* Debugging information Compile your programs using the `-g' flag in MCS, that will generate a file with the extension .dbg containing the dwarf symbols for your executable. To get stack traces with line number information, you need to run your program like this: mono --debug program.exe Notice that the program will need to be compiled with the -g flag and that running with --debug will slow down the execution. * Mono Debugger A new debugger has been created in C# and using Gtk# for its user interface, this will simplify the debugging of CLI applications. Stay turned for its first public release.
