Cross. Cutter. N A Light Weight AOP Tool for.NETIntroduction.As AOP has become a well known and exercised concept in programming, developers have become more and more dependent on proper AOP tools.In.NET programming, the best known AOP tool would be Post.Sharp, which allows injection of custom AOP code using custom attributes.As good things always dont come free, besides some troublesome manual certificate acquiring process, Post.Sharp express version also has limitations which makes developers who concern about their project scale hesitate to use it, and the price of ultimate version would become a major concern of quite some developers.To have a free AOP tool for.NET, Cross.Cutter.N is implemented.It provides AOP functionalities, and works a bit differently than most existing AOP tools.The advantages of Cross.Modes.png' alt='Wpf Binding Target Not Updated Yet' title='Wpf Binding Target Not Updated Yet' />Catch up on the questions we couldnt answer live, and learn more about the latest features in Kendo UI for jQuery and Kendo UI for Angular.This article summarizes key new features and improvements in the following versions of the.NET Framework.NET Framework 4.NET Framework 4.Cutter. N tool include Free Cross.Cutter.N is open source and free under MIT license.Light Weight Instead of adding compile time dependency to projects, Cross.Cutter.N injects AOP code at post build stage.This approach allows AOP code injection into assemblies whose source code is not available, and decouples project code from AOP code as much as possible.Cross Platform Cross.Cutter.N works in both.Out of the box aspect switching support Cross.Cutter.N allows users to switch onoff AOP code that is injected to methodsproperties during project run time at multiple granularity levels.Designed for optimized performance Cross.Cutter.N uses IL weaving technology to make the injected AOP code work as efficient as directly coded in target projects, and the implementation is optimized to avoid unnecessary local variable initializations and method calls.Background.This article assumes that readers are familiar with the concept of Aspect Oriented Programming, and perhaps have some previous experience using AOP frameworks like Post.Sharp, Spring AOP and so on.Wpf Binding Target Not Updated Yet' title='Wpf Binding Target Not Updated Yet' />Examples.To perform weave AOP code into an assembly, Cross.Cutter.N requires the following process Prepare the AOP code module following Cross.Cutter.N convention.The AOP code content is fully customizable by developers.Prepare the configuration file for the AOP module.Prepare the configuration file for the target module, which requires the AOP code to be injected to.Execute console application tool to weave the original assembly together with the AOP code information into a new assembly.Then its done.Lets take a very simple C method for example namespace Cross.Cutter.N. Sample.Target.System.Target. publicstaticint Addint x, int y.Console.Out. Write.LineAdd starting.Console.Out. Write.LineAdd ending.When executed, the output to console would be Now what if I want to inject some AOP code to the Add method For example, to log the function call and all its parameter values upon entering the method call, and the return value before the method returns Cross.Cutter.N currently provides 2 ways to do so.Before executing console application tool in each of the the examples, please make sure to rebuild the sample target project, to get a fresh target assembly for Cross.Cutter.N to perform IL weaving to.Using Name of Methods to Find Target Methods to Be Injected.By following the steps listed Implement AOP Module.Implement some utility properties and methods first namespace Cross.Cutter.N.

This reference is implemented and provided by Cross.Cutter.N tool which will find methods to inject AOP code into by checking the methods names.This aspect builder will inject all methods whose full name is like Cross.Cutter.N.

Name in configuration for ordering and C code to switch onoff.One assembly is in the Targets assemblies to be injected.The assembly is Cross.Cutter.N. Sample.Target.Its not an absolute path, so the path is relevant to the configuration file, in this case its in the same folder of the configuration file.The weaved assembly will be saved as Cross.Cutter.N. Sample.Target.The file name of the output assembly is exactly the same with the target assembly, so the original assembly will be overwritten by the weaved one.Please note that exe is for.It should be Cross.Cutter.
