With this server, the ASP.NET Core app and IIS run in the same process. Model property names are generally an implementation detail, which can make them difficult to handle from single-page apps. The gRPC HTTP API project started out as an experimental project in the AspLabs repo, but we are planning to turn it into a supported feature for .NET 7. Weve learned about the importance of error and exception handling standardization in our web APIs. We saw how to enable the CORS in ASP.NET Core API applications, will see more about ASP.NET Core in my future articles. The ASP.NET Core Web Host is available only for backwards compatibility. After choosing the Blazor WebAssembly App template in the Create a new ASP.NET Core Web Application dialog, {NAME} is the app's client name in the OAuth 2.0 Client IDs app list of the Google APIs console. Youre correct that we still rely on .NET IL interpretation in some cases when using ahead-of-time (AOT) compilation for WebAssembly. Lets create an ASP.NET Core web application. This is a poor solution as it can hide compilation errors, which then become apparent once you push to a build server and the directive becomes true/false. Authentication support for standalone apps is offered using OpenID Connect (OIDC). Do you really want to assume and rely on it that this is already set in every environment you use? How to read JSON file into string specifying values and using System.Text.Json?
