Thank you for your help

i change manually in the web.config newVersion="3.5.0.0" to newVersion="4.0.0.0" and the connexion

<dependentAssembly>
< assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
< bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="4.0.0.0" />
