Soap WebService Server with .NET6 and XML attributes

I'm migrating a .NET Framework SOAP Web Service (Server Side) to a new .NET 6 project.
I used DataContract and DataMember with no issues until I reached a WS which had to return XML attributes.
Then I read the official documentation but was not able to find a way to return attributes inside my XML elements.
They suggest to use XmlSerializer and the "XmlAttribute" attributes, but they seems to be ignored by .NET 6.
Am I forced to roll it back to .NET Framework or is there anything I can do?
Here is a simple example that's not working:
Of course if I switch it back to DataModel it works, but I am not able to have XML attributes.
What I want to achieve is
<BankingTransaction operation="opName">
<amount>100</amount>
</BankingTransaction>
THE INTERFACE
[ServiceContract]
[XmlSerializerFormat]
public interface IBankingService
{
[OperationContract]
public BankingTransaction ProcessTransaction();
}
THE SERVICE IMPLEMENTATION
public class BankingService: IBankingService
{
public BankingTransaction ProcessTransaction()
{
BankingTransaction bt = new BankingTransaction();
bt.amount = 1000;
bt.Operation = "Test";
return bt;
}
}
THE MODEL
public class BankingTransaction
{
[XmlAttribute]
public string Operation;
[XmlElement]
public int amount;
}
Thanks
A PIECE OF THE program.cs file
builder.Services.TryAddSingleton<IBankingService, BankingService>();
app.UseSoapEndpoint<IBankingService>("/Service.asmx", new SoapEncoderOptions());

Json.Net serialize/deserialize Class Name attribute C#

Sorry for the (maybe) trivial question but, I'm trying to consume a web service where the entities and my data model classes are named different.
I want to keep my model .Net Class name and use a Json Attribute name to map, serializer/deserializer, with the corresponding web service entity.
For example:
Web Service Entity:
"People"
My Model Class:
"Employee"
What I've already do:
[JsonObject(Title="People")]
public class Employee
{
[JsonProperty("DifferentPropertyName")]
string propertyName1 { get; set; }
}
But the json serializer/Deserializer continues to use the .Net class name and I need to set the jsonObject Title.
There is a way to achieve it?
EDIT
I'm working on a Xamarin Forms app, using Simple.OData.Client to consume an OData Service
Thanks

DataContractAttribute may be your solution.
public class RichFilter
{
public Trolo item { get; set; }
}
[DataContract(Name = "item")]
public class Trolo
{
public string connector { get; set; }
}
If you serialize a RichFilter object, here is the output :
{"item":{"connector":"AND"}}

WCF Webservice not seeing parameter

I have a WCF webservice that validates XML data using a file path as a parameter. However when I call it it totally ignores the parameter.
Webservice:
namespace MyApp.Validation.WebServices
{
public class ValidateSurveyData : IValidateSurveyData
{
private ValidateSurveyDataResponse response = new ValidateSurveyDataResponse();
public ValidateSurveyDataResponse ValidateXMLSurveyData(string XMLFile)
{
//Validation Code
return response;
}
}
}
Interface:
namespace MyApp.Validation.WebServices
{
[ServiceContract]
public interface IValidateSurveyData
{
[OperationContract]
ValidateSurveyDataResponse ValidateXMLSurveyData(string XMLFile);
}
[DataContract]
public class ValidateSurveyDataResponse
{
[DataMember]
[Description("XML Data Validation Errors")]
public List<SurveyValidationError> DataValidationErrors { get; set; }
public ValidateSurveyDataResponse()
{
DataValidationErrors = new List<SurveyValidationError>();
}
}
}
In the Test Client:
When I debug the code XMLFile is always null. In desperation I have tried C:\MyFile.xml, #C:\MyFile.xml, #"C:\MyFile.xml", "C:\MyFile.xml" as parameters but I always get the same, XMLFile is null. What am I missing?
Update
Ok feeling slightly embarrassed! the problem was not with the service at all its with the data I am passing. C:\XmlFile.xml give a null parameter but C:\\XmlFile.xml gives correct results.

I think you are missing the parameter in ValidateSurveyDataResponse() method, the signature should be like this
public ValidateSurveyDataResponse(string XMLFile)

add following line above ValidateXMLSurveyData function in Interface.
[WebInvoke(Method = "POST", UriTemplate = "ValidateXMLSurveyData?value={XMLFile}")]
sample call
http://localhost:5647/ValidateSurveyData.svc/ValidateXMLSurveyData?value="C:\MyFile.xml"

How to create a URI template in WCF?

I'm new to wcf services development. I have the following problem:
I'm creating wcf-service with URI template like this:
[OperationContract, WebGet(UriTemplate = "/EmpDetails/command/?command=SaveDetails&id={id}&data{empid:{EmpID},EmpName:{EmpName},EmpAge:{EmpAge}}"
How can I access these values to save details?
another thing is i want this URL to be used to save details.
http://12.154.21.23:8888/EmpDetails/command/?command=SaveDetails&data={empid:Test,EmpName:TestName,EmpAge:26}

You need to create a class somewhere in service:
[DataContract]
public class Data
{
[DataMember]
public int EmpID {get;set;}
[DataMember]
public string EmpName{get;set;}
[DataMember]
public string EmpAge {get;set;}
}
Next, add this to your wcf service interface:
[OperationContract]
[WebGet(UriTemplate = "/EmpDetails/command/?command=SaveDetails&id={id}&data{EmpID:{EmpID},EmpName:{EmpName},EmpAge:{EmpAge}}")]
void SaveDetails(int id, Data data);
and finally, add code below to class implementing wcf service interface:
public void SaveDetails(int id, Data data)
{
//do smt
}

WCF REST Starter Kit not filling base class members on POST

I have a WCF REST Starter Kit service. The type handled by the service is a subclass of a base class. For POST requests, the base class members are not correctly populated.
The class hierarchy looks like this:
[DataContract]
public class BaseTreeItem
{
[DataMember]
public String Id { get; set; }
[DataMember]
public String Description { get; set; }
}
[DataContract]
public class Discipline : BaseTreeItem
{
...
}
The service definition looks like:
[WebHelp(Comment = "Retrieve a Discipline")]
[WebGet(UriTemplate = "discipline?id={id}")]
[OperationContract]
public Discipline getDiscipline(String id)
{
...
}
[WebHelp(Comment = "Create/Update/Delete a Discipline")]
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "discipline")]
public WCF_Result DisciplineMaintenance(Discipline discipline)
{
...
}
Problem: While the GET works fine (returns the base class Id and Description), the POST does not populate Id and Description even though the XML contains the fields.
Sample XML:
<?xml version="1.0" encoding="utf-8"?>
<Discipline xmlns="http://schemas.datacontract.org/2004/07/xxx.yyy.zzz">
<DeleteFlag>7</DeleteFlag>
<Description>2</Description>
<Id>5</Id>
<DisciplineName>1</DisciplineName>
<DisciplineOwnerId>4</DisciplineOwnerId>
<DisciplineOwnerLoginName>3</DisciplineOwnerLoginName>
</Discipline>
Thanks for any assistance.

I could not solve the problem using a DataContractSerializer. I switched to using the XMLSerializerFormat and everything worked fine. In fact, the capabilities of the XMLSerializer are so much better that for purely XML work, it is probably better to use the XMLSerializer in all cases.
