pkgsrc/lang/mono and network access

[Ryo ONODERA <ryo%tetera.org@localhost>]

Hi,

I have installed lang/mono-6.12.0.122 and compiled simple network access
program written in C#.

It is based on:
https://gist.github.com/bryanbarnard/8102915/

However compiled SimpleHttpClient.exe cannot resolve FQDN
with DNS.
If IP address is used, HTTP GET cannot get any date.

Anyone has the same problem? Or lang/mono can access network for you?

The error message is as follows:
GET: + http://deuterium.ryoon.net/~ryoon/dell-xps-13-9300/ihidev/linux-lspci.txt
