ASP.NET Core 6中SOAP端点配置问题咨询

问题背景与疑问 #

之前只开发过REST接口，都是直接在Controller中通过特性配置端点，示例如下：

[HttpGet("someEndpoint")]

现在需要开发SOAP接口，尝试在Program.cs中配置端点，但调用BasicHttpBinding()时一直报错。想咨询：是否需要像配置REST API那样在Controller中设置SOAP端点？

（注：母语为德语，英文表述欠佳，请见谅）

附报错截图：

初始配置代码 #

using SoapCore;
using System.ServiceModel;
using WebAPI_2023.Models;
using WebAPI_2023.Services;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddSoapCore();
builder.Services.AddScoped<CalculatorService>();
builder.Services.AddSingleton<ISampleService, SampleService>();
builder.Services.AddControllers();

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

app.UseSoapEndpoint<ISampleService>("/Service.asmx", new 
BasicHttpBinding(), SoapSerializer.XmlSerializer);

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();

app.Run();

问题解决 #

已找到错误，现在运行正常，修改后的配置代码如下：

app.UseEndpoints(endpoints =>
{
    endpoints.UseSoapEndpoint<ISampleService>("/Service.asmx", new 
    SoapEncoderOptions(), SoapSerializer.XmlSerializer);
});
