Auto-Property Initializers

nameof expression

Expression Bodied Function & Property

C# 7.0

Tuples (with types and literals)

Minimizing OUT

Local FunctionsLocal functions would have the same capabilities as normal methods but would only be scoped to the block they were declared in.

Readability Improvement with Literals

Is-expressions with patterns

Switch statements with patterns

• You can switch on any type (not just primitive types)• Patterns can be used in case clauses• Case clauses can have additional conditions on them
