.NET ResourceExplorer
In writing the resources chapter of my WinForms book, I found that there was no single utility for displaying the resource contents of assemblies, .resx files and .resource files (even embedded .resources files) in a way that made sense to me. So, I built one and called it ResourceExplorer.
ResourceExplorer is very simple and could stand some extension to show specific resources at images, text, data, etc, but it certainly served my needs, especially when it came to understanding the usage and limitations of the ResourceReader (for reading .resources files) and the ResXResourceReader (for reading .resx files). Enjoy.
