Pattern-based C#: if it quacks like a duck…

C# is a strongly typed programming language, used to communicate expectations in a statically verifiable fashion across the .NET ecosystem. There is a set of language features that can be enabled by satisfying a particular shape rather than inheritance or interface implementation.

In this session we look at compiler-recognized patterns such as:

• using custom types in foreach
• applying await to custom types
• tuple-like deconstruction
• implicit Index and Range support
• collection initializers and expressions for user-defined types

Join this live coding session for a deep dive into pattern-based features in C# and how to make reusable types more convenient and idiomatic to consume.
