SoapCore .Net6.0 error Incorrect Content-Type: text/xml; charset=UTF-8 - wcf

Question

i m having a problem with SoapCore.
The library i m using is https://github.com/DigDes/SoapCore, i have to migrate code from WCF service, i can make WCF endpoint but the JS client of the service get the error:
System.InvalidOperationException: Incorrect Content-Type: text/xml; charset=UTF-8
This is the program.cs:
builder.Services.AddControllers().AddXmlSerializerFormatters().AddXmlDataContractSerializerFormatters();
builder.Services.AddSoapCore();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddSingleton<IWebAvisos, RemoteControlService>();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI();
}
app.UseRouting();
app.UseHttpsRedirection();
app.UseEndpoints(endpoints => {
var encodes = new SoapEncoderOptions();
endpoints.UseSoapEndpoint<IWebAvisos>("/ServicioAvisos/WebAvisos", encodes, SoapSerializer.XmlSerializer) ;
});
app.UseRouting();
app.UseAuthorization();
app.Run();
Interface:
[ServiceContract]
public interface IWebAvisos
{
[OperationContract]
List<string> GetRemoteControl(int Id);
}
Class:
public class RemoteControlService : IWebAvisos
{
public RemoteControlService()
{
}
public List<string> GetRemoteControl([FromBody] int ObjId)
{
return new List<string>()
{
"1",
"2"
};
}
}
as you can see is a dummy example and has to work with POST Xmlhttprequest from javascript since we have several clients and we need to be compatible with them:
This is the way i have to make the request and the server answer:
URL --> /ServicioAvisos/WebAvisos/GetRemoteControl
BODY --> <GetRemoteControl xmlns="http://tempuri.org/"><Id>0</Id></GetRemoteControl>
Headers -->
Content-Type:text/xml; charset=UTF-8
X-Requested-With:XMLHttpRequest
any help would be appreciated.
