Microsoft has created Entity Framework (short form EF) for helping developers to automate database related operations in C#, VB, C++ and other programming languages. Due to EF developers are not needed to do the lengthy ADO.NET programming as EF takes all its care.
EF helps developers in many ways like:
1. Less database related codes.
2. Fast development of projects.
3. Better transaction.
4. Testability improvements.
Here in this tutorial I will help you to get stated with Entity Framework.
In websites we see the feature of sending SMS to customer’s mobile no. This is done for a no of reasons like sending one time password (OTP), authentication, marketing and more. You can also add SMS sending feature in your website very easily using PLIVO (https://www.plivo.com/) which is a Global SMS & Voice calls service.

OAuth is an open standard to authorize application to access user data from online servers without sharing user’s credentials. It is specifically designed to work in ‘Hypertext Transfer Protocol (HTTP)’. OAuth provides ‘access tokens’ to applications when the user gives approval, and through this access token the application can access the user’s data in online servers.
Today nearly all top service providers like amazon, google, yahoo, twitter , facebook etc support OAuth and allow applications to access users data stored in their servers (on the approval of the users). The first version of OAuth known as OAuth 1.0 became live in April 2010 then the next version i.e. OAuth 2.0 came in October 2012. (more…)
Authentication is a process of identifying a person. It is commonly done through the use of login page which asks a user to enter his username and password. In ASP.NET websites you can do the authentication of a user by matching his user id and password with the one stored in the database. If both his username and password matches only then he is allowed to view secured areas of the website. (more…)
