In general , a "Factory" class has only static methods, so you can't
isntantiate it.

It's called the "Factory Design Pattern"

Check the msdn documentation for that specific class, to see if its static
methods only.

Hello Rohit,

DbProviderFactory is an abstract (MustInherit in VB) class. It means you can
not create an instance of such a class. You are able to create instances of
"concrete" implementations that derive from DbProviderFactory:

System.Data.Odbc.OdbcFactory
System.Data.OleDb.OleDbFactory
System.Data.OracleClient.OracleClientFactory
System.Data.SqlClient.SqlClientFactory
