CoreFX VS Roslyn

https://github.com/dotnet/corefx/pull/28278

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.

Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

At runtime, the Case C# expressions are embedded into a function and dynamically compiled into an assembly using the Roslyn C# compiler. Then the function that contains the expression is called (e.g. CaseAvailableFunction.Availablle()). At runtime, the function provides various methods to access stored case values as well as the current input data.

I like to use the roslyn coding practices for C# projects (https://github.com/dotnet/roslyn/blob/main/docs/wiki/Contributing-Code.md)
