为什么 Azure 应用服务不使用 launchSettings.json 配置？

Question

I need some help.

I deployed Asp Net Core app on Azure App Service(Windows). It's not use my standart configurations in launchSettings.json

But uses random port per starting. For example :

[INF] Now listening on: "http://127.0.0.1:4340"

[INF] Now listening on: "http://127.0.0.1:8105"

[INF] Now listening on: "http://127.0.0.1:13605"

When I running it in my own computer all routes and ports work correct. Why this situation appear with Azure App Service deploy ?

Answer 1

Because launchSettings.json is exclusively for Visual Studio.

From the documentation :

The environment for local machine development can be set in the Properties\\launchSettings.json file of the project. Environment values set in launchSettings.json override values set in the system environment.

The launchSettings.json file:

• Is only used on the local development machine.
• Is not deployed.
• contains profile settings.

Moreover, even if you switched from Visual Studio to Visual Studio Code, you would have to use the file .vscode/launch.json .
