Setting up token based authentication in ASP.NET Core application on top of Identity Framework
0
In article Token based authentication and Identity framework in ASP.NET Core - Part 1 I described how to setup identity library for storing user accounts. Now we are going to setup ASP.NET Core Web API project to issue the token for authenticated users so they can access protected resources. Identity Web API instance will be separated from from the resource Web API, so we'll have eventually two and possibly in future more resource services which will all use single identity server fr authentication and issuing access tokens. ...read more

Sending email in ASP.NET Core using SmtpClient and dependency injection
Using dependency injection to send email in ASP.NET Core
0
Starting with .NET Core 2.0, Microsoft introduced SmtpClient, identical implementation as in .NET 4. This made sending emails from the application a lot easier as there is functionality out of the box and you do not have to rely on the 3rd party nuget packages. If you inspect this class, you will see that the only interface it inherits is IDisposable, so it does not give you many options for injection unless you wrap it with your own implementation and interface, but since we are not going to go that deep into the dependency injection, we'll just focus on creating a client instance using .NET Core dependency injection framework. ...read more
Advanced versioning in ASP.NET Core Web API
Different approaches in ASP.NET Core Web API versioning
0
Some time ago I wrote an article about ASP.NET Core Web API versioning which describes route based Web API endpoint versioning. I love route versioning and to me it is the best way of versioning because it is pretty straight, but there are situations where this kind of versioning is not suitable. On nuget.org you can find Microsoft.AspNetCore.Mvc.Versioning package which gives you more options on how you can version your Web API endpoints...read more

Many of you who had chance to work docker and .NET Cote on Linux will agree that easiest way of running .NET Core on Linux is to pull microsoft/aspnetcore:2.0 image from docker repository and just setup your app with .Dockerfile. You will be saved of the hassle of setting up the environment and .NET Core on on the Linux machine. But what if that is not an option? What if you really need for some reason to run your application on the specific host and not in the container? ...read more

Redis health check in ASP.NET Core WebApi
Checking availability of distributed Redis cache instances in ASP.NET Core WebApi
0
Even before popularity of micro service approach, for even monolithic applications you needed to have health-checks (Google Compute Engine) or health-probes (Microsoft Azure) for load balancing. Basically in load balancing scenario, these endpoints are used to tell load balancer whether instance can handle requests or not. Since handling of requests may consider several components, these endpoints either return 200 OK HTTP response or any other response like 500 Internal Server Error with optional payload message describing the issue and each component status. ...read more
