I have an old post about the various options available to you that applies to ASP.NET Core 1.0, but the options available in ASP.NET Core 3.x are much the same: UseUrls() - Set the URLs to use statically in Program.cs. It uses a delegate to configure values for MyOptions: The following code displays the options values: [!code-csharp[~/fundamentals/configuration/options/samples/6.x/OptionsSample/Pages/Test2.cshtml.cs?name=snippet)]. Consider the same appsettings.json file contents from the previous example: The values are accessed using the indexer API where each key is a string, and the value is a string. This method is an extension method for IConfiguration: In the preceding output, Index 3 has value value40, corresponding to "4": "value40", in MyArray.json.

In Solution Explorer, right click the project and select, If a key and value is set in more than one configuration providers, the value from the last provider added is used. In the following code, PositionOptions is added to the service container with Configure and bound to configuration: Using the preceding code, the following code reads the position options: In the preceding code, changes to the JSON configuration file after the app has started are not read. The switch mappings dictionary must not contain duplicate keys. The host is responsible for app startup and lifetime management. {Environment}.json, and user secrets.

To check the current environment while configuring services, use builder.Environment instead of app.Environment. {Environment}.json: Call AddEnvironmentVariables with a string to specify a prefix for environment variables: The prefix is stripped off when the configuration key-value pairs are read. We have a wizard that is executed when the backend indicates it has not been configured (it's only a variable in the appsettings.json). The "commandName" key has the value "Project", therefore, the Kestrel web server is launched. The solution isn't to pass the arguments to CreateDefaultBuilder but instead to allow the ConfigurationBuilder method's AddCommandLine method to process both the arguments and the switch-mapping dictionary.
