The following option can be added to web.config to redirect an older assembly to the
.dll fo a newer assembly.

This works even if the older control is embedded into a third-party module.
This will also work to correct AjaxControlToolkit version ambiguity between earlier versions and asp.net 3.5

This example will take the Q3 2008 version of the Telerik.Web.UI and redirect all controls to the Q1 2009 assembly

    
            <runtime> 
        
               <dependentAssembly> 
        
                  <assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4"/> 
        
                 <bindingRedirect oldVersion="2008.3.1125.20" newVersion="2009.1.311.20"/> 
        
               </dependentAssembly> 
        
            </runtime>

6 lines of code to prevent many hours and frustration.

Hello Cliff,

Thank you for sharing your code.

You can make your BindingRedirect universal using the following approach:

    
            <runtime> 
        
              <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
        
                <dependentAssembly> 
        
                  <assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" /> 
        
                  <bindingRedirect oldVersion="2008.1.1.20-2009.4.2000.20" newVersion="2009.1.402.20"/> 
        
                </dependentAssembly> 
        
              </assemblyBinding> 
        
            </runtime>
