.NET Reflector enables you to easily view, navigate, and search through the class hierarchies of .NET assemblies, even if you don't have the code for them. With it, you can decompile and analyze .NET assemblies in C#, Visual Basic, and IL.

With .NET Reflector Pro, you'll get the latest version of .NET Reflector, plus a Visual Studio add-in with the Pro features.

.NET Reflector Pro integrates .NET Reflector into Visual Studio to allow you to seamlessly debug into third-party code and assemblies, even if you don't have the source code for them. You can now treat decompiled assemblies much like your own code: you can step through the assemblies and use all the debugging techniques that you would use on your own code.
