Skipping unpublishable project.

I get below feedback in the build step log when I try to build a deploy package using .NET Core (dotnet). It is a VS 2017 solution. This is the first time I am using TeamCity, and I am not certain, that I'm on the right track at all - When trying to use MSBuild, the Agent states it is incompatible.

Can you guys send me in any direction for further trouble shooting?
