[Solved] EntryPointNotFoundException

[quentinjs]

Here is my call of the Grid, its very simple, but I can't seem to get it to work.  It keeps raising 
that EntryPointNotFoundException

<% Html.Telerik().Grid(Model)
        .Name("GroupGrid")
        .Columns(columns =>
             {
                 columns.Bound(c => c.GroupId);
             })
        .Sortable()
        .Pageable()
        .Render();
%>

Thanks for any help.

If the project references any third-party libraries that are compiled against an earlier ASP.NET MVC, 
add the following bindingRedirect element to the Web.config file in the application root 
under the configuaton section:

This will work for MVC 2, but if your using MVC 3 then use the 2nd one below:

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Mvc" 
          publicKeyToken="31bf3856ad364e35"/>
      <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
    </dependentAssembly>
  </assemblyBinding>
</runtime>

For MVC 3

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
