Async Streams – A Look at New Language Features in C# 8 

Work effectively without null references 

Using C# 8.0 in Core 2.x, .NET Framework and UWP projects 

Even though C# 8.0 is still months away, planning has begun for C# 8.x. Some of these features are new, while others were previously considered for C# 8. And as always, this list is subject to change. 

explore what's new in C# 8, as well as what we can expect in the near (and far) future of C#!
We'll talk about:
- News in C# 8
- Pattern Matching (incl. Record Types)
- Nullable Reference Types and How to Avoid Null Reference Exceptions
- How Async & Await is Improving

   One of the most popular programming language on the market is getting even better. With every iteration of C# we get more and more features that are meant to make our lives as developers a lot easier. 

C# 7 introduced pattern matching with the extension of the switch statement and the is operator offering the const pattern, the type pattern, and the var pattern. With C# 8 an extension of pattern matching is planned, including the property pattern, the recursive pattern, and a new switch – the switch expression. 

A .NET guideline specifies that an application should never throw a NullReferenceException. However, many applications and libraries do. The NullReferenceException is the most common exception happening. That’s why C# 8 tries to get rid of it. With C# 8, reference types are not null be default. This is a big change, and a great feature. However, what about all the legacy code? Can old libraries be used with C# 8 applications, and can C# 7 applications make use of C# 8 libraries?

This article demonstrates how C# 8 allows mixing old and new assemblies.
