Differences in Time Zone Formats in .NET Core on Windows and Linux host
.NET200 titlesOvercoming TimeZoneInfo load problem on different operating systems in .NET Core
0
Recently I was working on converting DateTime value to a different time zone because the servers are running in a different time zone than the database where data is stored. Storing DateTime values in UTC time zone is the best practice, so simple DateTime.ToUniversalTime method call solves the problem.
But what in case you need to save in the specific timezone and your different server where you application is running on...read more

Sending email in ASP.NET Core using SmtpClient and dependency injection
.NET200 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
.NET200 titlesDifferent 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

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?
