actualizar de MVC4 a MVC5 (4)

¿acabas de actualizar las referencias del proyecto? ¿También revisaste el web.config? También se hace referencia a esas bibliotecas y, por lo general, con números de versión específicos de la biblioteca.

en el archivo web.config puede encontrar las bibliotecas a las que se hace referencia, por ejemplo, en:

<runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> </dependentAssembly> </assemblyBinding> </runtime>

He cometido el espantoso error de actualizar de MVC4 a MVC5 prelanzamiento actualizando la máquina de afeitar y la página web de mvc en mis referencias Tengo System.Web.Mvc , System.Web.Webpages , System.Web.Webpages.Razor y System.Web.Razor como versión v4.0.30319, cuando ejecuto mi aplicación obtengo

¿Es esto lo mismo que http://www.asp.net/whitepapers/mvc4-release-notes

Gracias

Aquí está todo el Views/Web.config de un nuevo ASP.NET MVC 5 con motor de vista Razor 3. Out of the Box (OOTB), archivo original sin formato.

Es más o menos un conjunto y olvidarlo, así que espero que esto ayude con las actualizaciones de MVC4 a MVC5. Asegúrese de verificar / hacer una referencia cruzada de sus versiones de Referencias de proyectos. Pasé a utilizar NuGet solo para administración de paquetes y administración de dependencias.


Descubrió lo que debe hacerse en Views/Web.config . Simplemente copie y pegue estas secciones sobre lo que tiene:

<configSections> <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> </sectionGroup> </configSections> <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <pages validateRequest="false" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <controls> <add assembly="System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" /> </controls> </pages>

Y eso fue todo. ¡Trabajo hecho! :RE
