A Tour of Scala VS referencesource

Martin Odersky is just a very nice guy and I get the impression that he isn't keen on saying "no", which is how you end up with a language that allows you to use xml tags inline (no longer supported in Scala 3),

https://github.com/scala/scala-xml/wiki/Getting-started

The "opinionated" Scala are the Typelevel and Zio stacks, which are very cool.

The problem with the "better Java" approach is that although it has helped Scala's growth a lot, it has also made it susceptible to Kotlin. The Scala code that doesn't use the advanced type magic can be straightforwardly rewritten in Kotlin instead. Kotlin also stops your bored developers from building neat type abstractions that no one else understands.

People who use Scala only has a "better Java" can now use Kotlin has a "better "better Java"".

https://github.com/scala/scala-xml/releases is now published separately from the main language.

Take a look at the ValueType.Equals(Object? obj) implementation by Microsoft.

Compared to any major UI library out there. Take QT for example:

https://github.com/qt/qtbase/blob/5d1ded3359ee8bffa33a4b83d5...

That ANT Table is not complex. QT has tons of legacy and supports way more features, yet, code is easier to grasp and maintain. Also, C# and WinForms, if you don't like C++:

But to go deeper to .NET/CLR architecture is important too. Try to understand how it works inside. Use the source, Luke! https://source.dot.net/ https://referencesource.microsoft.com/ This source code vaults is not completed then try JetBrains dotPeek tool to look at any assembly source code.

(https://github.com/Microsoft/referencesource/blob/master/System.ServiceModel/System/ServiceModel/MessageSecurityVersion.cs; scroll down to inner classes)

List is an IList/IReadOnlyList; these interfaces do nothing that couldn't be done right inside the file itself.

Instead we have to go diving through the IList, which implements ICollection, which implements IEnumerable, which implements IEnumerable (again). Just because each interface is composed of another interface, doesn't mean you aren't using inheritance. You are effectively creating a custom inheritance tree through willy-nilly composition.

It is gratuitous to make this chain so deep, when the underlying code is just a handful of lines.

The doc-strings are unnecessary. It's self-evident what most of the code does if you read it.

        // Returns an enumerator for this list with the given

The whole .net framework source code is online.

https://github.com/microsoft/referencesource/blob/master/System.Numerics/System/Numerics/Vector2.cs https://github.com/microsoft/referencesource/blob/master/System.Numerics/System/Numerics/Vector2_Intrinsics.cs

.net itself has arbitrary interfaces, ex https://github.com/microsoft/referencesource/blob/master/mscorlib/system/action.cs

Assuming if you are new to C# - start coding! And start reading https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csha...

If you are not new to C#, start building an application end-to-end/a classic n-tier application, right from using a database, Entity Framework, WebAPI, DTO, AutoMapper, and a front-end (your choice - Angular/React/Vue with TypeScript or better yet - Blazor).

You will not only understand & use dependency injection, reflection, LINQ, multi-threaded programming, generic programming, source-code generation, unit-testing - and much much more in a practical/real-world usage.

Peruse https://referencesource.microsoft.com/ once in a while.

Follow various team members of .NET Framework, C# team and the like on various social-media. https://mobile.twitter.com/i/lists/120961876

I am sure there will be who agree / disagree with the above approach and will provide more viewpoints for you to consider.

Enjoy - and strap yourself for an amazing journey or roller-coaster ride, however you want to call it!
