2. Show of hands: š Who uses .NET Core? š Who is planning to use .NET Core? š Who just wants to know what all the fuss is about?
3. Where does .NET Core fit in? .NET Standard .NET Framework Windows .NET Core Linux macOS Windows
4. Reasons NOT to port š Not enough APIs š Desktop applications WPF / WinForms š ASP.NET Web Forms š Entity Framework 6 many-to-many relations š You’re happy with the status-quo .NET Framework
5. Reasons to port š Highly scalable web apps š Apps on Linux Docker / microservices š Side-by-side deployments š Self-contained deployments š Performance
6. Looking ahead: .NET Core 3.0 https://blogs.msdn.microsoft.com/dotnet/2018/05/07/net-core-3-and-support-for-windows-desktop-applications/
7. Where does .NET Core fit in? .NET Standard .NET Framework Windows .NET Core Windows macOS Linux
8. .NET Standard Platforms .NET Standard 1.0 1.1 1.3 1.4 1.6 2.0 .NET Core 1.0 1.0 1.0 1.0 1.0 2.0 .NET Framework 4.5 4.5 4.6 4.6.1 4.6.1 4.6.1 Mono 4.6 4.6 4.6 4.6 4.6 5.4 Xamarin.iOS 10.0 10.0 10.0 10.0 10.0 10.14 Xamarin.Mac 3.0 3.0 3.0 3.0 3.0 3.8 Xamarin.Android 7.0 7.0 7.0 7.0 7.0 8.0 Universal Windows Platform 10.0 10.0 10.0 10.0 10.0.16299 10.0.16299
9. .NET Framework 4.7.1 š Implements .NET Standard 2.0 š Instead of tooling required for 4.6.1+ š Clean bin folder outputs š No binding redirects š https://github.com/dotnet/standard/issues/514
10. Let’s talk binding redirects š No more in .NET Core š Still has if targeting .NET Core on top of .NET Fx š “Deep-dive into .NET Core primitives: deps.json, runtimeconfig.json, and dll’s” https://natemcmaster.com/blog/2017/12/21/netcore-primitives/
11. .NET Core
12. Great things before .NET Core 2.0 š `dotnet` CLI š Side-by-side š Self-contained deployments š Cross-platform support š Docker container images š New csproj file system
13. What’s new in 2.0 š .NET Standard 2.0 š Windows Compatibility Pack š .NET Framework libraries that are in .NET Standard š Visual Basic in addition to C# & F# š `dotnet restore` runs implicitly
14. Windows Compatibility Pack š Access to 20,000 more APIs than are available in .NET Core. š Windows-only and some cross-platform š System.Drawing namespace, the EventLog class, WMI, Performance Counters, Windows Services, and the Windows registry types and members https://blogs.msdn.microsoft.com/dotnet/2017/11/16/announcing-the-windows- compatibility-pack-for-net-core/
15. What’s new in 2.1 š Faster builds š Global tools (like `npm install –g`) š Roll forward (minor versions, e.g. 2.0 à 2.1) š Self-contained application servicing (`dotnet publish`) š Visual Basic in addition to C# & F# š `dotnet restore` runs implicitly
16. ASP.NET Core
17. Great things before ASP.NET Core 2.0 š New middleware based pipeline š Kestrel server š Configuration š Logging abstraction š Merged namespaces for ASP.NET MVC and Web API š JavaScript Services (Angular, React, Webpack)
18. What’s new in 2.0 š Razor Pages š ASP.NET Core metapackage š Runtime Store š Automatic Razor view precompilation
19. What’s new in 2.1 š SignalR š Razor class libraries š Identity UI library & scaffolding š HTTPS on by default & tooling š GDPR š Integration tests š IHttpClientFactory and HttpClient performance improvements š OpenAPI (Swagger) conventions for easy generation
