Test solution

Build the attached solution. Set a breakpoint in MyClass.cs:42. Debug it with
mdb. Try to step into the Run method. The debugger steps into the runtime
instead of the Run method. This is the sequence:

lluis at linux-zn6q:~/Projects/borra343/borra343/bin/Debug> mdb borra343.exe
Mono Debugger
(mdb) b MyClass.cs:42
Breakpoint 2 at MyClass.cs:42
(mdb) r
