I'm trying to add a controller with read/write actions and views, using Entity Framework.
But when I try so, VS2012 tells me that "MVC scaffolding does not support Entity Framework 6 or later". I've read http://support.microsoft.com/kb/2816241 and tried to uninstall EntityFramework 6 and install 5 in Nuget Manager Console:
PM> Uninstall-package EntityFramework -force Removing 'EntityFramework 6.0.2' from OnlinebookingAdministrator. Successfully removed 'EntityFramework 6.0.2' from OnlinebookingAdministrator. Uninstalling 'EntityFramework 6.0.2'. Successfully uninstalled 'EntityFramework 6.0.2'.
PM> Install-Package EntityFramework -version 5.0.0 'EntityFramework 5.0.0' already installed. Adding 'EntityFramework 5.0.0' to OnlinebookingAdministrator. Successfully added 'EntityFramework 5.0.0' to OnlinebookingAdministrator.
But the error keeps showing up when I try to add the controller. Is there a solution to this?
Thought this could use some expanding :) As mentioned above ASP.NET MVC 4 scaffolding does not support EF6 or higher. This means that an older EF, compatible with MVC 4 will have to be installed. To do this:
In the Package Manager Console, uninstall the current EF package by executing the following command:
UnInstall-Package EntityFramework -Version <version number>
<version number> is the version number of the EF currently installed.
*NOTE: to find out what EF version is installed, run the following command in the Package Manager Console:
To avoid potential metadata problems the providers entry in the Web.config file will need to be removed:
Delete the following lines:
<provider invariantName=System.Data.SqlClient type=System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer />
Now, in the Package Manager Console Execute the following command to install Entity Framework 5.0.0:
Install-Package EntityFramework -Version 5.0.0
After a bit more digging
ASP.NET MVC 4 scaffolding does not support Entity Framework 6 or higher. Support of scaffolding of Entity Framework 6 is targeted for the next release of ASP.NET MVC.
So looks like ill wait until MVC 5 is properly released
