Dear Team,
While running a dot net application on Solum, i am facing an error while the process tries to discover the process types -

Hi Adrian,
I was going through some documents and found this link

http://stackoverflow.com/questions/10810311/nomethoderror-undefined-method-for-nilnilclass
http://mongoid.org/en/mongoid/docs/tips.html

So can it be that the issue which i am facing is because of an older version of ruby, if used for compilation.?
If yes, can we upgrade this and check?

Rohit,

Paul has made some initial progress toward resolving this. We should be able to update you in a day or two with a solution. It may involve forking the Heroku build pack for Mono.

[Paul Czarkowski (paulcz)]

I'm able to build the following app https://github.com/paulczar/dot_net_solum which is your app with an added Procfile.

I've also forked the mono buildpack with a fix to bin/release

this gets the build working, but the container still can't run. I'm not familiar enough with running mono apps ( nor with the buildpack ) to really know where to go next.

[Adrian Otto (aotto)]

Paul,

Thanks for your forward progress on this. Let's reach out to the creators of Mono to give them an opportunity to participate. It might also make sense to track down the author of the Mono build pack. I will send some introductions and see where that takes us.

Thanks,

Adrian

The author of the build pack is apparently employed by Heroku, so he may not have an interest in helping with Solum. I reached out to the Mono developers.

[Paul Czarkowski (paulcz)]

it also might be worth deploying the app to heroku and see if it works
there ... might help work out where the deficiency is.

We will address .Net functionality by allowing users to submit Dockerfile based LPs. We do not plan to support a .Net LP separately.
