IIS 发布后解除锁定
1、CMD管理员下运行命令
C:\windows\system32\inetsrv\appcmd unlock config -section:system.webServer/handlers
C:\windows\system32\inetsrv\appcmd unlock config -section:system.webServer/modules
2、由于先装.net 4.0以上版本，后装.net 4.0，需要重新注册.net 4.0
C:\>cd windows\microsoft.net\framework64\v4.0.30319
aspnet_regiis.exe -i
3、Windows Server 2019 安装.Net Framework 4.5
cmd.exe下逐条运行
dism /online /enable-feature /featurename:IIS-ISAPIFilter
dism /online /enable-feature /featurename:IIS-ISAPIExtensions
dism /online /enable-feature /featurename:IIS-NetFxExtensibility45
dism /online /enable-feature /featurename:IIS-ASPNET45
4、应用程序集启用32位
