I've installed the MVC framework and am trying to Kigg starter kit.  I get the following error when trying to browse to the application:

Could not load file or assembly 'System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.  What have I missed?

Thanks.

Source Error:

Line 38:       <assemblies>
Line 39:         <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
Line 40:         <add assembly="System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Line 42:         <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

Are the three assemblies:

• System.Web.Abstractions.dll
• System.Web.Mvc.dll
• System.Web.Routing.dll

in the application's bin folder?

(With preview #2 they are deployed side by side rather than in the GAC.) 

Please, give us some more information on that error.

Based on this what you've posted, are you sure that you're running this on March CTP of ASP.NET MVC? If you're running your example on December CTP, you'll most likely encounter this error, because complete functionality of ASP.NET MVC was not separated across these 3 assemblies, that were introduced in the March CTP:

System.Web.Abstractions
System.Web.Routing
System.Web.Mvc 

Easiest way to check that is to create new ASP.NET MVC project and open file HomeController.cs.  If public methods are decorated with [ControllerAction] ,  on your computer is installed December CTP of ASP.NET MVC. If that's not the case (if public methods inside controller class are not decorated with [ControllerAction] ) on your computer is installed March CTP.

Run following command on Visual Studio 2008 Command Promp

gacutil /i "C:\Program Files\Microsoft ASP.NET MVC Preview 2\Assemblies\System.Web.Abstractions.dll"

gacutil /i "C:\Program Files\Microsoft ASP.NET MVC Preview 2\Assemblies\System.Web.Mvc.dll"

gacutil /i "C:\Program Files\Microsoft ASP.NET MVC Preview 2\Assemblies\System.Web.Routing.dll"

The Kigg application is based on the ASP.NET MVC Preview 2, but the ASP.NET 3.5 Extension is just a CTP version.

The ASP.NET MVC road map update can be found here http://weblogs.asp.net/scottgu/archive/2008/02/12/asp-net-mvc-framework-road-map-update.aspx

So, you can just uninstall the CTP version and install the newer version called ASP.NET MVC Preview 2.
