Configuring Different Environments

[ardalis]

ASPNET > Getting Started

Describe environment variable support in ASP.NET. Focus mainly on the Environment environment variable, which is exposed via IsDevelopment in Startup's methods.

• Show how to use the environment to request a different configuration settings file (e.g. settings.development.json).
• Show how to only show developer error page if IsDevelopment
• Show how to use launchSettings to set the environment (in Visual Studio, anyway)
• Show how to manually set environment variables in Windows and Mac
• Show how to use environment-specific methods in Startup (e.g. ConfigureDevelopment)
