At The Bit, we understand how overwhelming  it can be to navigate through all the different tutorials online and try to teach yourself programming skills alone.

That’s why we’ve created The Bit — we’ll match you to a peer with similar skills and interests to take the tutorial of your choosing.

Manage events entities is pretty easy. You define few informations like a subject, a content, and maybe the most important, dates (a start and a end date of course).
You’re ready to create calendar or timeline features. Baooom! Now you need to be able to create recurrent event ! And everything is going to break.
I’ve work on this kind of feature, and here are my small advices 

                   //var dataS = childNode.Attributes.First(x => x.Name == "data-s");
                    var dataS = childNode.Attributes.First(x => x.Name == "ng-click");
                    var startTime = new Regex("(?s)start=(.+?)'").Matches(dataS.Value)
                                                         .OfType<Match>()
                                                         .First()
                                                         .Groups[1]
                                                         .Value;
                    itemsList.Add(new TranscriptItem
                    {
                        StartTime = double.Parse(startTime),
                        Text = HttpUtility.HtmlDecode(childNode.InnerText.Trim())
                    });

The preview release of PowerShell 7.1 includes .NET 5 preview 1. Starting with PowerShell 7.0, devs have shifted to align with .NET’s release and support life-cycle more closely. PowerShell 7.1 is expected to become available within a week or two of .NET 5’s release date of winter 2020 and align with their annual release cadence going forward.
