C# New Version 7.0 Announced

There have been a number of changes, improvements and features made to C# 7.0 release of the next version of Visual Studio. In this article, I’m going to introduce the biggest features and changes, which have been announced. Thus, we all are quite familiar with the previous versions of C#, which are very useful language features to remove an unexceptional code and clean up our code.

Nowadays, programmers don’t want to suffer with error prone code or writing extra code --  they want an environment of convenient coding where they can get some simple and delightful code . We can see some features in C#,

• Portability
• Advanced runtime (garbage collection)
• Easy to adopt
• Native access
• Fast execution
• Reliability (type safety)
• Powerful features (reflection and dependency injection)
• Cutting edge (asynchronous programming)

C# 7.0 features come with the concise and shorter format for the wide use. C# 7.0 features are highly portable in a wide range of environments over the spectrum of mobile, Server computing, embedded and desktop. In this announcement, the features are highly expressive and it's easy to maintain the code. Here are a few new features in this announcement-

• Multi-value Returns
• Pattern Matching: Enhanced Switch Blocks
• Pattern Matching: Decomposition
• Tuple as a Mutable type
• Partial Class Enhancements
• Local Functions
• Binary Literals
• Ref Returns

There is No need to declare variables - In C# 7.0, there is no need to declare the variables, outside of the method from which, you are going to get it. It will be required only to add out before the variable and use it later on. Thus, it can be declared directly as the arguments such as a parameter.

Wildcards for ignoring Out parameters – This would be a great thing, as the idea of an out parameter, using wildcard* is of ignoring out parameters.

Pattern matching mechanism - This is a whole new mechanism, which will be introduced in C# 7, which for now will be used for checking  the objects in three types,

• Constant patterns of the form c (where c is a constant expression in C#), which tests that the input is equal to c.
• Type patterns of the form T x (where T is a type and x is an identifier), which tests that the input has type T and if so, it extracts the value of the input into a fresh variable x of type T.
• Var patterns of the form var x (where x is an identifier), which always matches and simply puts the value of the input into a fresh variablex with the same type as the input.
