Question

所以我目前正在基于Linux的配置中在Azure App Services上运行Blazor .NET Core服务器端应用程序，以下是我的环境

System info
System up time: 5.05:06:19.3920000
OS version: Unix 4.15.0.112
64 bit system: True
64 bit process: True
Processor count: 1
Short instance id: bdcba9
CLR version: 4.0.30319.42000
System directory:
Current working directory: /opt/Kudu
IIS command line: /opt/Kudu/Kudu.Services.Web.dll

昨天一切运行良好，但是到今天为止，我对某些文本进行了细微更改并重新发布。突然间，我现在在kudu日志流中收到HTTP 500错误。当尝试获取我认为是不正确的参数的cultureinfo时，您可能会看到它崩溃（也许是GetMethodFromHandle），即使将其设置为可以击中所有/所有异常类型，它在本地也可以正常运行，没有问题，也没有任何异常。我的应用程序中也没有地方设置CultureInfo或使用Locale。

我不太确定是什么原因造成的，并想知道其他人是否有类似的东西或可能会有所启发。我了解它从操作系统中汲取了文化，但我的端部没有任何变化，并且以前可以正常工作。我不确定在本地可以尝试什么，我有点倾向于Azure App / Linux配置中的问题，但是.. hmph

我不一定会称其为解决方案，但我基本上注意到，在部署时，并没有像推送文件那样重新启动Web服务器。我删除了该应用程序并将其重新添加到部署列表中，以使其开始再次执行此操作，瞧。现在，它在部署后会重新启动，并且似乎可以再次工作。
