1. .NET Native & CoreRT

2. .NET Native
Ahead Of Time (AOT) compiler for .NET UWP applications and the associated runtime.
Compiles IL binaries
Produces platform specific executable (X86/AMD64/ARM)
.NET runtime optimized for AOT

3. Application at runtime
GC and other low level code
Same GC as .NET Core
The only part written in C/C++ (mrt100_app.dll)
Runtime specific FX
CoreLib, reflection, type system, …
CoreFX
– shared with .NET Core
Compiler generated code
Interop, serializers, …
Application code

4. Compiler components IL to IL transformations
Global analysis of the app and the FX it uses
Tree shaking
Determines what reflection metadata to include
Code generators – interop, serialization, …
NUTC – compiles IL to platform specific assembly
Binder – produces the final platform specific binary

5. Shared library
Core portions of the framework are precompiled into a platform specific SharedLibrary.dll (native Windows .dll)
Applications call into it instead of including the code in them
SharedLibrary.dll is shared between all apps on the machine
Reduces size on disk for the apps
Reduces the compile time for the apps
Speeds up app startup (less IO if SharedLibrary.dll already loaded)

6. Windows Store integration
Used by all managed applications in the UWP Windows Store.
Integrated in VS for UWP App development.
Part of the Windows Store ingestion process
Managed apps are submitted to store as IL
The store compiles them with .NET Native for all target platforms

7. Coming to .NET Native .NET Standard 2.0 support
UWP apps will be able to use the full set of .NET Standard 2.0 APIs
UWP apps will be able to use any library which targets .NET Standard 2.0
Bug fixes, improvements, …

8. CoreRT project
Cross-platform open source evolution of .NET Native for UWP
Work in progress, not a shipping product
Initial target: Simple microservices on Windows/Unix x64
Full AOT toolchain and runtime
RyuJIT used as code generator
Platform linker produces the final binary
