PropertyChanged VS SharpLab

Add [AddINotifyPropertyChangedInterface] attribute to the class for change notification.

All the weaving libraries (also called weavers or addin) using Fody need to have the .Fody suffix, so it's quite easy to recognize them. As an example, if you ever had to implement INotifyPropertyChanged manually in a class with dozens of properties you would probably welcome weaving (and Fody) with open arms. By creating all the plumbing code directly in IL, libraries like PropertyChanged.Fody allows to inject the necessary notification code without the need to modify anything in the original source code.

You can rewrite auto-props (as used this this lib https://github.com/Fody/PropertyChanged) with Fody.

If you're not familiar with Fody and specifically the PropertyChanged weaver, I highly recommend checking it out: https://github.com/Fody/PropertyChanged

Now the ugly part - you need to implement INotifyPropertyChanged. It can be done either manually, or automated with this or this

https://github.com/Fody/PropertyChanged and Android background makes WPF pretty easy. At least the surface level stuff.

If you really don't want to deal with it ever again, just add this Fody - PropertyChanged NuGet package. Any class that inherits from INotifyPropertyChanged will be updated at compile time to inject in the boilerplate code for handling the property change and you never even need to think about it again. All you need to do is just add plain old properties. The only downside that some people see is that it is not immediately transparent as the change notification code is injected in during compile and is not in source code.

And GitHub is the place where employees of billion dollar companies pester unpaid maintainers because they won’t support a 12 year old version of .NET

Do these all compile to the exact same thing?

Yes, so you are right.

Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

One results in MOVSX, the other in MOVZX [1]. The difference thus is sign/zero extension when moving to the larger register. However, they seem to perform pretty much identical if I'm reading Agner Fog's instruction tables correctly.

If you don't have an IDE, you can use SharpLab.io or dotnet fiddle

The closest online tool I can think of would be SharpLab, but you can only choose between Roslyn's git branches instead of C# versions.

Your code is destructuring two properties and discarding one of them. It doesn't work with a single property: https://sharplab.io/#v2:C4LgTgrgdgNAJiA1AHwAICYAMBYAUBgRj2Nw...

I think that records don't generate a deconstruct method when they only have one property, but even if you manually define one you'll get an error on `var (varName) = ...`

- LinqPad is great and I love, but, IMO, it is not the best tool to start with. It does not provide intellisense or debugger in the free version. Assuming you do not want to pay for this licence just to play a little with the language, I'd suggest https://sharplab.io/. It is not as powerfull as LinqPad, but at least it gives you suggestions.
