Unable to load Telerik

[Rhys]

Hello,

I am an old VBScript and PHP programmer and have never dealt with ASP.NET, so please take it easy on me.  I am simply trying to migrate website from an Azure server to an AWS instance.  I was able to install the Telerik and change the assembly references in web.config, but now I'm getting this mismatch error and cannot figure out why.  I have updated my versions and PublicKeyTokens everywhere I can find, and it still isn't working.  Any insight would be greatly appreciated.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Could not load file or assembly 'Telerik.Web.UI, Version=2017.1.118.45, Culture=neutral' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Source Error:


An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

,

Thank you for your response.  I believe you misunderstood my situation as the post you referenced is talking about publishing on Azure, and I am migrating away from Azure to Amazon.  I did walk through the various troubleshooting steps described in that post, as well as the final solution and it did not fix my issue.  I did manage to fix my issue by referencing version 2017.1.118.40 instead of 2017.1.118.45.  I am not sure why this fixed the issue, but it did.  Thanks again for your help.

Hi Rhys,

Most probably there have been some remaining references targeting .NET 4.0 which were causing the errors when you tried to refer DLLs targeting .NET 4.5 (e.g. in the *.proj file of the application). I am glad you have managed to find a suitable solution for your scenario and the application is working properly now.
