PowerShell ISE 啟用 TLS 1.2 (只啟用 .NET 4.X  和 Server, Client)

ASP.NET Core IIS HTTP Error 500.31

IIS 來架設 .NET Core 的站台，需要安裝 .NET Core Hosting Bundle 才能執行

檢查安裝在 IIS 上的 .NET Core Hosting Bundle 版本

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Updates\

Hosting Bundle 各版本下載位置：https://dotnet.microsoft.com/download

安裝後重裝服務

net stop was /y

net start w3svc

在開發時可以看目前用的 core 版本
