I’m writing a application, where I also work with ADO.NET:

using System.Data.OracleClient;

Code example:

try{
       OracleConnection myOracleConnection = new OracleConnection(connectionString);
       myOracleConnection.Open();
       OracleCommand command = myOracleConnection.CreateCommand();
       ...
   }

It works but I got warnings:

Warning 3   'System.Data.OracleClient.OracleCommand' is obsolete: 'OracleCommand has been deprecated. http://go.microsoft.com/fwlink/?LinkID=144260'

Whats other options do I have? “Microsoft recommends that you use a third-party Oracle provider.” —

    You should be using ODP.NET (Oracle Data Provider for .NET)

    Oracle Data Provider for .NET (ODP.NET) features optimized ADO.NET
    data access to the Oracle database. ODP.NET allows developers to take
    advantage of advanced Oracle database functionality, including Real
    Application Clusters, XML DB, and advanced security. The data provider
    can be used with the latest .NET Framework 4 version.

    ODP.NET makes using Oracle from .NET more flexible, faster, and more
    stable. ODP.NET includes many features not available from other .NET
    drivers, including a native XML data type, self-tuning, RAC-optimized
    connection pooling, promotable transactions, and Advanced Queuing.
