Publish SOAP web service in .NET Core 6.0 to IIS

I have seen several tutorials on how to publish a SOAP service made in .NET Core 6.0 in an IIS but I can't get it to work.

This is the configuration:

From the execution of the project in Visual Studio it opens without problems: localhost:1234/Service.asmx but when launching the publication to an IIS of another computer I can't get it to respond to the address: http://LOCALHOST:1819/Service.asmx

Can someone give me some information to correctly configure publishing to an IIS? Give me some advice or give me some tutorial?

Thank you so much

I have tried several configurations and in no case have I been able to get the service to respond to me.

For another person:

This tutorial explained how to create, configure, and deploy a SOAP service using .NET Core 6.0 and the SOAPCore package. The main steps included:

Creating a new .NET Core 6.0 project. (ASP NET CORE Web API)

Installing the SOAPCore NuGet package.

Implementing a SOAP service contract (interface) and the corresponding service implementation.

Configuring the service in the Program.cs file. Example:

using SoapCore;
using SOAP_CORE_V1.Service;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers();
builder.Services.AddSoapCore();
builder.Services.AddSingleton<IService, Service>();

var app = builder.Build();

// Configura el middleware
if (app.Environment.IsDevelopment()) {
  app.UseDeveloperExceptionPage();
}

app.UseRouting(); // Asegúrate de que esta línea esté presente

app.UseEndpoints(endpoints => {
  endpoints.MapControllers();
  app.UseSoapEndpoint<IService>("/SOAP_CORE_V1.asmx", new SoapEncoderOptions());
});

app.Run();

Debugging and running the service in a development environment using IIS Express and Visual Studio. EXAMPLE:

http://LOCALHOST:12345/SOAP_CORE_V1.asmx

Publish the application using dotnet publish or Visual Studio.

Install the ASP.NET Core module on the IIS server

Create a new website or application in IIS, pointing to the published output folder.

Configure the web.config file for the production environment.
Set the ASPNETCORE_ENVIRONMENT variable to "Production" in the web.config file. EXAMPLE:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\SOAP_CORE_V1.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" >
        <environmentVariables>
          <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
        </environmentVariables>
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

After following these steps, the SOAP service should be running and accessible in : HTTP://ip:port/SOAP_CORE_V1.asmx
