Generates POCO classes based on appsettings.json files (.NET Core)

Source Generator for generating POCO classes based on your appsettings.json files

This Source Generator generates POCO's based on your appsettings.json files. It also supports multiple settings files: appsettings.json + appsettings.Development.json + appsettings.Production.json, etc.

1. Add the appsettings.json files to your .csproj like this:

  <ItemGroup>
    <AdditionalFiles Include="appsettings.json" />
    <AdditionalFiles Include="appsettings.Development.json" />
  </ItemGroup>

You can add as many appsettings files as you want :)

2. The config classes are generated in the namespace ApplicationConfig (This will be configurable in the next release).
3. Register your config in the DI container: builder.Services.Configure<ApplicationConfig.MyAppConfig>(builder.Configuration);
4. Inject the config in your constructor: IOptions<ApplicationConfig.MyAppConfig> options

⚠️ You may have to restart Visual Studio after installing this NuGet package!
