将 chrome 更新到版本 88.0.4324.104 后，控制台窗口出现以下错误

Error with Permissions-Policy header: Parse of permission policy failed because of errors reported by strctured header parser.

该应用程序使用 Aurelia SPA 从 ASP.NET Core 3.1 开发。尝试将以下中间件添加到后端

app.Use(async (context, next) =>
           
{      
         context.Response.Headers.Add("Permission-Policy", "geolocation 'none';midi 'none';notifications 'none';push 'none';sync-xhr 'none';microphone 'none';camera 'none';magnetometer 'none';gyroscope 'none';speaker 'self';vibrate 'none';fullscreen 'self';payment 'none';");
         await next(); 
});

但仍然收到控制台错误。

我使用asp.net mvc脚手架创建了一个Web表单表单,如果没有回发,它不能进行客户端验证.[Required()]是postbacking,[EmailAddress]验证器正在客户端验证.我使用visual studio 2013和asp.net mvc 5和ef6.这个id我的模型类:

更新到版本 16.10.0 后，无法从 Visual Studio 2019 调试 azure 函数。得到以下错误。

我有一个包含以下数据模式的数组

"coordinates" : [

          482035.86720000021,

使用Newtonsoft Json将此json字符串反序列化为对象的正确映射类结构是什么
