Quick Start (Base64): Creating relationships between resources using the web service API

The following C# code example creates a relationship between two resources in the LiveCycle repository. (See Creating Resource Relationships.)

/* 
    * Ensure that you create a .NET client assembly that uses  
    * base64 encoding. This is required to populate a BLOB  
    * object with data or retrieve data from a BLOB object. 
    *  
    * For information, see "Invoking LiveCycle using Base64 Encoding"  
    * in Programming with LiveCycle
