This section describes how you can use the Data Access Application Block to develop applications. It first explains how to configure the application block and incorporate it into your applications. Next, it explains how to use the application block for specific scenarios, such as retrieving a single item or using a DataSet object to retrieve multiple rows. Lastly, it provides more information about topics such as connection management, parameter handling, and handling exceptions.

This section assumes that you are using the application block in its original state, without extending it. (To learn how to add functionality, see Extending and Modifying the Data Access Application Block.) This section includes the following topics:

All application blocks ship as binary assemblies and as source code. If you want to use the source code, you must compile it. To learn how to compile the Enterprise Library source code, see Building Enterprise Library from the Source Code.


Note:
The Data Access Block cannot be used in applications that target the .NET Framework 4.0 Client Profile. It can only be used in applications that target the full .NET Framework 4.0 profile. For information about profiles in the .NET Framework 4.0, see .NET Framework Client Profile on MSDN. For information about changing the targeted profile, see How to: Target a Specific .NET Framework Version or Profile on MSDN.
