Earlier quoted context omitted.

Hopefully these optimizations are for a particular version of .NET Standard and will see themselves in both .NET Framework and .NET Core.

Skimming, but it doesn't look like these optimizations are relevant to .NET standard (which is a formal specification of a set of APIs - not a particular implementation.)

Correct. Performance improvements are out of the scope of the standard. Much like how the HTML spec doesn't tell Google and Microsoft how fast their browsers need to work.

This is such a good point.

We (TechEmpower) had this in mind when we created our framework benchmarks project a few years back. Performance improvements in platforms and frameworks have the potential of very broad impact. With our project, we wanted to provide some inspiration for doing that kind of performance tuning. We had found ourselves in many conversations about how many real-world CRUD web applications take multiple seconds to render a page with a form. We realized that if, just as an example, the JSON serializer or template engine were substantially faster, many real-world applications that use those components would see notable improvements to their user experience.

I hope most or all these will find their way into the full framework. It's a bit odd that this is so rarely mentioned. I still haven't quite grasped the relation between core and the full framework when it comes to fixes like this being merged into the full framework.

As .net core is a full rewrite, all these optimizations are .net core specific, so porting them isn't going to be a easy thing.

.NET Core is not a rewrite in any way. It's the same runtime with the same GC and JIT, same language compilers and mostly the same standard library. It has just been stripped down by removing deprecated features (such as code sandboxing / partial trust) and made support non-Windows platforms.

You might have confused it with ASP.NET Core, the web development framework, which is a full rewrite.

Every time I try to get a quick feel of .NET on Linux, I allocate an hour to it and that hour is always spent wandering around various guides on microsoft.com and never getting anything done.

There are terms like .NET Core, .NET Platform, .NET Framework, .NET SDK all mixed up on nearly every page, multiple versions of "Getting started" and "Quick start" guides, massive navigation menus and options on every page so you never know if you're looking at the latest and greatest or it's some kind of abandoned dark corner of a web property, as it often happens with corporate sites.

Yo! If you want .NET to be a massive hit on non-Windows platforms, move it off Microsoft.com to a small site, have a single version of "getting started" (and only one "guide"). Don't ever mention things that exist and don't work on Linux.

Like this: https://golang.org/doc/

Also, have a simple downloadable .tar.gz which expands into /bin + /lib + /examples. I loved C# back in my Windows days and I moved to Linux to escape Microsoft complexities and over-reliance on complex IDEs and tools, scattered like shrapnel all over my c:/

I will not run apt-get against your repo without knowing ahead of time what I'm getting and where will it all go, so let me play with the tarball first.

Always interesting timing by technology companies. Here's a post to developers by Microsoft the day AFTER Apple's State of the Union presentation to developers.

Microsoft touting performance improvements the day after Apple amps up performance on pretty much every aspect of the Apple developers infrastructure (Xcode, Swift, APIs, processor and GPU utilization, etc).

Must be a coincidence...

Yeah, the Microsoft docs are all always a pain to navigate. A lot of seemingly duplicate content. Not that Apple's docs were any better for many years (Swift docs are much better).

In contrast to those two, I've found Android's pretty good in the 3 years I've been referencing them.

Point taken. We have some improvements to make on this front.

I liked the original modern.ie site. It was so much easier to navigate than modern microsoft sites.
