Question

Like this:

Cursor.Current = Cursors.WaitCursor;
try {
  . . .
} finally {
    Cursor.Current = Cursors.Default;
}

or this:

try {
  Cursor.Current = Cursors.WaitCursor;
  . . .
} finally {
    Cursor.Current = Cursors.Default;
}

?

There’s no harm in putting the first cursor assignment inside the try block. As others have noted, if you know for sure that the assignment can never throw an exception, it doesn’t strictly need to be inside the try block. If you’re not sure, it’s better to put it inside the try block.

As a general coding pattern, if you’re unsure whether a statement could throw an exception, put it inside the try block. It’s better to put it inside the try block and not need it than to assume/guess wrong and put it outside the try block when you really do need it inside.
