Free NCrunch alternative
c#, code-coverage, ncrunch, visual-studio
Solution
From what I've read, most people are in the same boat and are moving to ContinuousTests. I do not think there is a perfect replacement... yet.
Here is a decent comparison between NCrunch and ContinuousTests
Update
Upon recent usage of ContinuousTests with VS2012 I have decided to uninstall. There was too much friction to get it running. I believe it needs an update to support VS2012 properly.
Problem
Since NCrunch has left the free market, I was looking for a similar tool for code coverage marking, and continous testing like NCrunch edit: I'm using VS2012 update: I've been using ContinuousTest for a while now, it's OK, but I think it lacks feedback when I write code. The feedback is good when I write tests, but when I break a test (while editing source code) it won't tell me that the test broke (in the margin, like it does for NCrunch). So if anyone knows other tools, I'm still listening.
