JetBrains Rider - configure appsettings overrides

Question

I am trying JetBrains Rider for my existing .NET Core project. In the project I have several appsettings.json overrides:

• appsettings.Development.json - for development
• appsettings.Test.json - for testing
• appsettings.Staging.json - for staging environment
• etc.

In Visual Studio, the overrides work perfectly and I always get my Development override, when running the app in debug mode. However, in Rider I am getting the default appsettings.json values, which are not suitable for debugging and development. How do I change the settings to get the values from the correct override?

Answer 1

You'll need to set the ASPNETCORE_ENVIRONMENT environment variable.

To do this, create separate configurations for each environment:

Then click Edit Configurations

I create one for each env - and specify the Environment variable as appropriate:

Note that this setting in the configuration overrides the actual environment variable; I had exported it in my ~/.bash_profile but it was always reverting to Production. – Porte

No matter what Environment Variables I set in the Run Config, it always selects appsettings.json – Venettavenezia

@Venettavenezia -- did you ever get this working? Does not work for me, I always get the main appsettings.json copied to output. – Whale

@Whale Yes, see my answer below: https://mcmap.net/q/490252/-jetbrains-rider-configure-appsettings-overrides. If you're working on a shared project, it may cause colleagues issues if you check in the setting, though. – Venettavenezia

Answer 2

For the Mac interface:

1. Choose the config you wish the to change the environment

2. Select Environment variables

3. Choose 'Development' or 'Production'

Answer 3

The accepted answer didn't work for me. I had to enter the environment variable ASPNETCORE_ENVIRONMENT=Development in to the "Runtime arguments" field:
