配置Swagger

Question

我在Net Core 3.1中有一个Web API，我正在尝试配置Swagger，但我会遇到此错误：

我当前有启动。CS配置如下：

public void ConfigureServices(IServiceCollection services)
        {
            ...
            AddSwagger(services);

        }

private void AddSwagger(IServiceCollection services)
        {
            services.AddSwaggerGen(options =>
            {
                var groupName = "v1";

                options.SwaggerDoc(groupName, new OpenApiInfo
                { Title = "Core Library", Version = "v1", });
            });
        }

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            ...

            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "Core Library");
                c.RoutePrefix = String.Empty;
                c.DocumentTitle = "";
            });

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

我还缺少什么？你能帮助我吗？

谢谢你！！
