I am trying to load assemblies by referencing them in the web.config file.

I created a simple solution that contains a class library (DeploymentTest) and a web site (DeploymentTestWeb). The class library produces a dll, and is strongly named. The web site references this dll in the web.config file. I cannot get this reference to resolve. I have placed entries in both the <assemblies> section and the <assemblyBinding> section.
Code:
          <assemblies>
            <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
            <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
              <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
              <add assembly="DeploymentTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=4A419F2751ED4919"/>
          </assemblies>
Code:
    <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <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>
          <dependentAssembly>
              <assemblyIdentity name="DeploymentTest" 
                                publicKeyToken="4A419F2751ED4919"
                                culture="neutral" />
                  <codeBase href="..\DeploymentTest\bin\DeploymentTest.dll" Version="1.0.0.0"/>
          </dependentAssembly>

      </assemblyBinding>
    </runtime>
I cannot resolve the assembly, so I must be doing something wrong. Any ideas what I am missing?
