oracle全托管驱动Oracle.ManagedDataAccess

终于见到了oracle官方的托管驱动，发布只需一个6M多的dll，支持EF 支持分布式事务

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);
         }
       }
     }
   }
