Different type of json file in asp.net core application

 

ASP.NET Core applications rely on JSON files to manage configuration settings, environment-specific parameters, and other data. These files allow for systematic and flexible configuration management without hard coding variables into the application code.

• appsettings.json
  • the default configuration file where general application settings are stored, such as logging configurations, database connection strings, and API keys. 
  • It is typically located in the root directory of the project. ASP.NET Core automatically loads this file during application startup.
• launchSettings.json
  • Found in the Properties folder.
  • Contains settings related to how the application is launched during development. 
  • It includes profiles for IIS Express and the Kestrel server, specifying URLs, environment variables, and other launch configurations. This file is primarily used in local development scenarios.
  • including:
    • Application URL(s)
    • Environment variables (like ASPNETCORE_ENVIRONMENT)
    • Command-line arguments
    • IIS Express settings (if applicable)
      • 
• appsettings.{Environment}.json
  • These are environment-specific configuration files (e.g., appsettings.Development.json, appsettings.Production.json) that override settings in appsettings.json based on the current environment. 
  • ASP.NET Core determines the environment through the ASPNETCORE_ENVIRONMENT variable, allowing for different configurations in development, staging, and production environments.
• global.json
  • used to define solution-level settings, such as specifying the SDK version and the locations of project directories. It helps maintain consistency across different development environments by ensuring the same SDK version is used.
• project.json (Deprecated)
  • Define project metadata, dependencies (NuGet packages), target frameworks, and build settings.
  • However, this file has been replaced by the MSBuild-based .csproj format in newer versions of .NET Core
• bundleconfig.json
  • used to configure bundling and minification of CSS and JavaScript files. It specifies input files and output locations for bundled resources, optimizing the application's performance by reducing the number of requests and the size of files served to clients. 
• bower.json
  • used when integrating Bower, a front-end package manager, into the project. It lists the client-side libraries and their versions, facilitating the management of front-end dependencies. 
• secrets.json
  • Used during development, this file stores sensitive information like API keys and connection strings. It is part of the ASP.NET Core Secret Manager tool, which helps developers keep sensitive data out of source control. This file is not intended for use in production environments
• Localization Files (.resx or .json):
  • Used for localizing your application's text content for different languages and cultures. While .resx (XML-based) is the traditional .NET format, you can also use JSON files for localization, especially in client-side JavaScript or when you prefer a simpler format.
