porque no lo compilas desde VSNET?
ojo que el conectionstring está dentro del web config, así que quizás ese puede ser el problema, porque la clase está leyendo otro

  Subject: [aspx_espanol] Creacion de Dll´s


  Que tal, aqui nuevamente planteando mis dudas!!!!

  Fueron de gran ayuda los consejos que me dieron
  anteriormente acerca de la creación de dlls para
  mis procedimientos. Use la herramienta llamada
  LLBLGen, para que me generara las clases y todo 
  hasta aqui esta bien (por cierto, esta muy padre la
  herramienta). Pero al momento de generar la dll me
  envio varios errores, no he podido ubicar que puede
  ser, ya que en el codigo no identifico que estaria mal
  y solo me indica error en los objetos del
  SQLClient(SqlConnection, SqlByte, SQLCommand,etc),
  espero puedan ayudarme con este problemita, gracias.

  Para la creacion de la dll, la realizo desde el prompt
  y usando el vbc con los sig. parametros

  C:\WINNT\Microsoft.NET\Framework\v1.0.3705\vbc
  /r:system.web.dll /t:library clsCat_estatus.vb

  Y unos de los errores, son los sig:

  C:\ejemplosnet\clsCat_estatus.vb(157) : error BC30002:
  Type 'SqlByte' is not defined.
                  Dim byFiEstat_idTmp As SqlByte = Value
                                         ~~~~~~~
  C:\ejemplosnet\clsCat_estatus.vb(166) : error BC30002:
  Type 'SqlString' is not defined.
          Public Property [sFcDescripcion]() As
  SqlString
                                               
  ~~~~~~~~~
  C:\ejemplosnet\clsCat_estatus.vb(170) : error BC30002:
  Type 'SqlString' is not defined.
              Set(ByVal Value As SqlString)
                                 ~~~~~~~~~
  C:\ejemplosnet\clsCat_estatus.vb(171) : error BC30002:
  Type 'SqlString' is not defined.
                  Dim sFcDescripcionTmp As SqlString 
  Value
                                           ~~~~~~~~~
