Debugger for .NET Core runtime

The debugger provides GDB/MI or VSCode Debug Adapter protocol and allows to debug .NET apps under .NET Core runtime.

Build

Switch to netcoredbg directory, create build directory and switch into it:

mkdir build
cd build

Proceed to build with cmake.

Necessary dependencies (CoreCLR sources and .NET SDK binaries) are going to be downloaded during CMake configure step. It is possible to override them with CMake options -DCORECLR_DIR=<path-to-coreclr> and -DDOTNET_DIR=<path-to-dotnet-sdk>.

Ubuntu

CC=clang CXX=clang++ cmake .. -DCMAKE_INSTALL_PREFIX=$PWD/../bin

macOS

cmake .. -DCMAKE_INSTALL_PREFIX=$PWD/../bin

Windows

cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_INSTALL_PREFIX="$pwd\..\bin"

Compile and install:

cmake --build . --target install

Run

The above commands create bin directory with netcoredbg binary and additional libraries.

Now running the debugger with --help option should look like this:

$ ../bin/netcoredbg --help
.NET Core debugger

Options:
--attach <process-id>                 Attach the debugger to the specified process id.
--interpreter=mi                      Puts the debugger into MI mode.
--interpreter=vscode                  Puts the debugger into VS Code Debugger mode.
--engineLogging[=<path to log file>]  Enable logging to VsDbg-UI or file for the engine.
                                      Only supported by the VsCode interpreter.
--server[=port_num]                   Start the debugger listening for requests on the
                                      specified TCP/IP port instead of stdin/out. If port is not specified
                                      TCP 4711 will be used.
