项目场景：
部署基于abp的后端于iis报500.30 In-Process Startup Failure
问题描述：
以下截取自微软官方文档：
500.30 In-Process Startup Failure
The worker process fails. The app doesn’t start.
The ASP.NET Core Module attempts to start the .NET Core CLR in-process, but it fails to start. The cause of a process startup failure can usually be determined from entries in the Application Event Log and the ASP.NET Core Module stdout log.
Common failure conditions:
•The app is misconfigured due to targeting a version of the ASP.NET Core shared framework that isn’t present. Check which versions of the ASP.NET Core shared framework are installed on the target machine.
•Using Azure Key Vault, lack of permissions to the Key Vault. Check the access policies in the targeted Key Vault to ensure that the correct permissions are granted.
