5. Agenda
1. Evolution
and
why
open-­‐source
matters
2. Getting
up
and
running
3. Going
live

6. How
did
ASP.NET the
web
evolve?

8. This
used
to
be
simple!

9. Challenge
– Frontend

10. Challenge
– The
Server

11. Diversification

12. Our
story
– InvoiceXpress Architecture
+
Dev
Culture

13. Collaboration
(Microservices +
Devops)

14. Containers!!

15. So,
what’s
ASP.NET
open-­‐source?

16. 64-­‐bit
JIT
+
SIMD
Garbage
Collector
Runtime
components Compilers
.NET
Compiler
Platform
(Roslyn)
Languages
innovation
.NET Framework 4.6 .NET Core 5
Fully-­‐featured
and
integrated
.NET
libraries
and
runtime
for
Windows
Modular
and
optimized
.NET
libraries
and
runtimes
Base
class
libraries
NuGet
packages
Libraries
.NET
on
Linux
and
OS
X

17. .NET
Core
+
CoreCLR
• .NET
Core:
• CoreFX (libraries)
+
CoreCLR (small,
optimized
runtime)
• Cross
platform:
Windows,
Linux,
Mac
• Side
by
side
installation,
no
shared
code
• Modular,
use
only
what
you
need
• Xcopy deployments
• CoreCLR:
• Runtime
implementation
for
.NET
Core
• Includes
RyuJIT,
.NET
GC,
native
interop,
etc…
• Everything
is
open-­‐source
on
GitHub
• EntityFramework 7
is
supported

18. Building
ASP.NET
on
a
Mac

19. Getting
up
and
running
https://github.com/aspnet/Home
• .NET
Core
already
installed
as
part
of
VS2015
RC
• Clone
repo
on
GitHub
and
build
from
source
(advanced)
• Download
installer
• Use
Homebrew
formula
on
GitHub
• Manual
install
• Download
&
install
tar
file
• Create
VM
on
Azure
Marketplace
• Use
Dockerfile
on
Docker Hub

20. Editors
and
IDEs
– OmniSharp community
effort
Let’s
focus
on
Yeoman
+
VS
Code

21. Building
and
Running
– the
tools
• dnvm (.NET
Version
Manager)
• Run
multiple
versions
side
by
side
• Same
concepts
as
rvm and
rbenv for
Ruby
• dnu (.NET
Development
Utility)
• Build
and
publish
• Manage
dependencies
• dnx (.NET
Execution
Environment)
• Runs
web
and
console
apps
(non-­‐native)
• For
web,
on
a
Mac,
uses
kestrel
web
server

22. Demo
time!
Generating
an
app
with
yeoman
and
running
it

23. Building
and
Running
– the
tools
– RECAP!
• dnvm (.NET
Version
Manager)
• Run
multiple
versions
side
by
side
• Same
concepts
as
rvm and
rbenv for
Ruby
• dnu (.NET
Development
Utility)
• Build
and
publish
• Manage
dependencies
• dnx (.NET
Execution
Environment)
• Runs
web
and
console
apps
(non-­‐native)
• For
web,
on
a
Mac,
uses
kestrel
web
server
# make sure we’re on the latest
# engine
dnvm upgrade
# update dependencies
dnu restore
# build and run
dnx web

24. Anatomy
of
an
app
• Project.json
• Similar
to
node.js ‘package.json’
• Target
frameworks,
dependencies,
commands,
scripts
• A
DNX
app
is
basically
project.json and
a
startup.cs (or
other
name)
file
• Project.lock.json
• Similar
to
rails
‘Gemfile.lock’
• Contains
the
dependency
tree
generated
by
‘dnx restore’
• Used
at
app
boot
time
• Multiple
projects (aka
Solutions)
• global.json file
• More
info: http://docs.asp.net/en/latest/dnx/projects.html

25. Demo
time!
Deploying
to
Azure
Web
Apps
and
Linux
VMs

26. Last
words
and
testament

27. Choosing
the
right
.NET
for
You
• .NET
Framework
• Windows
only
• Fully
featured
• NOT
open
source
• .NET
Core
• CoreFX (libraries)
+
CoreCLR(small,
optimized
runtime)
• Cross
platform:
Windows,
Linux,
Mac
• Open
source
• Mono
• .NET
for
non-­‐Windows
platforms,
been
around
for
years
• Community-­‐driven,
supported
by
Xamarin
• Best
choice
for
mobile
apps,
BUT
not
ready
for
server/cloud
workloads
• Open-­‐source
• More
Info:
https://docs.asp.net/en/latest/getting-­‐started/choosing-­‐the-­‐right-­‐dotnet.html

28. • .NET
Core
apps
can
run
in
a
production
Linux
environment,
including
Docker
containers
(both
on-­‐prem and
in
the
cloud)
• Developers
can
edit,
compile
and
debug
their
.NET
code
on
Mac
OS
X
using
Visual
Studio
Code
(or
their
favorite
editor).
• Apps
built
using
platform-­‐agnostic
features have
identical
behavior
on
Windows
and
x-­‐platform
• .NET
Core
brings
along
existing
.NET
cloud
ecosystem
of
libraries
to
Linux
• Microsoft
will
support,
service
and
maintain
.NET
on
Linux
like
any
other
Microsoft
product
Plan
of
Record
(Microsoft’s
Promise
@
RTM)
It
Will
Work!
