Unable to load libuv in windows server 2012 r2? - asp.net-core

Question

In visual studio code, I issue dnx kestrel in command line palette.
But I am encountering an error like this

profile is available. Using 'C:\Users\myaccount\AppData\Local\ASP.NET\DataProt
ection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.

How do I fix this?
Thanks.

Answer 1

Kestrel use libuv an asynchronous I/O library. So, you could install it to use Kestrel as web server, or you could use dnx web to launch your app, where web is a command in project.json.
"commands": {
"kestrel": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.Kestrel --config hosting.ini",
"web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --config hosting.ini"}

Why do you want to use kestrel on win2012 ? You'd better use IIS or AspNet selfhost instead. Kestrel should be use on Linux or Mac
Oh so there's a thing called self-hosting? thanks #agua from mars for that info
