- Cannot interop with other languages/VMs that do async differently. The nice thing about promise-based async is that it's very easy to map to straight C ABI callbacks, which means that it can be fully cross-language. Green threads are runtime-specific.

"Cannot" seems a bit harsh. CompletableFuture isn't going away, and is made for callback situations. With green threads being "free" (you can have millions), it might be reasonable to just block your green thread until the callback arrives.

It also means that the first major vulnerability in .NET Core will be an unmitigated clusterfuck, as admins will have no automated tooling in place to update .NET Core with security patches. "Just recompile with the new version!" I hear the cries already, said by people that have never had to support literally a thousand applications in a government data centre, half of which were built years ago by a vendor that is…

Publish your apps without .net core (--no-self-contained) and install/manage runtimes as you usually would. If you have thousand apps, you probably also have a CI/CD system and you can gain fine grained control on your runtime management needs with .net build/publish. MS does quite a few things poorly but they have done a solid job of operating in large enterprises.

> you probably also have a CI/CD system

Or more realistically, dozens of CI/CD systems, covering less than a third of the applications.

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 see…

Aren’t records pretty trivial to create as a custom class in C#?

If you want to see how much code you get 'for free' by defining a record that you used to have to do manually, check out the generated C# here (structural equality, GetHashCode, Deconstruct, cloning for 'with', pretty printing, etc)

I wish the post was more direct that .NET 5 is the successor to .NET Core 4. I gathered this was the case but it didn't feel clear that I don't need '.NET Core' anymore to run .NET on mac/linux.

There is no .NET Core 4? There was a .NET Framework 4. 5 is how the streams are being crossed.

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

System.Speech has sadly not been supported since the beginning of .NET (as in dotnet, not the framework)

That pretty much means MS is deprecating it in favor of the Azure speech services...yeah, bummer.

So, on the plus side with the new .net, I recently made a .net core web app on Linux, and generally it's been pretty easy. I'm also impressed at just how fast asp.net core is compared to asp.net, the time it takes to open your site in debug mode has dropped dramatically, from what used to be 1/2 minute in asp.net to a few seconds in .net core. On the bad side? Mainly the asp.net core team and their push for Dependenc…

I'm so glad I'm not alone. I adore C# and the .NET runtime is so convenient. But the ASP.NET part feels bloated. Is there a simpler .NET framework?

>Microsoft won't commit to maintaining any cross-platform GUI libraries. Isn't that MAUI?

MAUI is relying on the community to provide Linux support, just like with Xamarin.Forms. I worked with Xamarin.Forms, it doesn't support hardware acceleration in its GTK backend, making it unusable on HiDPI displays (consumes too much CPU). Why would MAUI be any different?

> Why would MAUI be any different?

Speaking cynically, if it's tied enough into the main Microsoft Ecosystem it will have more community buy-in.

You see this happen with other parts of .NET as well, often to the chagrin of the OSS Devs who filled Microsoft's gaps only to be replaced by an (often inferior) solution.

The future is very bright for .NET. It has the right raison d'etre - .NET is part of the growth story for Nadella-Microsoft.

They already have you programming in their editors (VS/Code) and pushing to their VCS (Github). They're even teaching you the C# type system with TypeScript :) If they can just convince you to use their stack, Azure will win you over from AWS every time.

As a result, I really wanted to adopt .NET earlier this year. But they have some work to do to make the ecosystem approachable to newcomers.

One of the core issues feels so... trite. But experiencing it, I realized how real it really was:

The Names. Microsoft has created a Ninja Warrior obstacle course of proper nouns.

It is comical. It is worthy of parody.

.NET, the CLR, and their relation to C# and F#. ASP.NET, ASP.NET MVC, ASP.NET Web Api, Blazor vs Razor, .NET Core vs .NET Framework vs .NET Standard.

I think I could draw the lines between all those with about 50% accuracy. And I read like 3 books on .NET before diving in.

It's bad off the top when you're trying to figure out which way is up in the ecosystem. It goes from bad to worse when you're looking through docs and Stack Overflow answers.

It was almost never immediately clear if a document I was looking at on Microsoft's own website applied to me or not. That is a cardinal sin of technical documentation.

Ultimately, this meant that .NET Core Web API (or whatever I was using) felt poorly documented.

I'd find myself looking at docs that mention .NET Web API - but I can't remember if that rolls up to .NET Core or Framework -- or both? Am I using MVC? Is Web API a subset of MVC? No clue.

It's definitely a hard problem. Here's to hoping that now that everything is unified, they can work on paving clearer roads into their ecosystem.

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.

F# programmer here. I still find VS superior to anything on VS Code, and a lot of people prefer the VS Code Ionide F# IDE.

Most importantly I could do everything in F# I need to do (or can do in VS), debugging, refactoring, interactive tests, on the free Community Edition of VS. It just happens I use Professional because my company pays for the license.
