+
+Command line configuration provider implementation for [Microsoft.Extensions.Configuration](https://www.nuget.org/packages/Microsoft.Extensions.Configuration/). This package enables you to read configuration parameters from the command line arguments of your application. You can use [CommandLineConfigurationExtensions.AddCommandLine](https://learn.microsoft.com/dotnet/api/microsoft.extensions.configuration.commandlineconfigurationextensions.addcommandline) extension method on `IConfigurationBuilder` to add the command line configuration provider to the configuration builder.
