Create New Minimal Start From Scratch CoreClr

How to create new minimal start from scratch CoreClr?

[mattwarren]

Why, for what reason? Is there something missing from the existing CoreCLR?

Is this because you want to go into production with a replacement CoreCLR? As a learning exercise? Or something else?

If you want to learn about creating a minimal .NET runtime you should take a look at a write-up I did on DotNetAnywhere, it's not fully compatible with .NET, has some missing functionality, but it's certainly minimal and the code is easy to follow. Also this talk by the author of DotNetAnywhere is pretty interesting So you want to create your own .NET runtime?

I tried DotNetAnywhere. I built it but it cannnot run demo game. It has good structure though.

Yeah, it's far from production ready and it's no longer maintained, so that won't change.

But, it is a really useful learning resource and it was the .NET runtime for the initial version of Blazor, so it's served it's purpose!
