    Hi, my web application working fine previously. Not sure why suddenly so many errors come out when I try to [Build Solution]. 

    1) Error 191 Could not load file or assembly 'AjaxControlToolkit, Version=4.1.7.123, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

    2) Error 404 'ConfigurationSettings' is not declared. It may be inaccessible due to its protection level. C:\Projects\MyFirstProject\App_Code\DBjob.vb 11 29 C:\...\MyFirstProject\


    3) Error 405 Type 'Exception' is not defined. C:\Projects\MyFirstProject\App_Code\DBjob.vb 69 21 c:\...\MyFirstProject\


    Error 517 Maximum number of errors has been exceeded. C:\...\MyFirstProject\

    Usually there is a syntax error in a class library.  When the library  build fails the errors cascade to the parent projects.  Simply building one project at a time.  Build the child libraries first.
