How do I overload method parameter using NET5 SoapCore - asp.net-core

Question

I'm trying to port an existing Soap WebService to .NET5 but am having issue with overloading a Soap method parameter.
In NET4 the code looks like this
namespace SoapWebServiceeTest.Soap
{
/// <summary>
/// Summary description for WsgSPServiceOrderService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class TextWebService : System.Web.Services.WebService
{
[WebMethod]
public string Test(
[XmlElement("object1", typeof(Object1))]
[XmlElement("object2", typeof(Object2))]
[XmlElement("object3", typeof(Object3))]
object request)
{
return $"{request.GetType().Name}";
}
}
public class Object1 { public string Param1 { get; set; } }
public class Object2 { public string Param2 { get; set; } }
public class Object3 { public string Param3 { get; set; } }
}
How do I achieve this in .NET5?
I have tried following but got reflection exception: System.Reflection.AmbiguousMatchException: 'Multiple custom attributes of the same type found.'
[ServiceContract]
public interface ITestWebService
{
[OperationContract]
string Test(
[XmlElement("object1", typeof(Object1))]
[XmlElement("object2", typeof(Object2))]
[XmlElement("object3", typeof(Object3))]
object request);
}
And also tried this but VS Add Connected Services errored with "More than one message named 'ISampleService_Test_InputMessage' was specified. Each message must have a unique name."
[OperationContract]
string Test(Object1 request);
[OperationContract]
string Test(Object2 request);
Any help would be awesome

You may try this
You can make it post or get based on your need
[OperationContract]
[WebInvoke(UriTemplate = "Test1", Method = "POST"]
string Test(Object1 request);
and
[OperationContract]
[WebInvoke(UriTemplate = "Test2", Method = "POST"]
string Test(Object2 request);
This way you can achieve objective
