Windbg - Cannot see line number in managed call stack

Question

Hi, I am using Windbg to analyze a crash that was created from managed code. I am loading SOS and mscorwks and using the !pe command. I can see the managed callstack, with module and function names but no source file and line number information. I can see this information for native crashes, but not for managed. I don't know if it is the PDBs or something else. when I did lm, it says I have private pdb symbols for my managed app. Any help is highly appreciated. Thanks
