ArgumentOutOfRangeException	deleteSpan.The end of the span is greater than the length of the buffer.

Remarks

This is a shortcut for creating a new ITextEdit object, using it to delete the text, and then applying it. If the deletion fails on account of a read-only region, the snapshot returned will be the same as the current snapshot of the buffer before the attempted deletion.
