I am curious to know if there is a way to edit code in C# VS 2008 right when it has hit a breakpoint and I am walking thru the code… can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement … can I modify the if statement….etc)?
So far, I have to stop running VS, modify the code, then hit F5 and wait till the breakpoint is hit again.
When the breakpoint hits, and I am walking thru the code, and I attempt to edit the code, I get a message “Changes are not allowed when the debugger has been attached to an already running process of the code being debugged was optimized at build or run time.”
There are only a few reasons I know of why Edit+Continue would be disabled in the Debug build. First and foremost is a 64-bit operating system, E+C only works for 32-bit code. Fix that with Project + Properties, Build tab, Platform Target = x86.
It is also an option that might have been turned off. Tools + Options, Debugging, Edit and Continue, Enable checkbox.
If this doesn’t help, tell us a bit more about the kind of code you’re debugging, the project template you selected when you started the project, how you got the debugger to break and a stack trace copied from the Call Stack window.
