NCover Error?

time to read 1 min | 130 words

I just started getting wildly different coverage precentage from NCover on identical runs. No two runs agree with each other, but I can't for the life of me figure why.

Run 1: 89.58%
Run 2: 75%
Run 3: 54.17%
Run 4: 95.83%

etc...

I can reliably repreduce this problem by doing the whole build cycle, but I've no idea how to fix this.

[Update: I seemed to have a file with ".instrumated" extention somewhere in the code, and removing that seem to fix that]

[More updates: It wasn't that, still getting wildly differing output from the same tests.]
