upgrading from MVC4 to MVC5 pre-Release
- by Jack M
I have made that dreadful error of upgrading from MVC4 to MVC5 pre-release by updating the razor, and mvc webpage in my references I have System.Web.Mvc, System.Web.Webpages, System.Web.Webpages.Razor and System.Web.Razor as version v4.0.30319, when I run my application I get
[A]System.Web.WebPages.Razor.Configuration.HostSection cannot be cast to
[B]System.Web.WebPages.Razor.Configuration.HostSection.
Type A originates from
'System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location
'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.WebPages.Razor\v4.0_2.0.0.0__31bf3856ad364e35\System.Web.WebPages.Razor.dll'.
Type B originates from
'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location
'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\membership\c70f06fe\9163b1ca\assembly\dl3\291c956e\73c25daa_cf74ce01\System.Web.WebPages.Razor.dll'.
is this the same as http://www.asp.net/whitepapers/mvc4-release-notes
Thanks
Adding a stacktrace:
