Installation

Installing with dotnet tool requires the .NET 10 SDK. Running ilrepl requires the .NET 10 runtime. Loading NuGet packages also works with the runtime alone. Loading or rebuilding an SDK project requires the SDK selected by that project’s global.json. See Saving and sharing sessions. The front-end is a Native AOT executable; the part that compiles and runs IL is a small framework-dependent host that ships inside the package and runs on your dotnet.

dotnet tool

dotnet tool install -g ilrepl
ilrepl

On the platforms with a native package (Windows, Linux, macOS on x64 and Arm64) the SDK installs the Native AOT build. Everywhere else the portable build runs on the JIT.

From source

git clone https://github.com/willibrandon/ilrepl
cd ilrepl
dotnet run --project src/IlRepl

dotnet build also publishes the host into host/ beside the front-end, which is how the tool finds it. To point at a different host, set ILREPL_HOST_PATH.

Checking the install

ilrepl -e 'ldc.i4 6; ldc.i4 7; mul; ret'

prints
