Compiling Apps with .NET Native
.NET Native is a precompilation technology for building and deploying Windows apps that is included with Visual Studio 2015 and later versions. It automatically compiles the release version of apps that are written in managed code (C# or Visual Basic) and that target the .NET Framework and Windows 10 to native code.
Typically, apps that target the .NET Framework are compiled to intermediate language (IL). At run time, the just-in-time (JIT) compiler translates the IL to native code. In contrast, .NET Native compiles Windows apps directly to native code. For developers, this means:
Your apps feature the performance of native code. Usually, performance will be superior to code that is first compiled to IL and then compiled to native code by the JIT compiler.
You can continue to program in C# or Visual Basic.
You can continue to take advantage of the resources provided by the .NET Framework, including its class library, automatic memory management and garbage collection, and exception handling.
For users of your apps, .NET Native offers these advantages:
Faster execution times for the majority of apps and scenarios.
Faster startup times for the majority of apps and scenarios.
Low deployment and update costs.
Optimized app memory usage.
For the vast majority of apps and scenarios, .NET Native offers significantly faster startup times and superior performance when compared to an app compiled to IL or to an NGEN image. However, your results may vary. To ensure that your app has benefited from the performance enhancements of .NET Native, you should compare its performance with that of the non-.NET Native version of your app. For more information, see Performance Session Overview.
But .NET Native involves more than a compilation to native code. It transforms the way that .NET Framework apps are built and executed. In particular:
During precompilation, required portions of the .NET Framework are statically linked into your app. This allows the app to run with app-local libraries of the .NET Framework, and the compiler to perform global analysis to deliver performance wins. As a result, apps launch consistently faster even after .NET Framework updates.
The .NET Native runtime is optimized for static precompilation and in the vast majority of cases offers superior performance. At the same time, it retains the core reflection features that developers find so productive.
.NET Native uses the same back end as the C++ compiler, which is optimized for static precompilation scenarios.
.NET Native is able to bring the performance benefits of C++ to managed code developers because it uses the same or similar tools as C++ under the hood, as shown in this table.
| .NET Native | C++ | |
|---|---|---|
| Libraries | The .NET Framework + Windows Runtime | Win32 + Windows Runtime |
| Compiler | UTC optimizing compiler | UTC optimizing compiler |
| Deployed | Ready-to-run binaries | Ready-to-run binaries (ASM) |
| Runtime | MRT.dll (Minimal CLR Runtime) | CRT.dll (C Runtime) |
For Windows apps for Windows 10, you upload .NET Native Code Compilation binaries in app packages (.appx files) to the Windows Store.

Использование .NET Native
Недавно узнал о .NET Native, который позволяет компилировать .NET-проекты (C# или VB) в нативный бинарный код так, что моя программа становится независимой от .NET Framework и работает быстрее. Хотел бы изучить его, но решительно не могу найти .NET Native в моих Студиях (у меня 2017 Community и 2015 Professional). Подскажите, пожалуйста, где его искать и, если не сложно, кто сталкивался с .NET Native, как компилировать свои программы в нем?

How to configure .net native in Visual Studio 2015?
I read this guide for .net native, but I can’t found ‘Enable for .net native’ in popup menu. Should I install some extra plugin for VS2015 for compile with .net native?

This is the Project + Properties, Build tab of a project that was created with one of the Project > New > Visual C# > Windows > Universal project templates. Your machine must boot Windows 10, you may need to download the SDK separately if you installed VS2015 before Win10. Red arrows indicate the important parts, it should only be enabled for the Release configuration. The Platform setting matters as well, you need to test this for all platforms you wish to support (ARM, x86, x64).
Emphasis on the word test . The only reason you have the .NET Native toolchain on your machine is to verify that your app still operates correctly after the Store server recompiles the package you submitted. It is rather imperfect and cannot handle every possible Universal app. Several pain points, the major one is Reflection. The toolchain cannot see any types you load with reflection so cannot know that these types need to be converted to native code as well. Your app will fail miserably on the user’s machine if this isn’t taken care of.
Testing is simply a matter of running the Release build of your program through its paces, verifying that everything still works correctly. Start with the x86 platform first. You can cut a few corners when you next test x64 and ARM.
The package you actually submit to the Store is the one that is not built with .NET Native. Microsoft wants to keep the option open to improve the toolchain so needs the MSIL version of your assemblies. Version numbering matters, the last digit is reserved for the store. They’ll increment it when they rebuild your app.
In case it wasn’t clear yet: the .NET Native toolchain is only available for Universal apps that are distributed through the Store. Maybe it will be usable some day on regular apps but that day is far off, a fundamental different way to package such apps will have to come first.
