Microsoft.VisualStudio.Data.AdoDotNet Namespace

The AdoDotNet namespace contains a set a classes to complement native ADO.NET functionality.

Because ADO.NET natively provides a great deal of the functionality required to support a DDEX Provider, classes in this namespace provide default implementations of interfaces not overridden by a DDEX Provider.

Visual Studio 2008 provides in-the-box implementatins of the following:

• DataConnectionProperties class. Because ADO.NET provides a generic mechanism for building connection properties, the AdoDotNetConnectionProperties base class provides a complete implementation of this class.

• DataConnectionSupport class. Because all ADO.NET data providers must implement basic connection support, the AdoDotNetConnectionSupport base class provides a complete implementation of this class.

In addition to these base implementations that you can create directly from this object, this namespace also provides implementations of the following classes:

• DataObjectEnumerator

• DataSourceInformation

• DataParameter

• DataTransaction

• DataReader

• DataTableReader

• DataProviderObjectFactory

Classes

	Class	Description
	AdoDotNetConnectionProperties	Provides an implementation of the DataConnectionProperties class using the ADO.NET connection string builder base class (DbConnectionStringBuilder).
	AdoDotNetConnectionSupport	Provides a managed implementation of the DataConnectionSupport, DataCommand, and DataTransaction classes using the ADO.NET IDbConnection, IDbCommand, and IDbTransactioninterfaces, respectively; also provides a simple way to supply an implementation of the DataSourceVersionComparerclass.
	AdoDotNetDataReader	Provides an implementation of the DataReader class using an implementation of the ADO.NET IDataReader interface.
	AdoDotNetDataSourceInformation	Provides information about an ADO.NET data source in the form of properties passed as name/value pairs.
	AdoDotNetDataTableReader	Retrieves the contents of one or more DataTable objects in the form of one or more read-only, forward-only result sets.
	AdoDotNetObjectConceptMapper	Provides a default implementation of the DataObjectConceptMapper class for ADO.NET data providers.
	AdoDotNetObjectEnumerator	Provides an implementation of the DataObjectEnumerator class using the ADO.NET GetSchema API.
	AdoDotNetObjectIdentifierConverter	Provides an implementation of the DataObjectIdentifierConverter class using information supplied by an ADO.NET provider, including DataSourceInformation property values and the DbCommandBuilder, QuoteIdentifier, and UnquoteIdentifiermethods.
	AdoDotNetObjectItemComparer	Provides an implementation of the DataObjectItemComparer class that uses ADO.NET data source information to determine how to compare identifier parts.
	AdoDotNetParameter	Represents a data parameter that is derived from a data source command, or that is passed with a command to a data source whose underlying technology is ADO.NET.
	AdoDotNetProviderObjectFactory	Provides an implementation of the DataProviderObjectFactory class for DDEX Providers whose underlying technology is ADO.NET.
	AdoDotNetSchemaReader	Provides a means for obtaining the schema of the IDataReader object encapsulating the result set.
