    .Net 4.0 Support

    Reply Quote
    Hello
     
    I was wondering if there are any known issues with CuteLiveSupport in .net 4.0?
     
    We have been using it without issue with previous versions of the framewokr for some time but are experiencing problems after attempting to upgrade the rest of our website to .net 4.0.
     
    Thanks for any information you can provide.

    Hi mikeconfer,
     
    Try do the setting below in web.config after you upgrade to asp.net 4.0
     
    <httpRuntime requestValidationMode=″2.0″ />
     
    Regards,

    Thanks Ken
     
    Unfortunately that did not help. The error we have been seeing since the 4.0 upgrade is:
     
    Attempt by security transparent method 'CuteChat.RemoteDataProvider.GetPortalInfo(System.String)' to access security critical method 'CuteChat.ServiceClientInterface.RemoteChatServiceFactory.Create()' failed.

    Assembly 'CuteChat.AppCode, Version=5.0.0.0, Culture=neutral, PublicKeyToken=caec02264daa66c8' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model.  Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception

    Sorry for the double-post-
     
    Based on researching that error, we also attempted to add this to the web.config:
     
    <trust       legacyCasModel = "True"       level="Full" />
     
    with similar failure.

    Okay, I think I have determined how to work around the Security error.
     
    I am now seeing the following:
     
    System.ServiceModel.FaultException`1[[System.ServiceModel.ExceptionDetail, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]: Invalid object name 'CuteChat4_Portal'.
     
       System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +9464367
       System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +345
       CuteChat.ServiceClientInterface.ChatService.IRemoteChat.GetPortalInfo(String portalname) +0
       CuteChat.RemoteDataProvider.GetPortalInfo(String portalname) +86
       CuteChat.ChatDataManager.GetPortalInfo() +73
       CuteChat.ChatPortal.get_Info() +45
       CuteChat.ChatApi.GetCurrentPortalProperty(String propname) +155

    This latest error turns out to be a configuration issue on my side.
     
    In order to work around the Security MethodAccessExceptions I was seeing earlier,
    I had to put the following assembly attributes on all of the assemblies that called into
    your code:
     
    [assembly: SecurityRules(SecurityRuleSet.Level1)]
    [assembly: AllowPartiallyTrustedCallersAttribute()]
     
    Everything seems to be working now!

    It appears I was too quick in celebrating victory.
     
    What is occuring now under .net 4.0 is the chat window will display, it will provide visual indications to both the agent and the end user when the other party is typing, but no chat messages appear on screen.
