What's  New in Visual Studio 2017 RC We have many new as well as improved features and experiences in Visual Studio 2017  to make you more productive at things you do every day IntelliSense  IntelliSense comes enhanced with added filtering that makes it much easier to use . Filtering makes long lists much more manageable. With features like Camel Case search you only need to type in the 2 letters in capitals for IntelliSense to appropriately filter results for you that match 2 different words with those letters capitalized. IntelliSense is also smarter now; it will select the best matching result from the list instead of simply picking the top result. Navigation Navigation .

1. MAKE A PLAN BEFORE YOU START WRITING YOUR CODE OOP is a great way to compartmentalize software code, but you can get lost in the details if you don’t have a good plan. It’s a good idea to use a tool such as  Visio  to plan out each class and its properties and methods, for example, before you start coding. Planning ahead ensures the organization of your code is a success before you even write the first line of code. When you’re planning ahead, identify each component of your application and plan methods and properties that would make up a specific class. If you have a customer class, identify what information you need to store for a customer. You might need the customer’s address, name, phone number, and gender. These would be properties of the customer class. Planning helps you identify the components needed for your software, so you won’t forget them and have to go back and refactor your code. 2. DON’T FORGET THE DATABASE Every dynamic web application needs a da...

What is Claim ? A claim in the world of authentication and authorization can be defined as a statement about an entity, typically a user. A claim can be very fine grained: Ram is an admin Ram’s email address is Ram@yahoo.com Ram lives in Mumbai Tom’s allowed to view sales figures between 2009 and 2012 Tom’s allowed to wipe out the universe Claims originate from a trusted entity other than the one that is being described. This means that it is not enough that Tom says that he is an administrator. If your company’s intranet runs on Windows then Tom will most likely figure in Active Directory/Email server/Sales authorisation system and it will be these systems that will hold these claims about Tom.  The idea is that if a trusted entity such as AD tells us things about Tom then we believe them a lot more than if Tom himself comes with the same claims . This external trusted entity is called an  Issuer . The KEY in the key-value pairs is called a  Typ...
