Web application development has evolved with the rise of new technologies and frameworks. Two of the most popular technologies for building interactive web applications are Blazor and React. In this article, we will compare Blazor and React and highlight their differences with examples.
.NET Conf: Focus on Blazor is a free, one-day livestream event that features speakers from the community and .NET product teams that are working on building web apps with C# and Blazor. You don't need to use JavaScript anymore with Blazor technology! Blazor lets you build interactive web UIs using C# instead of JavaScript.
Razor Pages is a new feature of ASP.NET Core MVC that makes coding page-focused scenarios easier and more productive.
Razor Pages requires ASP.NET Core 2.0.0 or later. Tooling support for Razor Pages ships in Visual Studio 2017 Update 3 or later.

OVERVIEW
Razor components are specific building blocks within the Blazor framework. They can perform many roles: representing a specific piece of the user interface, a view component, or a tag helper; or representing a layout or an entire page. In Razor Components Succinctly, you will explore how to create and work with both simple and advanced Razor components. Longtime Succinctly author Ed Freitas will show you how to write a basic component using one-way data binding and events, and then two-way data binding, event callbacks, life cycle methods, and component references. Finally, you'll see how to enable component reuse by creating a component template.

can’t be the only person who hates waiting for the code to compile and run… Especially when I want to test only a small part of it! That’s a total waste of time! But good news everyone, I found a way to run a part of my C# code without building the whole project!
In Chrome 80 and later, cookies will default to SameSite=Lax. This means that cookies will automatically be sent only in a first party context unless they opt-out by explicitly setting a directive of None.
But if you’re a web developer, you should start testing your sites and services now to help ensure a smooth transition.
