I came across an excellent run down of the limitation of System.Gadget.Settings for those who are writing gadgets for Windows Vista. Instead of recapping the article, I will simply point to it here. The author provides a settings management class to replace the one that is used by default, allowing one to get around the maximum string length for a setting of 2048. I plan on using this class in the development of my gadgets to store JSON for settings to make the code more concise and straight forward.
