问题 I'm a bit confuse about how to implement async await approach and wait for results before continuing.

Something like this: Private Sub GetParseExpressionResults() If Not isParseExpressionSupported Then Return End If 'Cleaning collections Me.parseExpressionItemsTo.Clear() Me.parseExpressionItemsCC.Clear() Me.parseExpressionItemsSubject.Clear() 'Getting list of
