break point is not hitting while debugging

Question

Possible exact duplicates:

Reason for VS.NET ‘current breakpoint will not be hit’ warning?
Why does Visual Studio sometimes not go to my breakpoints?
Why would the debugger not be stopping at a breakpoint in my ASP.NET application?

while debugging,the modified source code the break point is not hitted for a particular aspx page and the following error is shown in the break point

"the break point will not be currently hit.the source code is different from the original version"

but for other page it is working fine.

For everyone else, make sure your are on Debug configuration xD That was my issue! — Ghasan غسان, Feb 01 '20 at 12:18

It worked for me. Try this.

First try rebuilding your project by right mouse click the project > Rebuild If that doesn't work, try a clean of the project (right mouse click on the project > clean)

If that didn't work check this:

1- Right mouse click your project
2- select [Properties]
3- select [Build] tab
4- make sure [Define DEBUG constant] and [Define TRACE constant] are checked

5- Click the [Advanced] button at the bottom of the Build tab page
6- Make sure that [Debug Info:] is set to [full]
7- Click [OK] and rebuild the project ;-)

Hope that works for you! (step 6 generates the .pdb files, these are the debugging symbols)

This worked well for me too, a lot simpler than the selected answer imo. – Probably Mar 22 '17 at 13:23

This particular part from answer above was the solution for me: -> Click the [Advanced] button at the bottom of the Build tabpage -> Make sure that [Debug Info:] is set to [full]. Mine was set to "None" - therefore PDB (Debugging Info) was not generated – Natasha Voloshyna Aug 27 '19 at 20:02

Some times this occurs if the sourcecode is been copied from the network folder, it messes up the symbol settings. Below solution works for me everytime

In debug mode, select debug->windows->modules
Check your dll symbolStatus . Make sure that it is loaded into the project (i am sure now the status is not loaded )
Right click your dll, click symbol settings.
And manually add your symbol path (.pdb file path)
And again right click the dll, and click load symbols

Hope this helps

That suggests the build that's running doesn't match with your code.

Try performing a "clean", make sure that you've stopped any previous debugger sessions etc, then rebuild and retry.

make sure there are not instances of w3wp.exe running. I had several and closing them fixed it for me.

This problem occurred to me when I had copied the project. In fact, by opening the old code file if breakPoint is inserted, you will see that it will work. So learn the correct copying method.
