由于未看到 AddSwaggerGen，发布到 Azure 失败

Question

我有一个简单的 ASP.NET Core 3.1 应用程序，我正在尝试将其发布到 Azure。

但是发布失败并出现以下错误：

Publish has encountered an error. Be sure that the Startup.cs for your application is calling AddSwaggerGen from within ConfigureServices in order to generate swagger file. Visit https://go.microsoft.com/fwlink/?LinkId=2131205&CLCID=0x409 for more information.

但它配置正确并且在本地启动时运行良好。因此我不确定哪里出了问题或如何传递此错误。

Startup.cs

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    
    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddDbContext<TestProductContext>(options =>
        {
            options.UseSqlServer(Configuration["ConnectionStrings:Database"]);
        });
        services.AddControllers().AddOData(opt =>
            opt.Filter().Expand().Select().OrderBy().Count().SetMaxTop(100)
                .AddRouteComponents("odata", GetEdmModel()));

        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new OpenApiInfo { Title = "OdataTestProject", Version = "v1" });
            c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
        });

        //// https://docs.microsoft.com/en-us/aspnet/core/mvc/controllers/filters#filter-scopes-and-order-of-execution
        services.AddMvc(opts => { opts.Filters.Add(new AutoLogAttribute()); });
        services.AddApplicationInsightsTelemetry();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseSwagger(c =>
            {
                c.RouteTemplate = "/swagger/{documentName}/swagger.json";
            });
            app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "OdataTestProject v1"));
        }
        app.UseHttpsRedirection();
        app.UseRouting();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }


    private static IEdmModel GetEdmModel()
    {
        var builder = new ODataConventionModelBuilder();
        var entitySet = builder.EntitySet<TestProduct>("TestProducts");
        entitySet.EntityType.HasKey(entity => entity.Id);
        return builder.GetEdmModel();
    }
}

解决此问题的一种方法是删除现有的应用程序，创建新的应用程序并从旧的 project.Check 复制代码，如果您的路径包含任何空格

或

删除 bin 和 obj 文件夹。重新打开项目并让 NuGet 在后台加载（它已删除所有 NuGet 引用）。进行清理和重建
尝试使用最新版本Swashbuckle.AspNetCore.
将 global.json 文件添加到您的 Web API 项目
把这个放进去：

 { 
  "sdk":
   { 
    "version": "3.1.406", 
    "rollForward": "latestPatch" 
   } 
 }

而不是 Swashbuckle.AspNetCore.Swagger nuget 包安装 **Swashbuckle.AspNetCore **.
Swashbuckle.AspNetCore. 包包含以下内置的 nuget 包
