Have a quick sneak peek at the future of C#.

Do you know all the features available in the current latest release of C# 7?
Do you know all the potential features who might make it into C# 7.3, C# 8 and beyond?

At the .NET Cambridge community, I introduced all the C# 7 features and quickly introduced all the potentially upcoming features in the future versions of the language.

Here I share all the slides I used during my presentation.

C# 7.0 up to C# 7.2 introduced the following features:

• Inline Out Variable
• Tuples
• Pattern Matching in Is Expression
• Pattern Matching in Switch Statement
• Local Functions
• Throw Expressions
• Binary Literals and Digit Separators
• Expression bodied members
• ValueTask<T>
• Ref returns and locals
• Async Main
• Default expressions
• In Parameters
• Ref readonly
• Readonly struct
• Ref struct
• Private Protected access modifier
• Non-Trailing named arguments

What's baking for the future of C#? 

• Ref local assignment expression
• Ref this for extension methods
• by value vs `in` overload tiebreaker
• Attributes on auto-implemented properties
• New generic constraints
• Operators == and != for Tuples
• IEnumerable<T> in params
• Target typed stackalloc initializers
• Utf8 string literal
• Nullable References
• Records
• Slicing with Ranges
• Native Number Types
• Fixed sized buffers
• Negation of if/while condition
• Extension everything
• Async Enumerable and Async Dispose
• Query foreach
• Null-conditional await
• Null-coalescing assignments
• Default implementation in interfaces
• Dictionary literals
• Constant patterns
• is not pattern?
