C# 7 - Return multiple values from methods
It was a long-awaited feature to return multiple values from a method. Developers used collection variables such as Array, ArrayList or Generic List to return multiple values from methods. Now with Visual Studio 2017 and C# 7, you can easily return multiple values with the help of Tuples.
In this article, I am going to explain how tuples can be used in C# 7 onwards to return multiple values.
Consider the following code from the console application. The method GetDivisionResults accepts two parameters namely number and divisor and returns two integers that are quotient and remainder.
static void Main(string[] args)
{
int number = 17;
int devisor = 5;
var result = GetDivisionResults(17, 5);
Console.WriteLine("Quotient is " + result.Item1);
Console.WriteLine("Remainder is " + result.Item2);

Securing sections in Web.Config
For ASP.Net applications, developers usually store lots of configuration data in the Web.Config, some of such settings can contain secured information such as connection strings, email settings, proxy settings etc. Storing credential information in Web.Config as plain text is a threat as this could lead to leak the information. Though the web server will not render web.config files to the visitors, you need to see there could be users, such as system administrators, back up operators, etc who have access to your server’s file system. Exposing secured information for such users is a threat and you need to protect your configuration data. The solution is to encrypt the sections in Web.Config and thankfully ASP.Net offers out of the box support for encrypting and decrypting the connection string placed inside Web.Config.
In this article I am going to demonstrate, how to encrypt/decrypt the connection string section in Web.Config, you can follow the same concepts to encrypt any other section in web.config. For the purpose of the article, I created an ASP.Net empty web application and added a default.aspx file. The project in solution explorer looks as follows.

Integrate Microsoft Translator into your ASP.Net application
In this article I am going to explain how easily you can integrate the Microsoft translator API to your ASP.Net application. Why we need a translation API? Once you published a website, you are opening a channel to the global audience. So making the web content available only in one language doesn’t cover all your audience. Especially when you are offering products/services it is important to provide contents in multiple languages. Users will be more comfortable when they see the content in their native language. How to achieve this, hiring translators and translate the content to all your user’s languages will cost you lot of money, and it is not a one time job, you need to translate the contents on the go. What is the alternative, we need to look for machine translation. Thankfully there are some translator engines available that gives you API level access, so that automatically you can translate the content and display to the user. Microsoft Translator API is an excellent set of web service APIs that allows developers to use the machine translation technology in their own applications.

Bundling and Minification in ASP.Net 4.5
Being a web developer in these days is challenging as well as interesting. With HTML 5 specifications in place, the browsers adding more client side capabilities. JQuery is playing a major role in today’s client side development. As a developer you cannot stay away from these things, you need to adapt these. At the same time you cannot develop (at least not practical as cost/time wise) all those client side scripts, you need to depend on third party JQuery plug-ins to bring attractive user friendly interfaces.

Site Map Provider using custom business objects
Recently one of the project I was in a situation to build navigation for line of business data, the existing system available was fully designed as object oriented and it connects with some database other than SQL server. While thinking about showing navigation controls to the user, it was not a good idea to drill through objects as it takes lot of resources and more number of connections.
