There's an exception to this rule: if you plan to use the same controller for both views and web APIs, derive it from Controller. The following request body is an example of the serialized type: See How to log automatic 400 responses on model validation errors (dotnet/AspNetCore.Docs#12157). {Environment}.json, and user secrets. The web API project template provides a starter controller: C# [ApiController] [Route (" [controller]")] public class WeatherForecastController : ControllerBase Web API For all other library guidance, see Open-source library guidance. The provider has the following characteristics: Define an EFConfigurationValue entity for storing configuration values in the database. The ApplicationPartManager tracks the application parts and feature providers available. If the Support pages and views checkbox is selected to support pages and views when generating the RCL from the template: Add an _Imports.razor file to root of the generated RCL project with the following contents to enable Razor component authoring: Add the following SupportedPlatform item to the project file (.csproj): For more information on the SupportedPlatform item, see the Browser compatibility analyzer for Blazor WebAssembly section. So, here are the steps to make this work. The key is the file name. Create a ClassLibray (.net core) named "MySharedApp", and add the following package via NuGet. A platform compatibility analyzer warns the developer when the app uses APIs that aren't supported by the app's target platforms.

The [ApiController] attribute can be applied to a controller class to enable the following opinionated, API-specific behaviors: The [ApiController] attribute can be applied to specific controllers, as in the following example from the project template: One approach to using the attribute on more than one controller is to create a custom base controller class annotated with the [ApiController] attribute. The [Consumes] attribute allows an action to limit the supported request content types. Making statements based on opinion; back them up with references or personal experience.

The CreateDefaultBuilder method's AddCommandLine call doesn't include mapped switches, and there's no way to pass the switch-mapping dictionary to CreateDefaultBuilder. To switch to the latest, use the ASP.NET Core version selector at the top of the table of contents. Therefore, key values read from the environment override values read from appsettings.json, appsettings.
