Strange bug in Visual Studio

OK, It has been a long time I never post about programming here although I am supposed to be software engineer (or probably more IT consultant for last 1 year). I encountered this strange bug which cause cannot be identified.

So, basically my program is supposed to compute certain amount of money to certain group of people. There is a case whereby the computation went wrong and I need to check this particular person by inserting breakpoint to check local variable…

Breakpoint Bug 1


I am supposed to insert break point at line 210, so I saved the file, cleaned and rebuild the project, put the break point there and then start debugging my C# console application project.

Then, to my frustration, the break point always shifted to next line upon program execution:

Breakpoint Bug 2


I tried to restart the Visual Studio, reclean and rebuild solution, playing around with project Properties page and so on, with no success. I have also tried to tweak the debugging statement:

By adding curly bracket:

Breakpoint Bug 3

By adding another variable:

Breakpoint Bug 4

Still no success….Then after around 1 hour, I found that I need to modify the statement to the following…

Breakpoint Bug 5

It turned out that Microsoft Visual Studio cannot insert break point to the variable assignment to constant value…which is very strange. After around 10 years studying programming, I just knew about such limitation -.-.
