Using MonoDevelop to Debug Executables with no Solution Files

Every once in a while I need to debug some Mono program that does not come with a solution. Either a program that was compiled using a Makefile or an executable that I installed with RPM on my system.

Sometimes I would end up cretaing MonoDevelop solution that contained every source file, command line option and resource that I meticulously copied from the Makefile. In other words, I was in for a world of pain just to be able to use MonoDevelop's awesome debugger.

Lluis offered this solution, and I am blogging it hoping that it will help someone else in the future. Follow these steps to debug a Mono executable and set breakpoints on the source code or class libraries source code:

1. Create a Generic Solution

Select File/New Solution and select Generic Solution:

2. Open the Project Properties

Double click on your project, in my case I called the project "compiler":

3. Add an Execute Custom Command

In your project select Custom Commands:

Add a custom Execute command by selecting it from the "Select a Project Operation" option and point to your Mono executable:

4. Load source files

Use File/Open to load the source file where you want to set a breakpoint (the executable source or some class library source) and set your breakpoints:

Then use Run/Debug to start your program in debugging mode (Linux and Windows users can use F5, MacOS X users can use Command-Return).
