ASP.NET vNext on Mono, install new runtime version

I trying to run asp.net vnext demo apps from here https://github.com/aspnet/Home, ConsoleApp working fine, but HelloWeb throws System.IO.FileNotFoundException exception when I trying to launch kestrel.

I have following environment:

  • OS Debian
  • Mono version 3.12.0
  • Vnext runtime version - 1.0.0-beta4-11169

I think problem in version mismatch. I have runtime version beta4 and project.json file, that refers on beta3 assemblies.

So, I need to install runtime version beta3. In general I understand that first of all I must install runtime beta 3 version with kvm install command, and then switch to beta 3 with kvm use command.

But this is in general, can you give more detailed description of how to install new version runtime with examples of correct commands?

When you get a FileNotFoundException, it might be a good idea to post the message saying what file it was that couldn't be found. - mason

As far as I'm aware ASP.NET 5 (vNext) runs on .NET Core, which itself is cross-platform. You only need full .NET if there's a framework feature you need that Core doesn't provide (which shouldn't be the case for a typical web application). That means you shouldn't need Mono, at all. - Chris Pratt
try those command : export KRE_FEED=https://www.nuget.org/api/v2 then kvm upgrade - agua from mars
From the aspnet github pages: "NOTE: There is no Core CLR currently available on OSX/Linux. There is only a single platform (mono45) and a single architecture (x86)." - Gabriel Garcia

Do not mix versions between betas as this causes problems. Also upgrade to the latest version which is Beta 7 at the time of writing. Follow the official announcement instructions on how to upgrade.
