The .NET Core command-line interface (CLI) allows developers to easily automate and script many tasks in the .NET world. From create new projects in seconds, to automating builds, to setting up better CI with automated testing, and making working with containers possible, this new CLI can almost do it all (especially if you are coming from the full framework world). Join my session to see the .NET Core CLI in action and put it through its paces. This really is a must have tool for any .NET Core developer out there.

The Problem – Tooling is Hard
Projects
Paths, properties,
references for our code
since the 90s.
Solutions
Now throw a bunch of
project files together to
complicate things.
Cross Platform
We want to be able to
build on windows, unix,
mac, mobile, but how.
Legacy Code
Don’t forget the billions
of lines of code already
out there.
Full Framework
Not just .Net Core, but
Standard and Full
Framework as well.

Command Structure
The .Net Core CLI Command Structure consists of

The Driver.
Where the pattern
starts from.
new
The Command.
Also known as
Subcommands,
these are the
“verb”.
-h
The Options.
Not always needed
but these are the
“arguments”.

○Many commands handed
directly to MSBuild
○Others are not (new, sln,
pack)
○ B.Y.O.T
