//  .Net StockTrader Sample WCF Application for Benchmarking, Performance Analysis and Design Considerations for Service-Oriented Applications

//======================================================================================================
// The Settings class for the Business Service Layer (BSL).  Please note well that we only override the
// inherited settings (with the new keyword) becuase of the special case StockTrader BSL allows for running
// BSL in-process with the StockTrader Composite Web Application, vs. remote calls (and running the OPS in-process
// with the BSL, optionally).  You will NOT need to  do this for your services--your Settings class will be 
// much simpler, simply using the *inherited* global settings, and only specifying app-specific settings here.
