- Discriminated Unions: Essa feature faz falta no CSharp

DevDocs
Certain parts of Microsoft Learn are permissive, for example the .NET BCL documentation is Creative Commons Attribution: https://github.com/dotnet/dotnet-api-docs as is ASP.NET Core: https://github.com/dotnet/AspNetCore.Docs (a good hint if documentation is permissively licensed and on GitHub is if there's an edit button at the top.)
The C# language specification is unfortunately a bit fuzzier: https://github.com/dotnet/csharplang/discussions/4855
The updated unified C# language specification is CC, but it's still catching up to modern C#: https://github.com/dotnet/csharpstandard

The golden age of Kotlin and its uncertain future
No OP, but for example you still see the C# folks still struggling to add discriminated unions to the language because of complex interactions due to its too many features[1]. Virtual threads are easier to use than async/await is another example.

When static types make your code shorter
For example, C# had a research fork called Spec# that had compile-time support for contracts, with keywords such as requires (for arguments) and ensures (for return values), all the way back in 2004. While still being discussed, it doesn't seem to be shipping any time soon.

.NET 8 – .NET Blog
Hi there. I'm the language designer who created the 'Collection Expression' design/specification: https://github.com/dotnet/csharplang/issues/5354
You can see the entire history of the proposal there. To answer you specific question, we went with `..` because that's what the language already uses for the complimentary 'pattern matching deconstruction' form for collection patterns.
In other words, you can already say this today:
if (x is [var start, .. var middle, .. var end]) { ... }

What's new in C# 12: overview
You must specify concrete type.
There was a plan to have "natural type" so "var list = [1,2,3]" would be of type "List" but it was postponed to C# 13 (https://github.com/dotnet/csharplang/issues/5354#issuecommen...)

Robust Design through Value Objects in C#
While C# currently lacks direct support for this kind of functionality, there's a glimmer of hope with an active proposal under discussion that aims to bring this feature to the language. This potential addition promises a future where C# can natively offer similar robust type narrowing.
-
The combined power of F# and C#
Given few people anticipated ValueTuple and C# adding a more direct tuple syntax, I feel like it is only a matter of time before C# adds discriminated unions.
(There are multiple proposals tracking the idea. This seems the most comprehensive and "central": https://github.com/dotnet/csharplang/issues/7016)

Should i quit Django and move to asp.net
I always liked list abbreviations in python, but I absolutely love Linq. I believe there is a feature proposal for C# 12, which makes collection initialization better imo.
- Can constructor parameter assignment be made less verbose?

I wanted to make a quick video about the differences between classes and structs in C#. It turned into a much deeper exploration where I learned a handful of things I definitely didn't expect. I hope it is useful to other people!
(Source: I needed to hack a detection for this for my expression-tree-to-csharp decompiler, here: https://github.com/EamonNerbonne/ExpressionToCode/pull/196)
