You are familiar with FreeAndNil(), but do you use it? How often? Are you using it right? As with most things in software development, it is a complicated topic. So let’s see what the experts have to say. We are going to debate the details in a friendly discussion with some of your favorite MVPs.

I’ve left the legend of that the charts mean off for now, you need to join the webinar to see the details, but the use of FreeAndNil() is pretty evenly split if we lump the responses into generalities for for and against.
If we break things down into details though it is a little bit more nuanced. Again, without the legend, yet.
Making assigned checks is similar, but a little more pronounced differences.

Façam um Webinário sobre criação CORRETA de componentes e OTA. Falar sobre FreeAndNil e Assigned qualquer um fala. Quanto mais pessoas souberem como criar componentes da forma correta e quanto mais pessoas conhecerem o OTA, mais o ecossistema Delphi crescerá

[Can we] do a webinar on CORRECT component creation and OTA? Talking about FreeAndNil and Assigned anyone talks. The more people who know how to build components the right way and the more people who know about OTA, the more the Delphi ecosystem will grow.
Hi Carlos, I’ll make sure the suggestion to have a webinar on correct component creation gets noted. There have been quite a few discussions on that topic over the years including several by prominent component creators such as the legendary Ray Konopoka who, quite literally, wrote a whole book about it. Topic suggestions are always welcome for the webinars, and we do try to pick ones which people will find engaging and informative and this one on FreeAndNil was one which seemed to be something a lot of people thought would fall into that category.
