As ASP.NET was evolving, there were different ways accessing client IP address from the request. The way to do it WebForms and MVC Web application is simply accessing request of the current HTTP context ...read more

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

.NET Core comes with a great feature for loading different config file based on the environment. Environment is picked up from the host environment variables whether that is Windows on Linux based OS...read more

Recently I wrote and article about using asymmetric keys for token based authentication in ASP.NET Core. As I was setting up the RSA keys to test the demo appliation I kept running to some challanges that did not make thigs going so smooth Challenge number 1 - OpenSSL ...read more

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

Some time ago I wrote about setting up .NET Core service/daemon on Linux. Back than I was using .NET Core 2.0 SDK on both development Windows machine and Linux host machine...read more

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

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

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

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

Recently I wrote and article about setting up and using Google reCAPTCHA v2, better known as "I'm not a robot" validation. If you were setting up reCAPTCHA v2, you probably noticed that there is an option for "Invisible reCAPTCHA" option. This type of validation, instead of asking user to interact with the UI in order to be identified as a human, does not require any direct interaction which can help building better user experience for your visitors...read more
