68 things the CLR does before executing a single line of your code

The article could benefit by having a single sentence explaining what CLR is:

"The Common Language Runtime (CLR), the virtual machine component of Microsoft's .NET framework, manages the execution of .NET programs [that runs primarily on Microsoft Windows].

-- https://en.wikipedia.org/wiki/Common_Language_Runtime

good point, I'll update the post (although I think that most people who read my blog are .NET devs)

Matt Warren's blog is great to learn about the internal mechanism of .Net. I wonder if there is any similar blog for JVM world, so far I have only know Mechanical Sympathy[1] but it doesn't seem as comprehensive.

not a blog, but it might be just what you are looking for:

https://www.amazon.com/Inside-Java-2-Virtual-Machine/dp/0074...

https://www.amazon.com/Virtual-Machine-Masters-Venners-1997-...

Cool, thanks for the links, they look like interesting books (even for a .NET dev)

Yeah I do seem to write alot about .NET internals, but I just seem to keep finding cool stuff in there!!

Another Java-based blog I like reading is http://psy-lob-saw.blogspot.co.uk/, I've definitely taken some inspiration from there and written .NET equivalents of his posts.

The title could be read to mean that 68 things are done before every line of code is executed. Got me to read it.

That was exactly what I thought as well... I was wondering how it could be performant

yeah you're right, I guess you can read it like that, I never noticed that before

(I was just so please that I managed to get a 'BuzzFeed' style headline into one of my blog posts!!)

Nice read, makes it a lot easier to understand how it works and a must read for people who want to contribute to CoreClr!

Thanks, yeah that's the aim of writing posts like this (plus I find it fun to figure it all out!)

Is there a way to embed multiple, independent DLLs into one host application with the possibility to reload/unload DLLs in .NET Core? I didn't find a way yet because .NET Core does not seem to support the AppDomain concept.
