Cannot push, compile errors

[yngndrw]

I've tried this using the latest Katana sample but keep getting compile errors:
https://github.com/friism/KatanaTest

Steps:

1. Downloaded KatanaTest as a Zip and unpacked

2. Git Initialised and committed all files

3. heroku create --buildpack http://github.com/friism/heroku-buildpack-mono.git

4. git push heroku master

Could this be cause by the version of Mono not being compatible with the latest Owin libraries ? I tried with Mono 2.8 which didn't work and Mono 4.0 worked (On my local machine) - I couldn't find Mono 3.1 to try locally.

[friism]

It could be because the mono that I compile doesn't have required components: https://github.com/friism/mono-builder

I'm not really working on this buildpack anymore - I've spent some time on the new ASP.NET stuff, although I haven't touched that recently either: https://github.com/heroku/dotnet-buildpack

[yngndrw]

Thanks for your reponse Michael.

ASP.Net 5 / vNext is something which I've been meaning to investigate for a while, but it's good to know that there's a buildpack that's ready and waiting for it. Sadly it's still using Mono 3.10 so for my immediate problem it doesn't resolve it, however.

I think I'll have to fork this project and give Mono 4 a go. I don't have an S3 bucket available so I'll probably modify it to download the binaries from GitHub while I'm at it. Will update this issue with the results.

[friism]

Sounds good, check this out: https://github.com/SuaveIO/mono-script-buildpack/blob/master/bin/compile

This is how they build: https://github.com/SuaveIO/mono-builder

[yngndrw]

Sadly using Mono v4.0.1 didn't help, looks like Nuget.exe is now failing to run under Mono. I'm a little out of my depth as I don't have much experience with Mono - Can you offer any suggestions on this issue ?

I don't know what could be causing this - again, I recommend working on the ASP.NET 5 stuff instead.

[yngndrw]

I seem to be getting the same issue with your ASP.Net 5 buildpack. I made my sample using the Visual Studio 2015 RC new web project template:

It's possible to work around nuget problem if you include packages folder in your repository and push it with sources.
