Thanks for the report @mjnorman.

Are you pushing a published app, or just source code? Can you provide a stripped-down version of the app that demonstrates the staging failure?

[mjnorman]

This was with a published project. Oddly enough if I push from the main project directory without doing a publish, I don't receive any errors and the app runs.

I was able to recreate via "dotnet new webapi", add reference to Microsoft.AspNetCore.All with no version reference.

Package pushed with

dotnet publish -c Release
cd/to/dir
cf push Repro -b https://github.com/cloudfoundry/dotnet-core-buildpack.git

Leads to the same AspNetCore.All errors mentioned above. Repro can be found here, https://github.com/mjnorman/DotNetCoreAllRepro

@mjnorman The current latest dotnet core buildpack does not contain the 2.1.1 dotnet runtime. We will release a new buildpack with that dependency soon. In the meantime, pushing the app un-published should work. You could also try publishing as a self contained app.

[mjnorman]

Ok I see the issue now. Since I am running this from a concourse pipeline, and issuing the publish from the latest microsoft/dotnet docker image (which has 2.1.1), it is expecting it to be there when the buildpack runs. Thanks for the help!
