How to update text in a file?

Question

C++ / C#

The application executes the task by logging the state of the task to a file at regular intervals.
The file is written via File.WriteAllText
The problem is that when the application stops, the file is deleted, and a new one is not created in its place. Is there any easy alternative to do the same without this bug?

Answer 1

The problem is that when the application is stopped, the file is deleted

And shouldn't. It means there is a deletion somewhere. Is your code?
