Msg 6522, Level 16, State 1, Procedure spChamarWsConsultaCPF, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "MinhaProcedure":

Please see inner exception for more information. ---> System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.
System.IO.FileLoadException:
