.NET Core 3.0 introduced the ability to create ReadyToRun (R2R) binaries, aimed at improving the startup performance of applications.
Usually, a regular .NET assembly only contains managed code (Intermediate Language Code, or IL) which is compiled to native code by the just-in-time compiler (JIT) after the application starts. Assembly built as ReadyToRun not only contains managed code, but also parts of it already precompiled to its native form – this greatly reduces the work required by the JIT to load your application, because it was done ahead-of-time.
ReadyToRun is only available when publishing a self-contained .NET Core application, targeting a specific environment and bitness.
This directory contains two examples of integrating SmartAssembly into .NET Core 3 ReadyToRun build:
- simplified-example - .NET Core 3.1 console application protected by SmartAssembly, published as ReadyToRun.
- executable-with-library - .NET Core 3.1 console application with reference to .NET Standard 2.0 library, both protected by SmartAssembly, published as ReadyToRun.
Execute the publish-and-run.bat file from either example, to build, publish, and run the application protected by SmartAssembly.
Follow our documentation to see how to protect your ReadyToRun assembly by integrating SmartAssembly into your build process.
