Microsoft Visual Studio 2013 and Your App Store

Following release of the revolutionary Win8.1 preview, we need some special apps and features. So for that purpose Microsoft also released Microsoft Visual Studio 2013.

Some Key Features of Visual Studio 2013

Visual Studio Languages

  • .NET FrameWork 4.5.1 : Now, when you compile an app that targets the .NET Framework 4.5.1, you can add binding redirects to the app configuration file if your app or its components reference multiple versions of the same assembly.
  • Visual C++: New features include compiler and STL support for these features:
  1. Default template arguments for function templates
  2. Delegating constructors
  3. Explicit conversion operators
  4. Initializer lists/uniform initialization
  5. Raw string literals
  6. Variadic templates

JavaScript

Block Scoped Variables

You can use the new let and const keywords to declare variables for which the scope is limited to the block in which they're declared. See let Statement (JavaScript) and const Statement (JavaScript).

Container Object

You can create a collection of unique objects by using the Set Object (JavaScript) object, and you can create a collection of key/value pairs by using Map Object (JavaScript) or WeakMap Object (JavaScript).

Your App Store and Visual Studio 2013

Here you can look at the improvements in Windows 8. The main point here is the Start Button in the Taskbar. Another point is the App Store, it has many updated apps. The Windows user experience continues to evolve, and it's getting easier to develop, test, and submit apps to the Windows Store.
