I can't repro this on 3.0.100-preview6-012264 with the following commands:

I also tried the Razor Class Library and Empty templates. @kdcllc can you provide a sample project that reproduces the issue?

[kdcllc]

@anurse I am working on this https://github.com/kdcllc/Bet.AspNetCore/tree/feature/letsencrypt/src/Bet.AspNetCore.Sample project. The latest update is that when I use docker locally without -c Release it builds perfect image but when I use the same docker file in the Azure DevOps pipeline I get the same error.

[mkArtakMSFT]

Thanks for contacting us, @kdcllc.
The action we're going to take here is to make the build failure error message more helpful.

[kdcllc]

@mkArtakMSFT I am still not able to build Docker file inside Azure DevOps pipeline. What is the underline issue here?

[pranavkm]

@kdcllc the issue seems to be the GeneratePackageOnBuild that you have here: https://github.com/kdcllc/Bet.AspNetCore/blob/feature/letsencrypt/build/settings.props#L29. Setting this to false in the sample fixes the issue.

I've filed https://github.com/dotnet/sdk/issues/3365 to track addressing the underlying issue.

[pranavkm]

@mkArtakMSFT using https://github.com/aspnet/AspNetCore/issues/11226 to track further work with the Razor SDK.
