When you create a data access client that uses the Data Access Application Block, you should perform the following steps:1. Set a reference to the Data Access Application Block assembly Microsoft.ApplicationBlocks.Data.dll.2. Add a using statement at the top of your data access client source file(s) to reference the Microsoft.ApplicationBlocks.Data namespace. All Data Access Application Block types are located within this namespace.3. Add a using statement to reference the System.Data and System.Data.SqlClient namespaces. The SqlHelper methods use various types from these namespaces as input and return parameters.4. Optionally, add a using statement to reference the System.Xml namespace. This is required only if you use the SqlHelper ExecuteXmlReader methods.
