System.IO.DirectoryNotFoundException after deleting an empty folder and recreating it

Question

I want to copy a folder, and i want to delete destination folder first. So I am deleting destination folder then recreate it and then copy files. The problem is that i get the <

Ok This is very strange. the exception only happen when the destination folder is empty. but adding the folowing line after the destination folder deletion seem to solve the problem. the line : MessageBox.Show("folder " + destFolder + "folder was deleted", "alert");

static public void CopyFolder(string sourceFolder, string destFolder)
    {
        if (Directory.Exists(destFolder)) // check if folder exist
        {
            Directory.Delete(destFolder, true);  // delete folder
            MessageBox.Show("folder " + destFolder + "folder was deleted", "alert");
        }
        Directory.CreateDirectory(destFolder); // create folder

        string[] files = Directory.GetFiles(sourceFolder);
        foreach (string file in files)
        {
            string name = Path.GetFileName(file);
            string dest = Path.Combine(destFolder, name);
            File.Copy(file, dest, true);
            FileInfo fileinfo = new FileInfo(dest); // get file attrib
            if (fileinfo.Attributes != FileAttributes.ReadOnly) // check if read only 
                File.SetAttributes(dest, FileAttributes.Normal);
        }

so putting a MessageBox.show after the deletion causes the System.IO.DirectoryNotFoundException to go away. its as if the fact that there is a small delay after the deletion , the recreation of the folder goes well. i guess i will find a work around this, but if someone knows what is causing this and the way to solve it , i will be very happy to hear it.
