How does it work?

1. Add PostSharp to your project and annotate your code with [CustomAttributes]. 2. The C# or VB compiler builds your code into binaries. 3. PostSharp analyzes the binary and injects the implementation of the aspects.

At run time, your application is fast because the hard work was done at build time.
Your source code remains crystal clear.

"PostSharp is a pretty amazing piece of software."

Stay DRY with aspect oriented programming by injecting repetitive code directly into your application. Abstractions like AOP are the whole point of what the computer is supposed to do for us, work that’s not fun, like logging and transactions. So why not hide that?

"PostSharp should be part of every C# developers' toolset."

PostSharp is amazing! If you are not using it, you should! The amount of code that can be reduced in logging alone is worth the price! I believe that PostSharp should be part of EVERY C# developers toolset.

"Working declaratively is a dream!"

PostSharp is the best way to implement cross-cutting functionalities in a very elegant and efficient way. And when you want to enforce some design rules in your code, working declaratively is a dream!

"PostSharp simplicity is simply amazing."

PostSharp rocks! And I mean that as someone who is doing AOP for a long while, and has implemented some not insignificant parts of Castle.DynamicProxy. Leaving aside the amount of power that it gives you, PostSharp simplicity is simply amazing, wow!

"It has reduced thousands of lines of code."

PostSharp was especially good when we had to embed applications and needed to transfer data between them. We would have had to write a lot of code if not for just one aspect and now we don’t even think about it. It’s made life a lot easier from a development point of view.

"PostSharp is very easy to use."

Releasing developers from writing boilerplate or infrastructure code helps my team to complete features faster. We definitely save coding time with PostSharp. We’re relieved from writing INotifyPropertyChanged and creating ICommand properties needed for data binding.
