Hello -- it looks like the C# tools we use to build Avro will fail to install in the docker image until https://github.com/dotnet/core/issues/3988 is fixed. Looking through their issues, it looks like this happens occasionally and is usually fixed rapidly by the Microsoft team, so the problem should just "go away" if we wait long enough.
I'm not sure what we can do to avoid this, but it seems like an argument against using a single docker image with all build tools. Any other ideas? In the meantime, it looks like all commits to master or PRs will fail. Ryan
