Been using .Net Core for a few weeks now. It's my new favorite platform, over node, java spring, or anything on Python.
The dotnet cli command line tools are amazing. It's also very fast. .Net Core is actually a continuation of the .Net Native project, so many things in .Net Core compile to native machine code (self contained framework with no reliance on an external dotnet framework).
You can add new commands to dotnet as well. For example Entity Framework 7 moved away from the PowerShell commands "Add-Migrations" and now it's
"dotnet ef migrations add MigrationNameHere"
or
"dotnet ef database update"
Also the MVC 6 TagHelpers are pretty awesome too in ASP.Net Core.
For example, you can use the new <environment names="Development"> tag to have different html output for different environments. So you use that to determine whether to use your minimized JS files and source maps, or all the non minimized files for development, etc.
