How to get ASP.NET MVC Preview 4 to run with .NET SP1

As you probably know by now (i.e. from Phill's blog), however both Routing and Abstractions are. MVC Preview 4, however, has its own version of both assemblies.

In order to get MVC to use the new RTM bits of both assemblies (and avoid weird side-by-side errors), you just need to add the following binding redirect to the web.config file:

    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Abstractions" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="0.0.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Routing" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="0.0.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

The other two redirects are added automatically by a Dynamic Data website, so I figured out it's better to put them there too :)
