Users\roger_000\Documents\Visual Studio 2013\Projec 1> ts\UmbracoWebsites\packages\Microsoft.AspNet.Razor.3.2.3\lib\net45\System.Web 1> .Razor.dll] to solve conflict and get rid of warning.

    Could you please advise what I do next?

    Your help would be much appreciated.

    Thanking you in anticipation.

    Roger

    Sounds like your web.config wasn't updated with the binding redirects to MCV 5.

    There's some details here: https://umbraco.com/follow-us/blog-archive/2015/7/29/upgrading-your-umbraco-site-to-mvc5-and-webapi2/

    I would mostly just do a winmerge/beyondcompare of a fresh 7.4.2 web.config against your current web.config, some more details of that here: https://umbraco.com/follow-us/blog-archive/2016/2/29/how-to-diagnose-umbraco-upgrade-problems/
