+Summary: FileShare.Delete not accepted by System.IO.FileStream ctor
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+FileStream..ctor performs this suspicious check:
+
+      if ((share < FileShare.None) || (share > FileShare.ReadWrite))
+      {
+            throw new ArgumentOutOfRangeException("share", "Enum value was
+out of legal range.");
+      }
+ 
+FileShare.Delete happens to have the value 4, which is unfortunately
+FileShare.ReadWrite (= 3) :)
+
+Steps to reproduce the problem:
+
+using System;
+using System.IO;
+
+namespace ConsoleApplication1
+{
+	class Program
+	{
+		static void Main(string[] args)
+		{
+			Stream s = new FileStream(
+					@"C:\Temp\test",
+					FileMode.Open,
+					FileAccess.Read,
+					FileShare.ReadWrite | FileShare.Delete);
+		}
+	}
+}
+
+
+Actual Results:
+Unhandled Exception: System.ArgumentOutOfRangeException: Enum value was out
+of legal range.
+Parameter name: share
+
+Expected Results:
+-
+
+How often does this happen? 
+Always.
