A buried fact is how to manage IsolatedStorage -- you don't see it mentioned too often.

Just use the StoreAdm command line tool, which provides a couple of ways to cleanup after a person.

You'll probably find the *.exe here:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\StoreAdm.exe

or

c:\program files\microsoft visual studio 8\sdk\v2.0\bin\storeadm.exe

This is more of a reminder to myself than anything else, but I'm *always* looking high and low for this in the wrong place (I keep on reaching for System.IO.Directory when in fact its under System.Environment):

Environment.GetFolderPath(
    System.Environment.SpecialFolder.CommonApplicationData);

Environment.GetFolderPath(
    System.Environment.SpecialFolder.ApplicationData);

etc.

Basic File operations on the .NET platform are really easy, once you get past the one or two strangely chosen class names.

This is a post demonstrating various ways of getting the job done, depending on how much control you need.

I was just writing up in another post about the System.IO.File in terms of streams, when I realized that this section could come in handy, as a quick reference, in the future, and deserved its own post.

It just lists, succinctly, the most common static methods used to open, read, write files, with information as to the returned variable, Encoding used, and whether an err if will be thrown if the file is not found...
