Estou a começar a desenvolver uma aplicação ASP.NET com funcionalidades AJAX, no entanto, já estou com um erro:

Server Error in '/' Application.
Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileLoadException: Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)

Já alguém passou por este erro???

Primeiro deves veririficar se está a referenciar a dll ajaxcontroltoolkit.dll, vê se tens a dll na Bin da aplicação.
