Introduction

Netcore support in mono consists of two parts:

The runtime compiled in netcore mode
An implementation of System.Private.CoreLib

Building

Everything below should be executed with the current dir set to 'netcore'.

For bootstrap, do

./build.sh

To rebuild the runtime, do

make runtime

To rebuild System.Private.CoreLib, do

make bcl

These two targets will copy the results into shared/Microsoft.NETCore.App/.

Running with netcore

Running through the 'dotnet' tool.

Run dotnet publish -c Release -r osx-x64 to create a published version of the app. Copy

into

bin/netcoreapp3.0/osx-x64/publish/libcoreclr.dylib``` Copy

to

bin/netcoreapp3.0/osx-x64/publish```

Running with the mono runtime executable

DYLD_LIBRARY_PATH=shared/Microsoft.NETCore.App/ MONO_PATH=shared/Microsoft.NETCore.App/ ../mono/mini/mono-sgen --assembly-loader=strict sample/HelloWorld/bin/netcoreapp3.0/HelloWorld.dll

How to set up managed debugging

Change the DebugType to full in your .csproj

<DebugType>full</DebugType>

Enable debugger agent using the environment variable MONO_ENV_OPTIONS

export MONO_ENV_OPTIONS="--debug --debugger-agent=transport=dt_socket,address=127.0.0.1:1235,server=y,suspend=y"

Run

./dotnet --fx-version "5.0.0-alpha1.19409.2" sample/HelloWorld/bin/netcoreapp3.0/HelloWorld.dll
