Tried to decorate my button event handler thus
[IsolatedStorageFilePermission(SecurityAction.Assert)]
private void button1_Click(object sender, EventArgs e)
{
listBox1.Items.Add("GetMachineStoreForApplication : " +
IsolatedStorageFile.GetMachineStoreForApplication());
listBox1.Items.Add("GetMachineStoreForAssembly : " +
IsolatedStorageFile.GetMachineStoreForAssembly());
listBox1.Items.Add("GetMachineStoreForDomain : " +
IsolatedStorageFile.GetMachineStoreForDomain());
listBox1.Items.Add("GetUserStoreForApplication : " +
IsolatedStorageFile.GetUserStoreForApplication());
listBox1.Items.Add("GetUserStoreForAssembly : " +
IsolatedStorageFile.GetUserStoreForAssembly());
listBox1.Items.Add("GetUserStoreForDomain : " +
IsolatedStorageFile.GetUserStoreForDomain());
}
No deal. Still get the exception. Use of either SecurityAction.Assert or
SecurityAction.Demand makes no difference.
I tried to establish FullTrust at the assembly level
[assembly: PermissionSetAttribute(SecurityAction.RequestMinimum, Name =
"FullTrust")]
Still no dice.
Why does something that should be simple have to be made so hard??

Subject: Isolated Storage Security
Currently using XP Pro as our SOE. Will be moving to Win 7 with PC fleet
replacement.
I want to write my applications so that I can persist application/assembly
settings and also user settings so it will run with Win 7.
This is probably really old ground for most so I apologise for bringing
something up that has probably been dealt to death previously.
I have written a really basic application to discover where these are. I am
just adding the possible locations to a listbox.
listBox1.Items.Add("GetMachineStoreForApplication : " +
IsolatedStorageFile.GetMachineStoreForApplication());
listBox1.Items.Add("GetMachineStoreForAssembly : " +
IsolatedStorageFile.GetMachineStoreForAssembly());
listBox1.Items.Add("GetMachineStoreForDomain : " +
IsolatedStorageFile.GetMachineStoreForDomain());
listBox1.Items.Add("GetUserStoreForApplication : " +
IsolatedStorageFile.GetUserStoreForApplication());
listBox1.Items.Add("GetUserStoreForAssembly : " +
IsolatedStorageFile.GetUserStoreForAssembly());
listBox1.Items.Add("GetUserStoreForDomain : " +
IsolatedStorageFile.GetUserStoreForDomain());
It bombs on the first line with a IsolatedStorageException "Unable to determine
application identity of the caller."

What does one do to get it to work? Strongly name it? Does one have to take
some action so that it will work when one is developing and then another after
one has deployed it.
I tried this in the form load event
public Form1()
{
InitializeComponent();
IsolatedStorageFilePermission isfp = new
IsolatedStorageFilePermission(PermissionState.Unrestricted);
isfp.Assert();
}
But this does nothing.
