dnvm install Mono

I've trying to build a Docker image that installs mono and runs a .NET app.

I'm basically following the standard guidelines on how to build a Docker image for ASP .NET 5, but want to use Mono as the native host instead (so I can leverage non-CoreCLR dlls).

However, out of the gate, this fails:

D:\>dnvm install mono410

As you can see I tried two different versions of Mono, so I don't think it's version specific...

What am I doing wrong?

UPDATE:

Solution

mono410 is not an accepted value for install. What are you trying to do?

Also, make sure you have mono installed because the command above only brings dnx for Mono, not Mono itself.

However, because you are running on Windows, it is not possible to install the mono runtime using dnvm. We already have an item tracking this and the PR is out for review. It will probably be merged very soon.
