.NET Framework 4.6 .NET Framework 4.6 In-place upgrade 100% compatibile con base esistente WPF per applicazioni Desktop ASP.NET 5 è supportato Nuovo compilatore (ROSLYN), Nuovo Jit (RYUJIT) Innovazioni del Linguaggio C# 6 Evolution in time .NET Framework 4.5.2 .NET Framework 4.5.1 .NET Framework 4.5

+ IL Compiler - ROSLYN Code Roslyn IL BCL Compilatore cross-platfom Open-Source Estendibile / VS Api Code (my.cs) + IL References (Modular, NuGet) BCL App Model Roslyn https://github.com/dotnet/roslyn

JIT Compiler - RyuJIT IL Compilatore JIT 64-Bit (altre piattaforme nel futuro) Compilazione 30% piú veloce Minore consumo di memoria Cross-platform Machine code 01010101010101 IL my.dll RyuJIT http://blogs.msdn.com/b/dotnet/archive/2013/09/30/ryujit-the-next-generation-jit-compiler.aspx Maggiore boot time Base framework A runtime

.NET Native tool chain IL Compilazione nativa con link statico delle dipendenze Runtime differente, NON utilizza il framework installato Maggiore ottimizzazione del codice macchina prodotto Sotto insieme di funzionalita’ .NET Windows Store App only Dipendenze IL my.dll .NET native runtime A compile time .NET Native 01 Solo UWP and ASP.NET 5 Passagigo intermedio, viene prodotta la normale DLL + MSIL, successivamente trasformata in codice macchina Boot time e tempo di serializzazione nettamente superiori, in quanto non deve piú compilare (no JIT)

.NET Framework 4.6 Shared WPF Windows Forms ASP.NET (4 & 5) Fully-featured and integrated .NET libraries and runtime for Windows Modular and optimized .NET libraries and runtimes Qui vediamo una panoramica tutta assieme Shared RyuJIT + SIMD Garbage Collector Runtime components Base class libraries NuGet packages Libraries Compilers .NET Compiler Platform (Roslyn) Languages innovation

Base Class Library (CoreFX) .NET Core (5 ?) My APP Base Class Library (CoreFX) API surface CoreClr CoreClr CoreClr .NET Core Windows Linux Mac OS X CoreCLR = runtime cross-platform per .NET Core CoreFX = insieme di librerie cross-platform

Project.json (ex app.config) ... "dependencies": { }, "commands": { "MyClass": "MyClass x y z" }, "frameworks": { "dnx451": { }, "dnxcore50": { } } … ??

.NET Core - Runtimes DNX = Ambiente di esecuzione (es: dnx.exe) C# Code DNX CoreClr Installato nella macchina Mac OS X Windows Linux Clr Mono Mono Win10 DNX = Ambiente di esecuzione (es: dnx.exe)
