C# 8.0 features – an exiting list of new possibilities on the horizon

Posted by jpluimers on 2018/04/04

Shamelessly adapted from [WayBack] C# 8.0 features Extension everything — a new syntax for extension methods that will also allow extension “other things,” like the much-anticipated exte… – Lars Fosdal – Google+, including the original posts where the topics were covered:

C# 8.0 features

Post 1

[WayBack] C# 8.0 Features: A Glimpse of the Future – NDepend: C# 8.0 is on the horizon and will be here before you know it, bringing with it some interesting functionality. Let’s take a peek into the future.

Extension everything — a new syntax for extension methods that will also allow extension “other things,” like the much-anticipated extension properties.

Default implementations on interfaces — this allows you to implement methods on interfaces, giving them a default implementation. That will enable you to add new methods to interfaces without breaking its clients.

Nullable reference types — probably one of the most anticipated features ever. It’s a reinterpretation (a “retcon” for you comic book geeks out there) of all the reference types as nullable and the introduction of a new syntax to denote nullable types, accompanied by several types of static checks, to prevent several classes of errors regarding these types. Say farewell to the null reference exception!

[WayBack] C# 8.0 Features: Another Glimpse of the Future – NDepend This post covers two probable C# 8.0 features: null coalescing assignment and records. It explains what they are and reports on their current statuses, as well.

Null coalescing assignment — a very simple feature to shorten the check for null before assigning to a variable.

Records — this one is pretty interesting. It’s basically a very short way for you to declare classes that are only data holders. The compiler gives you Equals and GetHashCode implementations, a constructor, properties, and immutability for free, allowing you to do something more interesting with your life than writing loads of boilerplate code.

[WayBack] C# 8.0 Features: A Final Glimpse Of The Future – NDepend: Here’s our final post in our C# 8.0 series, where we glimpse into the future. Today we’ll cover another two possible features: target-typed new expressions and covariant return types.

Target-typed “new” expressions — a way for you to omit the type from a constructor call, making the code simpler and less redundant.

Covariant return types — a much-anticipated feature that allows an overriding method to return a more derived type than the original type from the base class.

I really hope they publish the full specs soon, but given that the C# 7 specs yet have to (see [WayBack] C Sharp (programming language) – Wikipedia: Versions), I do not hold my breath, even though it had lots of interesting new stuff too:

From the #AllesIstKaput department: DNS is unusable for many; has government affiliation

Posted by jpluimers on 2018/04/04

Abstract from this morning’s Twitter feed:

  • DNS is broken in many areas (because of for instance AT&T, Vodafone, Cisco screwing up and historically being marked for research purposes)
  • DNS has government affiliation

So what’s left?

  • Cloudflare: alternative to
  • Google: with secondary at

There are a more interesting IPv4 addresses untaken for DNS, but I’m not sure they are likable enough:

And of course there is the reserved (;

Or you could go the way with DNSSEC (and some public ones mentioned in [WayBack] DNS Server mit Persönlichkeitschutz / Blog / Privat – Lutz Donnerhacke):

Zunächst gibt es eine massive Beschränkung von leicht merkbaren IP-Adressen. Der IPv4 Adressraum läßt nur 220 Adressen der Form x.x.x.x zu.


So maybe CloudFlare was an April 1st joke after all: [WayBack] Announcing the fastest, privacy-first consumer DNS service / [WayBack] — the Internet’s Fastest, Privacy-First DNS Resolver

Functional programming in C# – CodeProject

Posted by jpluimers on 2018/04/04

Interesting stuff:

This article discusses functional programming in C# through algebra, numbers, euclidean plane and fractals.
