Example of how to build a .NET native library for another programs

.NET Library for Native Apps

dotnet AOT support is now out, this project will be archived as it is now officially suported

Steps from scratch

• Create a new project

  dotnet new classlib -o DotNetLib

• add NativeAOT support by creating a nuget config

  cd DotNetLib
  dotnet new nugetconfig

• Add the following to the nuget.config file:

  <add key="dotnet-experimental" value="https://pkgs.dev.azure.com/dnceng/public/  _packaging/dotnet-experimental/nuget/v3/index.json" />

• add a reference to the compiler

  dotnet add package Microsoft.DotNet.ILCompiler -v 7.0.0-*

• then you can publish the dll like this

  dotnet publish /p:NativeLib=Shared /p:SelfContained=true -r <RID> -c <Configuration>

Cpp steps

• make and build the native executable

  meson builddir
  meson compile -C builddir

• put the library in the executable generated by meson (buiddir/cpp)
• run it

  ./builddir/bin/<executable>
