Question

C#: why is there an asterisk on one of the code editor tabs in VS2005?

Does it have something to do with source control?

Answer 1

It means the file has been modified, but not saved. When you save the tab (file), the asterisk will go away.

This has nothing to do with source control.

Answer 2

It means there are unsaved modifications.

Press CTRL+s to save and it'll go away.

Answer 3

As the others said, it means unsaved changes. If you're not sure what you changed in the file, scroll down looking for yellow bars in the margin - they indicate lines with unsaved changes. Green bars mean lines with saved changes.
