Could not load file or assembly 'Telerik.OpenAcces

Hi Dear

 I use "Telerik.OpenAccess" and then I removed it from my project.
 Every time that I run my project for first time I got this error :

Could not load file or assembly 'Telerik.OpenAccess, Version=2010.3.1110.3, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342' or one of its dependencies. The system cannot find the file specified.

and when I refresh site it will work correctly.However there is no refrense to Telerik.OpenAccess.

Best Regards

Don't forget to FTP the  C:\Program Files (x86)\Telerik\OpenAccess ORM\bin\Telerik.OpenAccess.dll  to your website bin directory. 

Hi  Serge,
I have the same problem,so where should I find the line <Import Condition="Exists('$(MSBuildExtensionsPath)\OpenAccess.targets')" Project="$(MSBuildExtensionsPath)\OpenAccess.targets" />
to delete,
I attache a VB library that contient the telerik reporting according ti m site web but I DONT USE TELERIK.OPENACCESS !!!
Thank you 

Hello Berrabah,

 I am not sure I completely understood you question? Are you using Telerik Reporting and not OpenAccess. If that is the case, then please just remove the reference in your project to the Telerik.Reporting.DatabaseSession.dll. Otherwise, I would like to have more detailed information about your project setup so we can find the actual cause for your problem.

Hi,
I am getting the same error that 'could not load type 'Telerick.openaccess' 
Aslo, I checked for the entry 
<Import Condition="Exists('$(MSBuildExtensionsPath)\OpenAccess.targets')
This entry si not there in my project file.
still its giving me problem.

Hello Aruna,

Could you please provide us with additional information regarding the setup you are using on your side? If case of Reporting application have you tried the resolution suggested in the previous post? Do you have any Telerik OpenAccess ORM references in your projects or deployed under the Bin folders?

We are looking forward to hearing from you.

Kind regards,

Hello Aruna,

Thank you for the provided details.

In order for us to recommend the most proper solution, could you describe what are you trying to achieve - to stop using OpenAccess ORM in this project or to make it work together with Telerik Reporting and Sitefinity? Also, could you send us the entire error message that you are receiving "Cannot load type...", especially the particular assembly version that is mentioned? 

I am looking forward to your feedback.

Hi Aruna,

It seems that the version of Sitefinity and the version of OpenAccess ORM you are using are compatible. Therefore, there are a few options for the source of this exception:
1. Verify that the same, correct version of OpenAccess is referred in all the projects that have OpenAccess references, and in all of them you are referring as a minimum Telerik.OpenAccess.dll and Telerik.OpenAccess.35.Extensions.dll.
2. Verify that there aren't any old references to Sitefinity 5.1, in case you have ever used it, as it requires OpenAccess 2012.2.628.2
3. Check your web.config files for direct references to Telerik.OpenAccess assembly, as it is possible for such references to exist in many scenarios. If there are any, please update the version.

In any case, please add the Telerik.OpenAccess.35.Extensions assembly reference to your application as well - it is required together with the Telerik.OpenAccess assembly in each project using the OpenAccess entities.

If neither of those actions resolve your issue, it is also an option for you to send us your application so that we can analyze it provide a solution. Note that this would happen privately, not through the public forum, so please let us know and we will convert your post into a feedback ticket for that purpose. I recommend that as the fastest way to track and resolve the problem.

I am looking forward to your feedback.

Took me forever to figure this out, it's not the Telerik.OpenAccess assembly​ (the error message itself is confusing)-- simply remove Telerik.Reporting.OpenXmlRendering.dll from your BIN. 

I am getting this error for every aspx page despite the fact that I have completely uninstalled Telerik Data Access and removed all references to it from the solution.  Where is this attempt to load Telerik.OpenAccess coming from? I do not need it, do not want it, and your company has stopped developing it.  I need it to get OFF my computer.

 

Well so the problem was a stale DLL in the bin subdirectory.  Killed the bin, back to normal.  Painful.
