What's new in C#

The Discussion

• 

  Yeah! C# non-nullable reference types :D

• 

  This nullable reference types feature looks great! I'm excited for C# 8 :)

• 

  I get the feeling that building existing code in C# 8.x with the nullable reference types may not work that well. There are a lot of default constructors out there with reference members. I can see a lot of ?s being typed before code builds.

• 

  Beautiful! C# feels more and more comfortable as it's evolving. Looks like you manage to keep that right balance.

• 

  I would prefer "readonly ref" instead of "in" for method parameters.

  That would be more readable (immediately obvious) and consistent to the return parameters.

• 

  Great!!

• 

  Amazingly described

• 

  Null reference types look great for new projects, however I'm not so sure how well this will play with existing code.

• 

  Thank you so much, I wish all your videos be short and extensive like this, especially Xamarin guys (too much of talk very little of information)

  As mentioned this causes warnings, not errors => you code will build just fine. I do agree however that it's nice if you start with a new project. Even existing projects, even small ones, you probably get 1 billion warnings, making it quite annoying.

• 

  The 'in' keyword for struct method parameters sounds really, really nice.  Unsure if it should be renamed, but hopefully will throw a compiler error for reference types.

  Man, C# is looking better and better every year! I can't wait to see what C# 8.0 is going to bring to the table, especially considering how awesome nullable reference types look. Keep up the good work! 👍

• 

  the nullable reference? really? isn't c# at its core having a reference nullable? guys, wtf?
  stop bringing so much blink blink to c#, it was a beautiful simple language and it's becoming a monster. what happened with keep it simple and stupid? even with a language like that people will build monstrosities, just imagine what they will do with this latest c# which got so much blink blink!

• 

  The Ref's: "We were such idiots that we left pointers out of the language at the beginning.."

  I think I would prefer the implementation of nullable reference to be the reverse where the intent is expressed on the nullable variable. With all these changes, code readability is becoming a concern.
