Remarks
Unlike DbProviderFactory, which is purely a factory for provider-specific objects such as DbConnection, DbDataSource hands out open connections to specific databases, encapsulating all the information needed to connect to a database. Depending on how the DbDataSource was configured, the connections it hands out may be pooled.
Constructors
| DbDataSource() |
Initializes a new instance of the DbDataSource class. |
Properties
| ConnectionString |
Gets the connection string of the database represented by this DbDataSource. The exact contents of the connection string depend on the specific data source for this connection. |
Methods

Returns a DbBatch that's ready for execution against the DbDataSource. |
| CreateCommand(String) |
Returns a DbCommand that's ready for execution against the DbDataSource. |
| CreateConnection() |
Returns a new, closed connection to the database represented by this DbDataSource. |
| CreateDbBatch() |
Returns a DbBatch that's ready for execution against the DbDataSource. |
| CreateDbCommand(String) |
Returns a DbCommand that's ready for execution against the DbDataSource. |
| CreateDbConnection() |

| Dispose() |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources asynchronously. |
| Dispose(Boolean) |
Called by the Dispose() and Finalize() methods to release the managed and unmanaged resources used by the current instance of the DbDataSource class. |
| DisposeAsync() |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources asynchronously. |
| DisposeAsyncCore() |
Performs application-defined tasks associated with freeing, releasing, or resetting managed resources asynchronously. |

| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| OpenConnection() |
Returns a new, open connection to the database represented by this DbDataSource. |
| OpenConnectionAsync(CancellationToken) |
Asynchronously returns a new, open connection to the database represented by this DbDataSource. |
| OpenDbConnection() |
Returns a new, open connection to the database represented by this DbDataSource. |
| OpenDbConnectionAsync(CancellationToken) |
Asynchronously returns a new, open connection to the database represented by this DbDataSource. |
