Recently I was engaged in a project where by the customer wanted to push messages to the mobile application from their website.

While developing applications, it is quite common that you are required to produce formatted output. This is a common scenario for any developer whether you develop console application, web application or Mobile application. With C# 6 onwards Microsoft introduced a special character called interpolation operator ($) to help developers easily manipulate the string literals.
In this article, I am briefly explaining the interpolation operator with the help of couple of examples.
Let us consider the example of adding two numbers and print their sum as the output. Very simple example. The below is the old (ugly) way of doing this in C# with ASP.Net.
int a = 2, b = 3, sum = a + b;
Response.Write("The sum of " + a + " and " + b + " is " + sum);

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.

Console.WriteLine("Quotient is " + result.Item1);
Console.WriteLine("Remainder is " + result.Item2);
In this article, I am going to explain how to create SharePoint hosted Add-In using Visual Studio and how to deploy this Add-In to SharePoint 2016 on premise version.
Building a successful Add-in include two steps. First you need to author your Add-In using Visual Studio. Once you build your Add-in you need to deploy this Add-In to a SharePoint environment and test the Add-In. You can deploy the Add-In to SharePoint online or to the on-premise SharePoint. This article covers the deployment of Add-in to the On Premises version.
Step 1: Create Your Add-In
Open Visual Studio as administrator. From the Menu, select File -> New -> Project
In the new Project Dialog box, from the left menu, expand Visual C#, then Office/SharePoint and choose SharePoint Add-in. Also you can use the search box in the top right corner to locate the Add-n Project template.
Managed navigation in SharePoint allows you to define SEO friendly URLs to SharePoint pages. This feature helps your visitors remember the URLs and also increases your page ranking in search engines.

Since Visual Studio 2017 is released, I wanted to try it as usual. But I found, there is no ISO available for Visual Studio 2017. But there is a beautiful guide available that explains how to create an offline installer for Visual Studio. You can find the document in the below link
When you create a project in Visual studio 2015, the first thing you need to choose is the location for the project. By default the location is under the documents which is under the system drive. The below screenshot shows the new project dialog with the default location.
