referencesource VS CoreFX

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.

The whole .net framework source code is online.

.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!

Maybe from the source of FtpWebRequest it is possible to track what the default behaviour is.

The class is just a very limited dictionary, a library will be the same or better.

System.Buffers v4.0.3.0 / v4.6.28619.01 @BuiltBy: dlab14-DDVSOWINAGE069 @Branch: release/2.1 @SrcCode: https://github.com/dotnet/corefx/tree/7601f4f6225089ffb291dc7d58293c7bbf5c5d4f / v4.6.28619.01

You’re right. Thanks for correcting me. The logic of applying the predicate for the two are inversions of each other, and they are even implemented in the same file: AnyAll.cs.

- EF Core is not MSSQL first. EF Core is an abstraction layer and is in no way tied to Sql Server. In fact, Microsoft's own getting started tutorial uses Sqlite (1). I've personally used the Postgres drivers in production and they are as good/production-ready as Microsoft's SQL library for EF Core.

- "Many libraries ship with two implementations..." I've yet to come across these "many" libraries in the 5 years since I've been building services with .NET Core.

"The community is really culty" - I'm not sure where this is coming from. It's hard to refute such vague criticisms.

- "It's practically open source in name only" - Here is the base class library source: https://github.com/dotnet/corefx/releases

Dotnet foundation publishes their C# coding style along with an editorconfig and some tooling to support it.

I created the bug report on GitHub. After that, the .NET development team fixed some code fragments described in the article. Among them - the errors with interpolated strings. The corresponding pull request.
