You are using the old version of SOS (that came with the .NET framework itself).
Consider using the newer version that comes with WinDbg, in clr10 subdirectory -

AFAIK live source level debugging is not possible with SOS
(you have to work on disassembly level and use SOS commands to see
where you are in the sources).
