It seems like forever that I have wanted to create an application that I can use to track all the training rides I do while cycling.  Although I don't race that much anymore, I still ride about every day and do various workouts.  I figure that I will start building the app with Windows Forms and then possibly utilize a web service later on to share data with other people that I train with.  One of the first things I wanted to do was to save various user settings between sessions of the application.  Things like the size of the WinForm, last used file, etc.  I did some research this morning and found some good API documentation and information on MSDN and a great tutorial at DevCity.Net.  Within a short time I had a sample application up an running that saves an XML file into my windows profile local settings location on a Windows XP box:

C:\Documents and Settings\<username>\Local Settings\Application Data\IsolatedStorage

This was so easy to do with the .NET Framework libraries and the tutorial from DevCity.  I am on my way, at least for now....
