A MSBuild-integrated library/tool to expose entrypoints in .NET assemblies to the platform invocation system or short PInvoke. It allows you to build .NET libraries that can be called from any development platform that supports PInvoke, including C++, C, Rust, Delphi, Python and so on... 

The team said that “most of their effort to improve the .NET Core Docker experience in the last year has been focused on .NET Core 3.0.” “This is the first release in which we’ve made substantive runtime changes to make CoreCLR much more efficient, honor Docker resource limits better by default, and offer more configuration for you to tweak”.

"The quick brown fox jumps over the lazy dog" is an English-language 
pangram—a phrase that contains all of the letters of the English alphabet. 
It has been used to test typewriters and computer keyboards, and in other 
applications involving all of the letters in the English alphabet. Owing to its 
brevity and coherence, it has become widely known.

In publishing and graphic design, lorem ipsum is a placeholder text commonly used 
to demonstrate the graphic elements of a document or visual presentation. 
By replacing the distraction of meaningful content with filler text of scrambled 
Latin it allows viewers to focus on graphical elements such as font, typography, 
and layout.

Last year a team of six researchers in Portugal from three different universities decided to investigate this question, ultimately releasing a paper titled “Energy Efficiency Across Programming Languages.” 

In the eighteen years that I’ve been doing Web development, a lot has changed. We started out creating HTML pages to present static information to our users. We then used classic ASP to get database data and incorporate that into our pages. To use both of these technologies, we had to know a lot about HTML, CSS, and JavaScript. Along came .NET and we started rendering everything on the server-side. We forgot a lot about HTML, CSS, and JavaScript as Web Forms wrapped up a lot of that for us. Web Forms’ architecture closely mimicked the way developers created desktop applications. This was great for helping developers move to the Web, but unfortunately hid a lot of the power of the Web, and also tended to be a little slow. 

You'll have to migrate to .NET 5 in the near future, and this article will help you prepare for this inevitable migration and avoid the last-minute, unexpected problems that will come up if you procrastinate. 

Kotlin goes WebAssembly!
Kotlin 1.8.20 introduces the newest multiplatform compilation target for Kotlin – WebAssembly! This opens up new possibilities for Kotlin developers, ranging from writing web apps, to blazing fast server-side development with Node.js and standalone WebAssembly runtimes, and even bringing your Compose Multiplatform apps to the browser! 

This lets you do things that you can’t do in WebAPI’s default binder, specifically:

1. ModelBinds everything, including the body. Assumes the body is FormUrl encoded
2. This means you can do MVC scenarios where a complex type is bound with one field from the query string and one field from the form data in the body.
3. Allows multiple parameters to be bound from the body. 

The C# Language Specification is the definitive source for C# syntax and usage. This specification contains detailed information about all aspects of the language, including many points that the documentation for Visual C# doesn't cover.
