RE: Step by Step skips large chunks of code

OK, I created a new project and copied the original code back to it.

The interesting thing is that it still skips code during debug but not
nearly as bad as the original project. That makes no sense to me at all!

Hello Scott,

Thanks for your post.

One of the reason for such kind of problem is code optimized. Compiler will
decide to skip some code if they are not necessary to execute.
In order to check if the project code has been optimized. Could you please
check the following settings:
1. Is the project compiled as debug mode or release mode?
2. In project properties page, switch to [Build] tab, and check if the
[optimize code] option is checked?

Visual Studio also provide a powerful tool for us to check if the C# code
has been correctly complied into assembly code.
When a breakpoint is hit, open menu [Debug] / [Windows] / [Disassembly]. It
will switch the source code tab to a Disassembly tab. Inside the
Disassembly tab, we could see that every C# statement with its associated
assembly code below. If there is no assembly code below the C# code, that
tells us this C# code has been optimized. We could also use F10 (Step Over)
to debug it at assembly code level to check if the debugger skips assembly
code.

The solution to code optimized is to uncheck the [optimize code] and switch
compile mode to debug.

If the solution does not work, I would suggest you to create a new project
with default project settings and copy the debugged code into the new
project. Debugging the same code with another project let us eliminating
the project settings' impaction.

In the meanwhile, you could send me your project zip file, so that I could
help you analyze the code and project settings. (My email address is

Please feel free to let me know if you have any question. I will be more
than happy to be assistance.
