Hi Everyone,

We previously used Siftefinity V5.1. Now we decided to update to a newer edition. After we intergated update patch into our development project, we encountered Assembly 'Telerik.Sitefinity.Utilities Version=5.1' not found issue.

Can someone give some suggestions on this? Thanks!

Hi,

The encountered problems is coming from the fact that you have some old references to assemblies in your project or you have modules/controls build with old assemblies.

I would suggest you in order to resolve the problem to open the project in Visual Studio, remove all Telerik references (For instance (Telerik.Web.UI, Telerik.Sitefinity and est.) then add them again ( by right click on References -> Add.. -> Browse -> Choose the bin folder of your Sitefinity project). After that build the project with the new assemblies and run it again.

If the problem still persist the other option that you have is to use bindingRedirect :

<runtime>

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<dependentAssembly>

<assemblyIdentity name="Telerik.Sitefinity.Utilities"

publicKeyToken="b28c218413bdf563"

culture="neutral" />

<bindingRedirect oldVersion="0.0.0.0-7.2.5320.0"

newVersion="7.2.5320.0"/>

</dependentAssembly>

</assemblyBinding>

</runtime>

Please find a sample above. Change the version with your current Sitefinity version. Place the code in web.config file right before the closing </configuration> tag. Then save the changes and try to access the backend of your website.
