C# - 发布配置文件中的自定义环境变量

Question

We are using .Net Core 3.1 and we have multiple publish profiles. In each there is

<EnvironmentName>Development</EnvironmentName>

or Production etc. I would like to add another variable which is named by me.

Answer 1

Unfortunately you can not register any other environment variables when you publish, only the EnvironmentName.

The same thing can be achieved like

dotnet publish -c Debug -r win-x64 /p:EnvironmentName=Development

if you want to clear out your csproj file.

Coming back to environment variables, I can see two solutions:

1. Move to a docker solution and pass the environment variables into your container. That is pretty easy and straight forward. Link to docker documentation
2. Add a powershell script that will set the variables in the server.

Answer 2

You can only set the environment variable in your publish profile. You can name it anything you want. To set other variables you would have to use web.config transformations .
