Announcing Preview 1 of ASP.NET MVC 5.2.4, Web API 5.2.4, and Web Pages 3.2.4 

This release contains some minor bug fixes and a couple of new features specifically targeted at enabling .NET Standard support for the ASP.NET Web API Client.  

JavaScript Object Notation (JSON) is a subset of the JavaScript language used for the definition and exchange of data. While I’m not proposing that we create a similar standard using C#, I do want to illustrate some of the rich object initialization syntax of the language.

This project intends to provide a complete description and re-implementation of the WhatsApp Web API, which will eventually lead to a custom client. WhatsApp Web internally works using WebSockets; this project does as well.

Microbenchmark testing Python, Numba, Mojo, Dart, C/gcc, Rust, Go, JavaScript, C#, Java, Kotlin, Pascal, Ruby, Haskell performance in Mandelbrot set generation 

Benchmarking several languages/tools with Mandelbrot set generation. 1-to-1 translation of code from one language to another. No SIMD, no multithreading (except prange() trick with Numba), no tricks (e.g. skipping sqrt), a bare minimum of language specific adjustments to make the code nicer while keeping all loops and operations in place. 

Modern is a header-only library designed to provide Standard C++ developers with first-class access to the modern Windows API.
