    I have performed a kendo upgrade on my MVC application and it has created problems that i need to resolve.

    My upgrade was from version 2016.3.1118 to 2017.3.1026

    Prior to upgrade wizard running i tried the compatibility checker but got an error saying it was incompatible with MVC projects, then it crashed my instance of VS2017.

    So on reloading VS i just did the upgrade which took over an hour and the Upgrade Wizard Log indicated a success. The latest kendo files were installed and i changed my bundles.config to reference the new folders. I also checked my kendo reference was also now the latest version. The editor templates had also been updated. I also updated the reference to Telerik.UI.for.AspNet.Mvc5 version in packages.config.

    Looking at a few previous posts on the forum i updated my bundles file to include an additional 2 files...

    bundles.Add(new ScriptBundle("~/bundles/kendo").Include(

    On running my application post upgrade i am not getting any data to display nor am i getting many of the links to work. There are also some CSS issues but these are not a priority till i get the functionality working again.

    What steps should i take to try and determine what is wrong? It would seem that my jquery/ typescript files are not running or something is conflicting with them? I do see the main ones loading in the Network tab of Developer Tools, and in the Console tab i see a number of errors that do not appear in the original application. (image attached)

    Any help with this would be much appreciated...

    Hello Mark,

    The successful upgrade of a Telerik UI for ASP.NET MVC version depends on two major steps:

    I have inspected the provided bundle snippet and noticed that kendo.web.min.js is include and actually this is not needed. Please try to modify the bundle as follows:
    bundles.Add(new ScriptBundle("~/bundles/kendo").Include(

    Also, please make sure that the Kendo bundle is referenced after jQuery and that the references are placed in the <head> element in the Layout file:

    Please try the above and let me know if this works.

    I am looking forward to hearing from you.

    Progress Telerik
