CommonApplicationData on Vista

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I have an app that uses Embedded Firebird for its DB so that I don't need to
install a DB server. On Vista my app throws an exception "Error trying to
write to file (the correct path here)".

The following code proves that the current user is able to write to the
specified folder.

static void Main(string[] args)
{
string fileName =
Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData);
fileName = Path.Combine(fileName, "MyTest.txt");
Console.WriteLine("Writing to " + fileName);
StreamWriter sw = new StreamWriter(fileName);
using (sw)
sw.WriteLine("Hello");
Console.WriteLine("Done");
Console.ReadLine();
}


I have checked and the database file is in CommonApplicationData.


So my question is, are the UAC rules different between .NET assemblies and
binaries? It's the only thing I can think of :-)
