Asp .net core 1.1 web app发布到天蓝色找不到资源

Question

我刚刚尝试将我的 asp .net 核心 Web 应用程序发布到 Azure，但无法正常工作。当我点击浏览时，我会收到此消息

Picture when I try to browse to my published website

我试图在日志中查看以找出问题所在并找到此消息

<Error>
  <Code>ResourceNotFound</Code>
    <Message>
        The specified resource does not exist. RequestId:64038d84-0001-0068-1019-55d321000000 Time:2016-12-13T08:19:53.3494003Z
    </Message>
</Error>

我认为它可能是在我尝试查找连接字符串的项目的“startup.cs”中。

项目的 Github 链接：https://github.com/AlexJCarstensen/ITTWEB-ASPNetCore

我尝试获取连接字符串链接：

services.AddDbContext<EmbeddedStockContext>(options =>
   options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));      

我已在 App Settings 和 Connection strings 中将此设置添加到该应用的 Application settings 中，但仍然找不到它。

所以问题是如何在其 应用程序设置 中从 Azure 获取连接字符串？

信息：我在 linux 上开发，所以无法访问 Visual Studio。

希望你能帮忙

在跟进 Dmitry 评论后，我发现了详细错误消息所在的日志。

错误信息是这样的：

显然 Azure 不支持 UserSecrets 的功能。 如果您想了解有关 UserSecrets 的更多信息。 微软在这里有一些信息：

https://docs.microsoft.com/en-gb/aspnet/core/security/app-secrets#security-app-secrets

在我们的项目中，我们使用它在 windows 和 linux 机器上进行开发，以将不同的连接字符串保存在 userSecret 中。这不适用于 Azure。

希望这对其他人有所帮助。
