3. A SHOrt aural history of .Net
.NET 3.0 (Same CLR)
.NET 3.5 (Same CLR)
.NET 4.0
.NET 4.5
.NET 4.6
.NET 4.7
ALL WINDOWS

4. What do we mean by “cross platform?”
Not just Windows
Devices
Linux
Tizen (Samsing appliances)
Ubuntu
Debian
Red Hat
MacOSX
Docker

5. What about Mono?
Mono is an open source implementation of the .NET Framework.
Goal is to run .NET applications across multiple platforms.
Mono helped light the push towards .NET not being “only Windows”

6. .NET Standard
A specification of .NET APIs that would be available in any environment that supported the standard.
Currently, we’re at .NET Standard 2.0.
Any libraries built pre-.NET Standard 2.0 can probably run on .NET Standard 2.0
We’ll show you how to figure that out

8. .NET Standard is not perfect

9. Supported application types
Web applications (ASP.NET)
Console Applications
No Window Services
No GUIs
WinForms
WPF / UWP (XAML)

10. DEMO: Let’s quickly build a Cross Platform app
“Hello World”, of course

11. Demo action plan Create an app in Windows Run on Windows
Run on Linux (with .NET Core installed)
Run on Linux (without .NET Core install – Whaaa?)

12. Portability Analyizer
The “Will This Blend?” for .NET Standard
us/dotnet/standard/portability-analyzer

13. .NET Core Runtime identifiers Catalog
Used to target where your application should run.
Great for self-contained apps!
