Edit and continue could not apply the changes you made to your code. This may be a temporary condition. Sometimes Edit and Continue cannot apply code changes immediately, but can apply them later during the debugging session (for example, after completion of the current call to the procedure now executing). For more information, see Limitations of Edit and Continue.
Rebuild
Click this button to terminate the debugging session and build your code with the changes.
Ignore
Click to ignore the message and continue debugging. Code changes will not be applied immediately, but may be applied at a later point during the run of the program (for example, after the current call).
Cancel
Cancel the Step operation that was being performed.
