Reading NS records in C# using ARSoft packages

In this post you will learn about reading NS records in C# using ARSoft packages. This package is handy to read domain NS records. Here's a sample code which will help:

using System;
using System.Linq;
using ARSoft.Tools.Net;
using ARSoft.Tools.Net.Dns;
namespace ConsoleApp14
{
    class Program
    {
        static void Main(string[] args)
        {
            var dnsMessage = DnsClient.Default.Resolve(DomainName.Parse("learninhindi.com"), RecordType.Ns);
            var nsrecords = dnsMessage.AnswerRecords.OfType<NsRecord>();
            foreach (var record in nsrecords)
            {
                Console.WriteLine(record.NameServer.ToString().TrimEnd('.'));
            }
            Console.ReadKey();
        }
    }
}


Here's the output of the above code:

Attended Microsoft MVPs Open Day 2015 in Bangalore

Image
It was another year I attended Microsoft MVPs Open Day event in Bangalore, last time it was in Goa.

||For those who don’t know what MVPs Open Day is
Every year Microsoft MVP Award Program organizes an event dedicated for MVPs only. In such event MVPs gathered together from different cities (South Asia MVP region includes India, Nepal, Bangladesh etc countries). Such events feature technical sessions designed to enhance the community's understanding of new Microsoft products, existing tools and new techniques. But MVPs like me don't come to learn just from Microsoft teams, we present during Open Days, which allows MVPs to    i) share real-world knowledge of Microsoft technologies aka "MVP to MVP" sessions    ii) network with fellow MVPs in person and this helps understand community more closely    iii) enjoy with fellow MVPs

I had a great time with MVPs and Lead. I would like to thank Biplab and Gandharv for organizing this event beautifully.

Entity Framework's Database Seed Method

Image
The Entity Framework can automatically create/update/drop databases when the application runs. We can specify that, this should be done every time application runs or only when the model is out of sync with the existing database or in other word it runs whenever model changes. You spent time to insert records in database and when you made any changes in model, Entity Framework deletes your database as well as records.
