Trying to open a file dialog but I get an exception when calling ShowDialog. This pice of code have always worked fine but I think when I upgrade to Silverlight 4 it caused some problem.

Code:

var dlg = new OpenFileDialog { Filter = "CSV Files (*.csv)|*.csv" }; 

if (dlg.ShowDialog() == true)

{
    Upload(dlg.File);
}

Exception:

Directory = 'dlg.File.Directory' threw an exception of type 'System.Security.SecurityException'
{System.Security.SecurityException: File operation not permitted. Access to path file.csv' is denied.
   at System.IO.FileSecurityState.EnsureState()
   at System.IO.FileInfo.get_DirectoryName()
   at System.IO.FileInfo.get_Directory()
}

It seems like it´s problem to get options for the directory because I got correct filename and file size but no information about the directory and directory name.

If you are trying to debug the application then you will get this security exception. Try to run without debugging and check if you are still getting this error.
