You already know how role-based authorization works in ASP.NET Core.

[Authorize(Roles = "Administrator")]
public class AdministrationController : Controller
{
}

But what if you don't want hardcode roles on the Authorize attribute or create roles later and specify in which controller and action it has access without touching source code?

DynamicAuthorization helps you authorize users without hardcoding role(s) on the Authorize attribute with minimum effort. DynamicAuthorization is built at the top of ASP.NET Core Identity and use identity mechanism for managing roles and authorizing users. 

By default RavenDB allow anonymous access only for read requests (HTTP GET), 
and since we creating data, we need to specify a username and password. 
You can control this by changing the AnonymousAccess setting in the server configuration file.
Enter your username and password of your Windows account and a sample data will be generated for you. 

Last year, Mike Rousos posted a great post about token authentication on the .NET blog and demonstrated how you could leverage ASP.NET Core Identity and OpenIddict to create your own tokens in a completely standard way.  

Blazor Hybrid for Beginners
Join James Montemagno as he takes you on a journey of building your first Hybrid applications across iOS, Android, Mac, Windows, and Web with ASP.NET Core, Blazor, Blazor Hybrid, and .NET MAUI!  You will learn how to use Blazor Hybrid to blend desktop and mobile native client frameworks with .NET and Blazor.
In a Blazor Hybrid app, Razor components run natively on the device. Components render to an embedded Web View control through a local interop channel. Components don't run in the browser, and WebAssembly isn't involved. Razor components load and execute code quickly, and components have full access to the native capabilities of the device through the .NET platform. Component styles rendered in a Web View are platform dependent and may require you to account for rendering differences across platforms using custom stylesheets.
Blazor Hybrid support is built into the .NET Multi-platform App UI (.NET MAUI) framework. .NET MAUI includes the BlazorWebView control that permits rendering Razor components into an embedded Web View. By using .NET MAUI and Blazor together, you can reuse one set of web UI components across mobile, desktop, and web.
 

With the release of Free Style 1.0, I figure it's about time to write about Free Style - how it works, why you'd want to use it and little introduction to CSS-in-JS. This has been a long time coming, with my first commit to Free Style over a year ago, and the first commit to Free Style in its current form 10 months ago. This is not a blog post designed to sway decisions - as always, you should use your own fair judgement. 

Fast timer plugin for countdown and count forward Demo

With this plugin you can easily put a timer on your site, it works both ways. You can use two version, one version is the version for modern browsers with the standards of the ES2017 and the version for old browsers with ES2015 standards. Using the config you can change the tags as letters and numbers, you can also change the text output next to the numbers.

Build Real App in Angular 10 and ASP.Net Web API

These are 2 of the hottest frameworks right now for the ‘back-end’ (Microsoft’s ASP.NET Core) and the ‘front-end’ (Google’s Angular) and are well worth spending the time to learn.
This course starts from scratch, you neither need to know Angular 1 nor Angular 2
We will start from nothing and incrementally build this property dealing application front-end using Angular 10.
And then we will connect our front-end with the Web-API until we have a fully functional Web Application that we will publish to Firebase and then on IIS.

Problem / solution format brings an easier understanding on how to build things, giving an immediate feedback. Starting from this idea, the blog post will present step by step how to build

a web application to store your ideas in an easy way, adding text notes, either from desktop or mobile, with few characteristics: run fast, save on the fly whatever you write, and be reasonably reliable and secure.

This blog post will implement just the backend, WebApi and the database access, in the most simple way. Next blog post will cover the front end, using Angular. Then, there will be an additional article on how to increase the performance and the security.
