Visual Studio 2010 debugger skipping

Question

Occasionally during debugging the debugger skips forward randomly. Sometimes I Step into a function inside of another function and instead of going to the next line it skips

Answer 1

This can happen when the debugger is running against pdb files that don't match the source code you are looking at. Make sure the bin (or where you are running from) is up to date and was built from the same source code you are running in the debugger.
