#Net5 – C#9 “records” and “deconstruction” super cool feature 🆒🆒🆒

Hi ! I’m still learning about C#9, and there is a lot to learn about records. And, between all this information, I Just learn a super cool feature related to records: deconstruction. Let’s start with a simple record definition for a pet. This one includes pet’s name and pet’s age: public record Pet { public string Name { get; init; } public int Age { get; init; } public Pet(string name, int…

#Net5 – C#9 “Init-only properties” are super cool 🆒🆒🆒

Hi ! So this one does not fit in the line “readability improvement”, however is a nice step in order to write cleaner code. Yes, I know that doesn’t make sense, let me try to explain. Let’s start with a simple class with 2 properties. Interesting enough the property Age has a new accessor [init] to describe the property as a read-only property: class Pet { public string Name { get; set;…

#Net5 – C#9 logical operators “is” and “is not” are super cool 🆒🆒🆒

Hi ! In the line of good features, that are also nice to read, the new use of is and is not is a huge improvement in readability. As usual, old school validation for objects and types: // old school if(!(testObj is MyClass)) {...} And now, we can type the validation with some style: // C# 9 style if(testObj is not MyClass) {...} I like this new one 👆, now null / not null and other…

#Net5 – C#9 target-typed new expressions are super cool 🆒🆒🆒

Hi ! I know I’m late to the party here, however I’m still enjoying some of the new C# 9 features a lot. I just realized that now, I can create objects in a different way, which is still super clear to read. Disclaimer: some of the new features are cool, however my gut told me that they will make code harder to read. I also understand that I have 20 years of writing C# code in my back, so I need…

#C#9 – Records, with and this. A super cool mix

Hi ! Our next podcast episode is focused on .Net 5. We had an amazing chat around a lot of features, and of course, C# 9 was part of the conversation. I got this amazing post [C# 9.0: Records – Work With Immutable Data Classes] from Tomas Huber, in my reading notes and working with records is something that I wanted to test. In a few words, a record is an immutable class. Which is super cool,…

#Net5 – Migrating a fully functional Windows Form app to Net Framework 5 in 10 minutes !

Hi ! TbVolScroll is a super cool project, take a look 👇 Simple utility to enable volume control when your mouse cursor is positioned above the taskbar. Hold the left ALT key to enable precise volume control (decrease/increase volume by 1%). Standard volume step is 5%. The volume bar will follow the cursor when it’s moved. By default, if the volume is lower than 10% precise volume control is…

#OpenCV – Open a video file 🎥 and save each frame as a PNG 🖼 file to a folder 📂#Net5

Hi !

A couple of days ago I wrote this post, and made the sample with Python. So today, same scenario, however with C# 9 and Net5.

This is a non-usual scenario, however I’m on a point where I need to extract all the frames from a video file. The reason: some of these frames will be used to train a Machine Learning model.

There are tools that can do this, however it’s a nice moment…
