JetBrains dotTrace, is it possible to profile source code line by line? else I need another tool

Question

I am using JetBrains dotTrace, I've profiled my app which is entirely CPU bound. But the results as you walk down the tree don't sum to the level above in the tree, I only see method calls not the body lines of the node in questions method.

Is it possible to profile the source code line by line.

i.e for one node:

• SimulatePair() 99.04%
  --nextUniform() 30.12%
  --IDCF() 24.08%

So the method calls nextUniform + IDCF use 54% of the time in SimulatePair (or 54% total execution time I'm not sure how to read this) regardless what is happening the other 46% of SimulatePair I need some detail on a line by line basis.

Any help or alternative tools is much appreciated.

Thanks

Here's the method I use. It's simple, free, gives you line by line info, and suffers no such confusions.

For the benefit of future searchers, dotTRACE 4.0 BETA supports line-by-line profiling. It helped me find an endless loop.
