           Summary: SOAP serialization exception when remoting
                    TimeSpan.MinValue
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.4.x
          Platform: 64bit
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: System
        AssignedTo: mono-bugs at lists.ximian.com

System.Runtime.Remoting.Metadata.W3cXsd2001.SoapDuration.ToString() throws a
System.OverflowException when I try to pass TimeSpan.MinValue to a remote
method invocation.  This is because the code calls TimeSpan.Negate(), which is
supposed to throw the exception for TimeSpan.MinValue.  (So TimeSpan.Negate()
is doing the right thing - SoapDuration.ToString() is not.)

Reproducible: Always

Steps to Reproduce:
1. Run "csharp" to bring up the C# REPL
2. Enter this:

System.Runtime.Remoting.Metadata.W3cXsd2001.SoapDuration.ToString
(TimeSpan.MinValue);

Actual Results:  
System.OverflowException: This TimeSpan value is MinValue and cannot be
negated.
  at System.TimeSpan.Negate () [0x00000] 
  at System.Runtime.Remoting.Metadata.W3cXsd2001.SoapDuration.ToString
(TimeSpan timeSpan) [0x00000] 
  at Class1.Host (System.Object& $retval) [0x00000] 
  at Mono.CSharp.Evaluator.Evaluate (System.String input, System.Object&
result, System.Boolean& result_set) [0x00000] 
  at Mono.CSharpShell.Evaluate (System.String input) [0x00000] 


Expected Results:  
"-P10675199DT2H48M5.4770000S"

(I think this is right - what really matters, though, is that it deserializes
back to TimeSpan.MinValue.)
