How may an managed C# executable step into an Unmanaged C++ shared object's code using the Monodevelop debugger on a Ubuntu Linux 15.10 platform?

I was just notified that basically this is not supported there was some attempt to make this work, but it's lacking time and interest to make it work..

https://github.com/mono/debugger-libs/tree/lldb-debugging

PullRequests are always welcome

1. Load your C#/.NET solution into Monodevelop , build and run with debugging

2. ps -ef Please note that mono itself doesn’t fork processes except if your code does... your managed C# xyz.exe is loaded inside mono process and executed as one with no forking

3. Identify the process id(PID) of the mono process of interest" /usr/bin/mono --debug --debugger-agent which is 7575 in this actual example

4. The Unmanaged C++ shared object should be compiled with -g for creating an symbol table.
