Why will you want to impersonate a user? Isn’t it a bad thing to do? when should it be used? Let’s say you have a user of your system, this user faces an issue or a bug he/she desperately tries to explain but you just can’t understand what he is explaining. Wouldn’t it be good […]
Validation is an important part of APIs. When using a clean architecture, or another modern application design pattern, most often we leverage CQRS’ commands for actions like POST, PUT, etc. These commands have side effects. While those without side effects like GET requests are implemented in queries. Commands most often need some sort of asynchronous […]
Have you ever worked on migrating from a legacy system to a newer one? That’s what I’m doing, and I learn a lot from this every day. Today we’ll learn how to translate tokens with identity server. Specifically, we will use tokens issued with Forms authentication ticket to make authenticated API calls on APIs protected […]
Messaging services like WhatsApp keep bragging about end-to-end encryption (E2EE) telling us how it keeps our data safe even if messages we send are intercepted by a third party. Have you ever wondered how this works? how come they are able to secure our messages over the internet ? Well, I’ve asked myself those questions […]
Hello Friends, while building your mobile app, I’m sure you’ve already come across a situation where you need your app to do some time-consuming work in the background, without interfering with the user’s experience. Such tasks might include synchronizing data, sorting data, unzipping large files, etc. Though C# gives us a way to run asynchronous […]
Hi friends. Nearly every application nowadays talks to APIs or processes data from an internal database. These tasks are time consuming and most of the time are done in the foreground. Since they are done in the foreground, we have to inform the user that some important work is going on. The most basic way […]
Hello friends, today we will solve a little problem which a few people might encounter while building APIs in ASP.net core. This will be a very short post, since we will go straight to the point with the solution. We will see how to in ASP.net core upload files and json data for each file […]
While building Xamarin Forms applications there are several things that you find yourself repeating again and again. These might include creating value converters, markup extensions e.t.c. These repetitions could be made a lot easier using Xamarin Forms Snippets. And that is what we are covering today. This article is part of my contribution to Xamarin […]
Hi friends, here we are again, my first blog post in 2020. Today we will talk about how to navigate to a page and wait results. This can be really useful by making our code easier to read, as compared to using Xamarin Forms’ Messaging Center each time a page needs to send back results […]
Hi friends. Nowadays, mobile applications are rarely standalone. They most often require a back-end with which they communicate. This back-end provides a means of storing, retrieving and processing data from any device which the app runs on. Taking this into consideration, it is obvious you will want to secure this data. This can be done […]
