Token based authentication and Identity framework in ASP.NET Core - Part 3

Setting up asymmetric key token based authentication in ASP.NET Core application on top of Identity Framework
Recently I wrote about setting up .NET Core Identity Framework and Token based authentication in ASP.NET Core using symmetric key signing. The downside of this approach is that both identity and resource server share the same key for signing and validating the token...read more

Token based authentication and Identity framework in ASP.NET Core - Part 2

Setting up token based authentication in ASP.NET Core application on top of Identity Framework
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
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
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

Use different configuration based on environment value in ASP.NET Core

Different configuration per environment in ASP.NET Core
In .NET framework, having separate configuration is possible by having different web.config or app.config file transformations since in .NET framework configuration is stored in XML format. You can check more on this in article Separate configuration files per build config in Visual Studio IDE...read more

How to setup ASP.NET Core run on Debian Linux with Nginx

Hosting and running ASP.NET Core project on linux
In two previous articles (How to setup .NET Core 2 on Debian or Ubuntu Linux distro the easy way & Setting up .NET Core service/daemon on Debian Linux OS) I explained how to setup and run .NET Core based applications and how to run them as a Linux daemon. In this article we are going to take it one step further...read more

Setting up .NET Core service/daemon on Debian Linux OS

How to run .NET Core application as daemon on Linux
I found a lot of articles out here on this subject, but non of them actually made the daemon work from the first time. There was always some catch I had to chase and found in some other article posted online. In this article I will try to cover as much as possible how to setup .NET Core daemon working on a clean Debian 9 Linux machine...read more
