Linux, Kestrel/libuv related: System.DllNotFoundException: WS2_32.dll

See original GitHub issue

Steps to reproduce

Try to run existing net451 MVC application with RTM bits on Linux. The RC2 bits worked fine on same machine. Application runs fine on Windows 7 and 10 with RTM bits. This is probably related to: https://github.com/aspnet/KestrelHttpServer/issues/730

Expected behavior

Application runs normally.

Actual behavior

Unhandled Exception:
System.AggregateException: One or more errors occurred. ---> System.DllNotFoundException: WS2_32.dll

It seems that this issue has been resolved with @pompomJuice’s workarounds. Will close. If the issue still reproes, please reopen on aspnet/Kestrel.

Kestrel had some serious issues running on linux/dotnet core rc2/mono/net451. Release 1.0.0 fixed everything (wow!), but it still does not run out of the box. The required steps to make aspnet core run on ubuntu linux net451 are:

Install Mono 4.4
Install latest CLI debs found here
Install libuv found here
Install System Native using this
Apply hacks described here (workaround for cli not being able to extract environment variables on mono/net451)

Boom, it works! @nmilosev linkz
