Is there a way to set up our MVC3 apps to use newer versions of Razor? I tried using NuGet, but apparently there must be some additional wiring that needs to be done because I don't see the new features such as URL Resolution and Conditional Attributes working.
Install ASP.NET MVC 4
Remove the reference to System.Web.WebPages 1.0 and System.Web.Helpers 1.0, then add a reference to System.Web.WebPages 2.0 and System.Web.Helpers 2.0
Inside root web.config file, add/update these settings:
<appSettings>
<add key="webpages:Version" value="2.0.0.0" />
<add key="webpages:Enabled" value="true" />
<add key="PreserveLoginUrl" value="true" />
...
<add assembly="System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
...
<dependentAssembly>
<assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
Inside Views web.config file, add/update these settings:
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
Was asking on the Asp.net forums and found out that the RazorEngine on NuGet is not quite the same thing as the built-in Razor View Engine.

Im doing a web application in C# and ASP.NET MVC4.
On inspection of the web.config file I noticed that MVC4 has this:
<system.web>
<compilation debug="true" targetFramework="4.0" />
whereas if you look in the MVC3 web.config file you will see the following:
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</assemblies>
</compilation>
So, my question is why are the assemblies not in MVC4 web.config? Or are they elsewhere?
Many thanks.
Most of this is now all "rolled up"
namespaces are what you typically will now see
If you need to add in an Assembly you are free to do so.
http://www.asp.net/whitepapers/mvc4-release-notes
You should still be able to do this:
<compilation debug="true" targetFramework="4.5">
<assemblies>
<add assembly="System.Data.Entity, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</assemblies>
</compilation>
if you scroll a bit you'll see the both web.config have the namespaces added in them, I guess that would do.
<pages>
<namespaces>
<add namespace="System.Web.Helpers" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="System.Web.WebPages" />
</namespaces>
</pages>
I was working on a site in mvc4 using visual studio express 2012. Due to reasons I won't bother getting into here, I have to move the project back to mvc3 vs 2010. I have all the code moved over and compiling but when I run the project I get the following error. I have no idea what to do here. Anyone have a guess? Thanks.

In my root web.config I have the following...
<appSettings>
<add key="webpages:Version" value="1.0.0.0" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
Then in the web.config in the views folder I have...
<appSettings>
<add key="webpages:Enabled" value="false" />
</appSettings>
Not seeing your web.config I'm not certain if this is correct. But this error message points to the webpages:config setting being incorrect. Therefore please try the following:
In your web.config change the following
<appSettings>
...
<add key="webpages:Version" value="2.0.0.0" />
....
</appSettings>
to
<appSettings>
....
<add key="webpages:Version" value="1.0.0.0" />
....
</appSettings>
UPDATE
Another possible cause of this error is the binding redirects that MVC4 adds by default, i.e.
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
Please remove the above from your web.config and replace it with
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>
Penfold, thanks for trying to help. Although neither of your solutions were the fix, they pointed me in the right direction. I had a couple of blocks in my view's web.config file that were leftover from the original mvc4 and needed updated to mvc3. I started a new mvc3 project and copied over the defaults and it worked. Here's what I changed.

For an ASP.NET MVC3 project, I decided to move from the standard SQL express membership provider to an SQL compact membership provider. I installed the microsoft universal provider nuget package (mentioned here: http://sqlcemembership.codeplex.com/).
This gave me the following error:
Unable to find the requested .Net Framework Data Provider. It may not be installed.
After googling it, I found that I had to add the following to my web.config:
<system.data>
<DbProviderFactories>
<remove invariant="System.Data.SqlServerCe.4.0" />
<add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</DbProviderFactories>
</system.data>
Which I did. I am now stuck with the following error that I cannot seem to get rid of:
Failed to find or load the registered .Net Framework Data Provider.
The error occurs when I try to access the membership database through the Membership class.
What am I doing wrong? I've posted my entire web.config file below.

The solution is that SQL Server Compact is not a native part of the .NET framework, but must be installed separately. This installer can be downloaded here: http://www.microsoft.com/en-us/download/details.aspx?id=17876
I've downloaded an example how we canimplement Membership Provider in Entity Framework code first from Imar Spaanjaars's blog
http://imar.spaanjaars.com/563/using-entity-framework-code-first-and-aspnet-membership-together
But at the moment I can't open any site until I register or login.
How can I as in template MVC 3 have access to all sites?

That example has two things that force authentication:
The default controller/action in Global.asax.cs is Home/Index. If you don't specify a controller/action in your request then it will default to Home/Index. Now check out HomeController.cs::Index
HomeController.Index has the [Authorize] attribute which requires authenticated sessions (i.e. where HttpContext.User.Identity.IsAuthenticated == true).
The only controllers/actions that allow for un-authenticated requests are Account/* and Home/About.
Remove the [Authorize] attribute from HomeController::Index and you'll get to it without requiring authentication.
I'm running the MVC3 RC2 with Razor in my VB.NET application. I can't for the life of me figure out why I'm getting highlight errors in my markup.
