If the user-requested routedata is found, the requested page (or root page) is displayed. If the user-requested routedata is invalid (not found), it displays a “sorry” message to the end user. Today, it’s common to have an application that runs across devices, a backend on the web server, and an admin front-end on Windows desktop, web, and mobile apps for consumers. The main objective of .NET Core is to make .NET Framework open-source, cross-platform compatible, that can be used in a wide variety of verticals, from the data center to touched-based devices. It includes the core features that are required to run a basic .NET Core app.

• These are the service classes in the shared library that are also used by the MVC and Razor Pages web apps in NetLearner.
• In this course you will first learn about the history and basics of ASP.NET Core.
• Also, you need to use different .NET APIs for different Windows devices such as Windows Desktop, Windows Store, Windows Phone, and Web Applications.
• I am not able to make a call to GetEmployees() function in EmployeeDapperService.cs class.
• Here, the value for SearchString is used by the OnGetAsync() method in the Index.cshtml.cs class for ResourceLists.

You can even use your Razor knowledge to work on Blazor fullstack web development. This “app” (formerly defined in a static “index.html” in pre-release versions) is now defined in the aforementioned “_Host.cshtml” page. Note that the Configure() method takes in an app object of type IApplicationBuilder, similar to the IApplicationBuilder we see in regular ASP .NET Core web apps.

In addition to server-side Blazor (released in late 2019 with .NET Core 3.1), you can also host Blazor apps on the client-side from within an ASP .NET Core web app. asp net razor tutorial Client-side Blazor is currently in preview and is expected in a May 2020 release. Note that the Startup class doesn’t have to be called Startup, but you do have to tell your application what it’s called. Instead, you just need a call to AddServerSideBlazor() in ConfigureServices() and a call to MapBlazorHub() in Configure() while setting up endpoints with UseEndPoints().
