Adds multi feature enhancements to your visual studio environment:
GhostDoc is a Visual Studio extension that automatically generates XML documentation comments for methods and properties based on their type, parameters, name, and other contextual information. When generating documentation for class derived from a base class or for interface implementation (e.g. .NET Framework or your custom framework), GhostDoc will use the documentation that Microsoft or the framework vendor has already written for the base class or interface.
NuGet is the package manager for the Microsoft development platform including .NET. The NuGet client tools provide the ability to produce and consume packages.
AnkhSVN is a Subversion SourceControl provider for Visual Studio. The software allows you to perform the most common version control operations directly from inside the Microsoft Visual Studio IDE. With AnkhSVN you no longer need to leave your IDE to perform tasks like viewing the status of your source code, updating your Subversion working copy and committing changes. You can even browse your repository and you can plug-in your favourite diff tool.
Adds a right-click menu to any folder and image in Solution Explorer that lets you automatically optimize all PNG, GIF and JPEG files in that folder. The optimisation doesn't affect the quality of the images, but optimises them using industry proven algorithms for removing EXIF and other metadata.
