VS: No breakpoint code version differs from original version

Breakpoints are set, but cannot be interrupted, prompting that "the breakpoint code version will not be the same as the original version". In this case, it is generally generated bin\debug the following file does not match the actual code.

But this time there is no problem, re-update the program, clean up the project, No. As if the file code has been modified, VS does not recognize that it has been modified. Baidu a bit. This may be caused by confusion in the text encoding of the file. The solution is as follows:

1. Remove the wrong code file from the project

2. Re-create this file with VS, copy the code from the old code file into the file generated by the letter.

3. Recompile the project, OK
