Visual Studio is as objectively as possible not a bad IDE. If you have unlimited budget and are only doing C# and DotNet, only benefit of VS Code is start up performance. Of course for just about anything else VS Code is as good as Visual Studio.

Can't speak to how prod ready this is, would never use a major upgrade like this in production within the first 6 months of it's release. Bless those who have the way but that's madness to me.

the highlights are great. 2 lowlights: - HttpClient/WebRequest ReadWriteTimeout is silently ignored which can result in infinitely hung sockets when doing synchronous network i/o - System.Speech is unsupported

The ReadWriteTimeout issue was insanely aggravating; MS was adamant it was not a bug but rather an internal implementation detail for the longest time. I'm really glad they changed their minds because it was a very unexpectedly petty stance they were taking in the GitHub issue.

I know .NET Core applications could run on Linux. But do they natively (without any wrappers) support Linux OR is there a wrapper to simulate windows within Linux?

No thanks. I've been writing .Net since before day one and quite frankly I've been buggered around enough now to run as far away from this as possible.

Interesting, I always felt C# was a step ahead of Java, while the JVM was some steps ahead of the CLR.

The language is absolutely brilliant and I love it. It's the vendor's schizophrenia that's the problem. I've run out of fingers to count things that have been deprecated painfully on after being promoted as the next greatest thing and sold hard. This has cost me, my clients and my employers ridiculous amounts of money to unfuck.

what makes you say they changed their mind? afaik it's same old story. it's really incomprehensible given that all they need to do is make a call on the underlying socket.

It supports linux natively. Anything windows-specific requires libraries that you can optionally add.

As someone who uses .NET daily, but loves Clojure and other functional programming paradigms - Records seem like a very compelling feature. Immutable data structures without any hassle to set up. Simply write “record” where you would normally write “class” and boom, you are working with immutable objects. This is one step closer to one the best features of Clojure IMO -everything is immutable.

Additionally, there seems to be another new way to accomplish this. Normally class properties are accessed via get; and set;

Now we have the ability to use get; and init; which effectively makes the object immutable/read only after initialization. The syntax is just a little cleaner and more obvious to the reader how the property should be used.

C# has really been adding some great features the past few years and is certainly getting more expressive and concise which I appreciate.

With Linux support AOT compliation and other goodies I wonder how many people will prefer writing backends in .NET over Java.

I think that Java ecosystem is more diverse. There are multiple JDK implementations. There are a lot of OpenJDK builds from different vendors, including paid support options. There is an extremely mature library and tooling ecosystem. While I don't think that JVM is superior to .NET VM, it's not inferior either. .NET supports value types while JVM support some very advanced garbage collectors. And, of course, JVM development is not over. Hopefully, in a few years there will be value types in JVM as well. Java is inferior to C# as a language, but there's Scala or Kotlin for those who want better language and they are more on-par with C#. And for many people Java language is enough to write good code and they don't really need any more features. May be simple language is a feature in itself.

I don't see any strong reasons to switch to .NET from Java for those who heavily invested in Java already. But I think that .NET is pretty strong, so the same argument could be made for the other direction, for folks who are fluent in MS infrastructure and want to tackle Linux, .NET probably is good enough to keep using it.
