Reason: The currently debugged program does not match the symbol table pdb in the working directory
Symbol table.pdb and breakpoint debugging
The symbol table is a mapping table made by compiling and linking the executable file (.exe) and the source code. It stores the names and addresses of global variables and functions; the names and stack offsets of local variables; the data type definition of class and struct data;
Knowing the reason, the solution is
Solution: Make sure that the symbol table in the current working directory and the process currently being debugged are the same set
Especially the debugging method of attaching to the process, you need to find the correct process
view working directory
Solution Explorer - "Right click on the project -" Properties - "Debugging:
View the currently loaded symbol table
Turn on debugging-"debugging-"window-"module (or hotkey Ctrl+Alt+u)
and you can see the currently loaded symbol file in the "symbol file" column (symbol file)
