Entity Framework 6 Oracle DbConfiiguration

不想配置Entity Framework 6的App.Config文件时，要重写DbConfiguration，还要AppConfig当中的所有关于EntityFramework的所有配置项删除，不然DbConfiguration不会生效。

public class MyDbConfiguration : DbConfiguration
{
    public InMindDbConfiguration()
    {
            SetDefaultConnectionFactory(new OracleConnectionFactory());
            SetProviderServices("Oracle.ManagedDataAccess.Client", EFOracleProviderServices.Instance);
            SetProviderFactory("Oracle.ManagedDataAccess.Client", new OracleClientFactory());
    }
}

[DbConfigurationType(typeof(MyDbConfiguration))]
public class MyDbContext : DbContext
{
    private const string ConnectionString = "User Id=xxx;Password=xxx;Data Source=Oralce";
    static MyDbContext ()
    {
        //配置TNS路径
        //OracleConfiguration.TnsAdmin = @"c:\odtnet\network\admin";

        //配置初始化器
        //Database.SetInitializer(new MyCreateDatabaseInitializer());
    }
    public MyDbContext() : base(ConnectionString)
    {
        
    }
}
