Hello -

I have a Web API project and ever since I installed the Telerik AJAX controls, I'm getting an error whenever I try to browse to the Web API URL. It was working previously. Also, I'm not using the RadUploadHandler anywhere, so I'm not sure where this is coming from. Here is the error I'm getting:

Server Error in '/' Application.

Could not load file or assembly 'Telerik.Windows.RadUploadHandler, Version=2011.2.920.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

Hello Jeff,

Indeed the Telerik.Windows.RadUploadHandler assembly is part of the Silverlight suite of controls and it is usually used to create an UploadHandler deriving from the RadUploadHandler class. Can you please examine your solution to see if it the RadUploadHandler class is used somewhere to create an HTTP handler?

If you can't find a reference to the assembly or if the class isn't used in your solution, you can send us your project/solution so that we can investigate the case further on our side.

Kind regards,
Tina Stancheva
