Summary: System.Web.Extensions JSON deserialization does not
support nullable value types
Classification: Mono
Product: Mono: Class Libraries
Version: 2.8.x
Platform: i686
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Sys.Web
AssignedTo: mhabersack at novell.com

Description of Problem:
The DataContractJsonSerializer is filling nullable value types with 0 instead
of the true value even when a value is provided. I would expect the nullable
value type to default to null if not provided within the stream else be set to
value provided by the stream.
Steps to reproduce the problem:
1.
[DataContract]
public class c
{
public c() { }
[DataMember]
public int? parm_id { get; set; }
[DataMember]
public decimal? val { get; set; }
}
2.
string js = "{\"parm_id\":2}";
Use DataContractJsonSerializer to fill an instance with js.
Actual Results:
parm_id contains 0.
val contains 0
Expected Results:
parm_id should contain 2.
val should contain null.
How often does this happen?
Everytime.
Additional Information:
Native windows returns expected results.
