Question

我刚刚创建了一个新的asp net core 2.0应用程序，并添加了nuget的招摇。

当我尝试运行应用程序时，我在启用stdout日志后出现以下错误：

Application startup exception: System.MissingMethodException: Method not found: 'Void Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenOptions.IncludeXmlComments(System.String)'.

Application started. Press Ctrl+C to shut down.

这是我的Startup.cs

public class Startup
    {
        private StartupExtensions StartupExtensions { get; set; }
        private IConfigurationRoot Configuration { get; set; }
        public Startup(IHostingEnvironment env)
        {
            StartupExtensions = new StartupExtensions($"{env.EnvironmentName}");
            Configuration = StartupExtensions.Init();
        }



        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            StartupExtensions.ConfigureServicesExtensions(services, Configuration, new SwaggerConfiguration
            {
                Title = "EmergencyEvent Api",
                Version = "v1",
                Description = "API de integração HDI"
            }, false);

            // Dependency Injection

            services.AddScoped<IAuthenticationProvider, IturanAuthenticationProvider>();
            services.AddScoped<IIturanAuthenticationService, IturanAuthenticationService>();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            StartupExtensions.ConfigureExtensions(loggerFactory, app, Configuration, new SwaggerConfigurationUrl
            {
                ApiDevelopmentName = "api.emergencyevent",
                ApiStagingName = "api.emergencyevent",
                ApiProductionName = "api.emergencyevent"
            });
        }
    }

我已尝试从startup.cs中删除swagger配置，但应用程序仍未运行。

对我来说，解决方案（或解决方法）是将Swashbuckle从2.5降级到2.4（以前运行良好）。

未找到Swagger方法IncludeXmlComments（System.String）
