Quick Start (MTOM): Unlocking an encrypted PDF document using the web service API

The following C# code example unlocks a password-encrypted PDF document named EncryptLoan.pdf. (See Unlocking Encrypted PDF Documents.)

    * Ensure that you create a .NET project that uses  
    * MS Visual Studio 2008 and version 3.5 of the .NET 
    * framework. This is required to invoke a  
    * LiveCycle service using MTOM. 
    * For information, see "Invoking LiveCycle using MTOM" in Programming with LiveCycle
