Hi, this is a video tutorial to get
started with Visual Studio code
on your Mac with .NET Core, wait,
something doesn't feel right.
Much better.
First, go to your favorite search
engine and type in Visual Studio
code, one of the first results
will be code.visualstudio.com, and
it'll bring you automatically
to the Mac download.
And this installs really quickly,
because Visual Studio code is
a lightweight source code editor,
it's much different from Visual
Studio, which is the fully featured,
integrated development environment,
but with .NET Core and
the C Sharp extension,
VS code can do some really cool
debugging stuff with C Sharp.
All you need to do is go over to
the Extensions tab on the left,
click it and
install the C Sharp extension,
it'll be one of
the first suggestions.
Now that you have Visual Studio
code, you need .NET Core to compile
your C Sharp, so go back to your
browser and type in .NET Core,
one of the first results will
be Microsoft.com/net/core.
To install it on a Mac, the easiest
way is by using HomeBrew,
if you don't have it installed,
it's very easy to get, just copy and
paste the HomeBrew install command
from their main website into your
terminal.
And I'm going to be speeding
up these installs slightly,
because I wanna give a tour,
and not waste anyone's time.
Now I can run brew update and
brew install openssl,
because we'll also need openssl, and
I'll run the next few commands here,
which make a directory and
make your symbolic links.
Next click Download .NET Core SDK,
go ahead and
click on that download and click
through the .NET Core installer.
Once the install is complete, I'll
take you through the next commands
on our install page, which create
a basic .NET Core console app,
I'll speed this up a little bit.
There we go, so I'll navigate to my
Documents folder at the terminal.
And type dotnet new console -o
hwapp to initialize my project.
Here I'm using the -o to specify
the output directory as hwapp,
the hw standing for hello, world.
Now I can use the dotnet commands
to run dotnet restore and
dotnet run from the command line,
dotnet restore restores my project
dependencies using NuGet.
Now let's open Visual Studio codes
so we can edit and debug our
C Sharp, go to the file tab on
the left and click Open Folder,
I'll open the hwapp folder that I
just created from the command line.
As you can see, I have a csproj
loaded here next to my program .CS
file, pop ups will appear asking you
to yes load the build assets and
restore your project.
Now, let's debug our app,
click on the Debug tab on the left,
it's the one with a little bug
with a line crossing it out.
Now, you can hit the green debug
arrow at the top left of the Debug
tab, you can also drop a break point
and hit Debug again, and you can see
the local variables loaded on
the left, you can also check those
variables in the Debug console by
typing them, and there's args.
Now I'll hit continue
to complete debugging,
so that's your first .NET
Core app running on your Mac.
Thanks for watching.

    I'm experiencing issue with dotnet build in vscode on a mac via launch.json. The build actually is configure to output a file as well (comments in .xml) via csproj. During the build via vscode terminal it complains about not having the correct permissions. The only way I can get it to work is via sudo dotnet build. Is there a way to configure vscode to launch the app (build then launch) with admin rights? Or do you have to just open the app always with elevated permissions?

    @Derek:Sounds like you are initializing a project inside a folder that can be used by the admin only. Unless that is intentional I'd do my dev work in a folder that isn't admin access only if it's getting in the way of your workflow. Or you could change the permissions on that folder.
