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

Click Rebuild Solution.

Answer 2

This can also happen when your Debug solution configuration is up to date, but you try to debug the program in Release configuration (if that is not also up-to-date)... or vice versa.

You can switch back and forth between running in Debug or Release configuration using the drop-down next to the green 'play' arrow at the top of the screen.

Answer 3

I'm running into similar problems debugging a C# program with Visual Studio 2010 on an XP machine. The debugger just randomly skips to some other line or the next break point.

It seems that Microsoft has released a Fix for this in the SP1.

Answer 4

Do you have optimizations turned on? If the program is highly optimized, the order of execution can be thrown off, and things can be expanded or rearranged in ways that are not always clear.

Answer 5

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.

Answer 6

I had a similar problem in Visual C++ 2008 on Windows 7 32-bit recently. Several minutes before the problem first appeared, a system dialog window “VC.exe encountered a problem and needs to quit” was displayed but the Visual C++ window seemed to survive.

After the problem first appeared, I tried several ways to getting it back to work like rebuilding the solution or restarting Visual Studio. However, it continued to behave strange: It failed to link with an object file I hadn’t touched for weeks, displayed “The breakpoint will not currently be hit. The source code is different from the original version.” etc.

Nothing helped until I rebooted the computer and finally rebuilt the solution (twice, actually).
