+Summary: FileShare Enumeration is not implemented by Mono
+
+The following code snippet (from msdn) shows that mono does not yet
+implement  FileShare.None correctly. (The library seems to have the enum at
+least :)
+
+/* EXAMPLE */
+
+using System;
+using System.IO;
+                                                                          
+                                                                    
+public class OpenTest
+{
+    public static void Main()
+    {
+        // Open an existing file, or create a new one.
+        FileInfo fi = new FileInfo("temp.txt");
+                                                                          
+                                                                    
+        // Open the file just specified such that no one else can use it.
+        FileStream fs = fi.Open( FileMode.OpenOrCreate,
+FileAccess.ReadWrite, FileShare.None );
+                                                                          
+                                                                    
+        // Create another reference to the same file.
+        FileInfo nextfi = new FileInfo("temp.txt");
+                                                                          
+                                                                    
+        try
+        {
+            // Try opening the same file, which was locked by the previous
+process.
+            nextfi.Open( FileMode.OpenOrCreate, FileAccess.Read );
+                                                                          
+                                                                    
+            Console.WriteLine("The file was not locked, and was opened by a
+second process.");
+        }
+        catch (IOException)
+        {
+            Console.WriteLine("The file could not be opened because it was
+locked by another process.");
+        }
+        catch (Exception e)
+        {
+            Console.WriteLine(e.ToString());
+        }
+                                                                          
+                                                                    
+        // Close the file so it can be deleted.
+        fs.Close();
+    }
+}
+
+/* END EXAMPLE */
+
+At the moment, latest mono cvs (2003-07-09) gives this:
+The file was not locked, and was opened by a second process.
