use ADO.NET via Context.Database

The DbContext.Database property allows us to perform ADO.NET as sown below. 

 //Execute Reader

    using (var ctx= new DatabaseContext())
    using (var cmd= ctx.Database.GetDbConnection().CreateCommand())
    {
        cmd.CommandText = "SELECT * From Table1";
        cmd.Database.OpenConnection();
        using (var result = command.ExecuteReader())
        {
            // do something with result
        }
    } 

//Execute SP

using (var ctx= new DatabaseContext())
    using (var cmd= ctx.Database.GetDbConnection().CreateCommand())
    {
               cmd.CommandText = "dbo.someSP"
                _dataContext.Connection.Open()
                cmd.CommandType = CommandType.StoredProcedure

                Dim param As DbParameter = command.CreateParameter()
                param.DbType = DbType.Int16
                param.ParameterName = "@param1"
                param.Value = 'value1"
                cmd.Parameters.Add(param)

                param = cmd.CreateParameter()
                param.DbType = DbType.DateTime
                param.ParameterName = "@param2"
                param.Value = "value2"
                cmd.Parameters.Add(param)

                cmd.ExecuteNonQuery()
                _dataContext.Connection.Close()
        }
    }
