+Summary: User operators are ignored for implicit conversions
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+We are missing probing for user operators.
+
+
+Steps to reproduce the problem:
+1. 
+
+using System;
+
+class A
+{
+	public static implicit operator sbyte (A mask)
+	{
+		return 1;
+	}
+
+	public static implicit operator byte (A mask)
+	{
+		return 2;
+	}
+	
+	public static implicit operator short (A mask)
+	{
+		return 3;
+	}
+
+	public static implicit operator ushort (A mask)
+	{
+		return 4;
+	}
+	
+	public static implicit operator int (A mask)
+	{
+		return 5;
+	}
+
+	public static implicit operator uint (A mask)
+	{
+		return 6;
+	}
+	
+	public static implicit operator long (A mask)
+	{
+		return 7;
+	}
+
+	public static implicit operator ulong (A mask)
+	{
+		return 8;
+	}
+}
+
+class A2
+{
+	public static implicit operator sbyte (A2 mask)
+	{
+		return 1;
+	}
+
+	public static implicit operator byte (A2 mask)
+	{
+		return 2;
+	}
+	
+	public static implicit operator short (A2 mask)
+	{
+		return 3;
+	}
+
+	public static implicit operator uint (A2 mask)
+	{
+		return 6;
+	}
+	
+	public static implicit operator long (A2 mask)
+	{
+		return 7;
+	}
+
+	public static implicit operator ulong (A2 mask)
+	{
+		return 8;
+	}
+}
+
+class A3
+{
+	public static implicit operator sbyte (A3 mask)
+	{
+		return 1;
+	}
+
+	public static implicit operator uint (A3 mask)
+	{
+		return 6;
+	}
+	
+	public static implicit operator long (A3 mask)
+	{
+		return 7;
+	}
+
+	public static implicit operator ulong (A3 mask)
+	{
+		return 8;
+	}
+}
+
+class A4
+{
+	public static implicit operator uint (A4 mask)
+	{
+		return 6;
+	}
+	
+	public static implicit operator long (A4 mask)
+	{
+		return 7;
+	}
+
+	public static implicit operator ulong (A4 mask)
+	{
+		return 8;
+	}
+}
+
+class A5
+{
+	public static implicit operator uint (A5 mask)
+	{
+		return 6;
+	}
+
+	public static implicit operator ulong (A5 mask)
+	{
+		return 8;
+	}
+}
+
+class A6
+{
+	public static implicit operator byte (A6 mask)
+	{
+		return 2;
+	}
+}
+
+
+public class Constraint
+{
+	public static int Main ()
+	{
+		A a = null;
+		A2 a2 = null;
+		A3 a3 = null;
+		A4 a4 = null;
+		A5 a5 = null;
+		A6 a6 = null;
+		
+		Console.WriteLine (-a);
+		Console.WriteLine (-a2);
+		Console.WriteLine (-a3);
+		Console.WriteLine (-a4);
+		Console.WriteLine (-a5);
+		Console.WriteLine (-a6);
+		
+		Console.WriteLine (~a);
+		Console.WriteLine (~a2);
+		Console.WriteLine (~a3);
+		Console.WriteLine (~a4);
+		Console.WriteLine (~a5);
+		Console.WriteLine (~a6);
+		return 0;
+	}
+	
+}
+
+Actual Results:
+
+test-op.cs(156,36): error CS0023: The `-' operator cannot be applied to
+operand of type `A4'
+test-op.cs(157,36): error CS0023: The `-' operator cannot be applied to
+operand of type `A5'
+test-op.cs(163,36): error CS0023: The `~' operator cannot be applied to
+operand of type `A4'
+test-op.cs(164,36): error CS0023: The `~' operator cannot be applied to
+operand of type `A5'
+
+
+Expected Results:
+
+The program should compile and run producing following output.
