Token based authentication and Identity framework in ASP.NET Core - Part 2
.NET229 titlesSetting 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.

Remote PowerShell Core session to a Linux host from Windows machine
PowerShell24 titlesRemote sessions using OpenSSH from Windows to Linux host
0
Starting from January 2018, Microsft has made PowerShell Core 6, a cross-platform tool available not only to Windows users which was the case so far with previous versions, but to Linux and Mac users as well.
Since it was tool for Windows only, it had it's own ways for remoting using WinRM unlike Linux operating systems which primarily rely on SSH. Windows is great for editing and development, I find it really comfortable to work on with so many tools and platform available...read more

Sending email in ASP.NET Core using SmtpClient and dependency injection
.NET229 titlesUsing 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.

Advanced versioning in ASP.NET Core Web API
.NET229 titlesDifferent 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
