Step 4: Testing the WCF Data Service

To see if your application is really using the WCF Service data access class:

  1. With your project open, go to the Visual Studio menu and select File | Open | File.

  2. Navigate to the following folder:

    C:\Program Files\MM .NET Framework 2026\MM .MET Framework WCF

  3. Open the mmDataAccessWCFSql.cs file (or mmDataAccessWCFOracle.cs, and so on).

  4. Set a breakpoint in the FillDataSet() method of the WCF Service data access class, then run your application. Whenever you retrieve data you should hit the breakpoint.
