Vista - DataContract with DateTime field gives error

Hi all,

I try to get my fingers around the Hands-On Labs for WCF.
One of the samples uses the following DataContract:

[DataContract(NameSpace="Fabrikam", Name="Trade")]
public class Trade
{
[DataMember]
public string Symbol;
[DataMember]
public long? Count;
[DataMember]
public DateTime? Date;
}

The Service contract has the following Operation:

void AddTrade(Trade trade);

While implementing the functionality and setting the ServiceBehaviour
of the service implementation to (ReturnUnknownExceptionsAsFaults =
true) results in the following error:

System.ServiceModel.UnknownFaultException: The added or subtracted
value results in an un-representable DateTime.

Does anyone has an idea about the cause?

I have the WinFX Jan CTP.

Thanks in advanche,
Iwan Bel

Iwan,

instead of "DateTime.Now" you should use :

new DateTime(
DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day,
DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second,
DateTime.Now.Millisecond);

or more simply:

new DateTime(DateTime.Now.Ticks);
