我正在调试这个简单的Web应用程序。

namespace HttpCookies
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.Run(async (context) =>
            {
                var cookie = context.Request.Cookies["MyCoolLittleCookie"];

                if (string.IsNullOrWhiteSpace(cookie))
                {
                    DateTime now = DateTime.Now;
                    DateTime expires = now + TimeSpan.FromSeconds(15);
                    context.Response.Cookies.Append
                    (
                        "MyCoolLittleCookie",
                        "Cookie created at: " + now.ToString("h:mm:ss tt"),
                        new CookieOptions
                        {
                            Path = "/",
                            HttpOnly = false,
                            Secure = false,
                            Expires = expires
                        }
                    );
                }

                string response =
                    "<h1>HTTP Cookies</h1>" +
                    $"<p>This is the cookie value received from browser: \"<strong>{cookie}</strong>\".</p>" +
                    "<p>Refresh page to see current cookie value...</p>" +
                    "<p>Cookie expires after 15 seconds.</p>";
                await context.Response.WriteAsync(response);
            });
        }
    }
}

这就是launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            // Use IntelliSense to find out which attributes exist for C# debugging
            // Use hover for the description of the existing attributes

            }
        },

            "type": "coreclr",
            "request": "attach"
        }
    ]
}

当我试着调试这个错误时，
“找不到调试类型'coreclr'的调试适配器描述符（扩展可能无法激活）”
我应该怎么做才能停止这个错误？它工作正常，但突然出现此错误，请帮助
