oracle全托管驅動Oracle.ManagedDataAccess

終於見到了oracle官方的托管驅動，發布只需一個6M多的dll，支持EF 支持分布式事務

附：

1. Download ODP.NET, Managed Driver .zip file to a directory for staging the install.
2. Unzip the download to expand its contents into the target directory.
3. Run configure.bat to GAC and configure machine.config for ODP.NET, Managed Driver.
4. Create a new Visual Studio 2010 console application project for C#.
5. Add Oracle.ManagedDataAccess.dll as a reference to the project.
6. Replace the contents of Program.cs with the following C# code. Notice that the namespace of ODP.NET, Managed Driver (Oracle.ManagedDataAccess.*) is different from the namespace of ODP.NET, Unmanaged Driver (Oracle.DataAccess.*).
   

   // C#
   using System;
   using Oracle.ManagedDataAccess.Client;
   using Oracle.ManagedDataAccess.Types;
   
   namespace Connect
   {
     class Program
     {
       static void Main(string[] args)
       {
         try
         {
           // Please replace the connection string attribute settings
           string constr = "user id=scott;password=tiger;data source=oracle";
   
           OracleConnection con = new OracleConnection(constr);
           con.Open();
           Console.WriteLine("Connected to Oracle Database {0}", con.ServerVersion);
           con.Dispose();
   
           Console.WriteLine("Press RETURN to exit.");
           Console.ReadLine();
         }
         catch (Exception ex)
         {
           Console.WriteLine("Error : {0}", ex);
         }
       }
     }
   }
