Simple script for building and publishing .NET Core application to Docker
Build and publish .NET Core application to Docker container or Kubernetes

Recently I wanted to try to spin up a simple .NET Core application on my local cluster which I built in my previous article Manual setup of Kubernetes cluster on a Virtual Machine with kubeadm. The problem I had is that I needed to test applications in this cluster and deploy them as service in order to monitor potential issues behavior. As deployment of Kubernetes service needs an image to pull from, I decided to use dockerhub to push my test images, but they first needed to be created. ... read more
Creating Windows service and Linux daemon with the same code base in .NET
Cross-platform service with C# and .NET Framework
0
Few months back I wrote an article on how to create Linux daemon in .NET Core using generic host class introduced in 2.1 version of .NET Core. This code works just great on Linux OS when configured as a daemon in systemd and provides more less same concept you would have with Windows Service written in .NET Framework 4.x. The code works just fine on both Windows and Linux hosts, but because it is compiled as a Console Application, you do not really get to run it on your Windows machine as a Service... read more
Minify ASP.NET MVC Core response using custom middleware and pipeline
Html response content minification on the fly in ASP.NET Core

For my website, since it runs on Umbraco 6 and it is basically ASP.NET MVC application. To reduce load time and increase website performances I decided to alternate the response of the application and minify it using simple regular expression. Initially I was trying to do this with YUI Compressor library which has .NET port as NuGet YUICompressor.NET which works fine in most of the cases, but in my case does not skip PRE tags which I use for code snippets on the website... read more

Caching common data like lookups for example in memory of your app can increase significantly your MVC web application performances and response time. Of course this data has to be periodically refreshed. You can use various approaches to refresh data including expiry, but this can create potential bottle necks in your application since once data expires, you will use request thread to pull the data, cache and serve the request response back... read more

Differences in Time Zone Formats in .NET Core on Windows and Linux host
Overcoming 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
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

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
