XmlBinaryReader.ReadElementContentAsDouble() is not working for double.NaN which is throwing an exception in .net7 The input source is not correctly formatted.. But which is working fine in .net6.
We are using CoreWCF and we are trying to send double.NaN as a parameter. Samething we are getting the below exception .net7
System.ServiceModel.FaultException: 'The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'NanTest'. The input source is not correctly formatted.'. But which is working fine in .net6
Reproduction Steps
Run the below code
var message = System.ServiceModel.Channels.Message.CreateMessage(System.ServiceModel.Channels.MessageVersion.Default,
"http://tempuri.org/IHelpServ/NanTest",
double.NaN);
var reader = message.GetReaderAtBodyContents();
double value = reader.ReadElementContentAsDouble();Expected behavior
It should deserialize the content as double
Actual behavior
throwing an exception in .net7 The input source is not correctly formatted.
Regression?
working fine in .net 6
