Fody VS PropertyChanged

While Fody works at binary (MSIL) level, Metalama Compiler is a fork of Roslyn and allows for AST transformations, at the C# level.

As an alternative to PostSharp you may take a look at Fody.

Working with IL weaving as part of the building process is quite complex though, and this is where Fody enters into the picture. Fody is an extensible tool that allows to simplify the weaving process by taking care of all the heavy lifting.

Fodyplugins can modify exists code during compilation.

I've seen coworkers using Fody for such MSIL weaving stuff, but I have a bad feeling about this. It's a little bit like jailbreaking your phone. Cool stuff ahead, but voids warranty.

Implement your own (in C++/outside dotnet/CLR) IHostAssemblyManager stuff, this is the "replace/bypass how assemblies are loaded" trick. There used to be a prebuilt thing on the old old codepages, but I can't find it. I wonder if newer code/assemblie weavers such as Fody can do the similar thing?

Great place to start is https://github.com/Fody/Fody and existing 'addins' - fody does it at compile time - generally quite useful for your own code if you want to dip into aspect oriented programming.

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
