Quick Start (MTOM):Adding a signature field using the web service API

The following C# code example adds a signature field, named SignatureField1, to a PDF document that is based on a PDF file named Loan.pdf. The PDF document that contains the new signature field is saved as a PDF file named LoanSig.pdf. (See Adding Signature Fields.)

    * 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
