C# (pronounced see sharp, like the musical note ) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, declarative, imperative, functional, generic, object-oriented, and component-oriented programming disciplines. It was introduced in 2000 by Microsoft as part of its .NET initiative, and later approved as an international standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018).
In order to retrieve an embedded resource in .NET Core, we first need to understand how the resource name is composed. It’s got 3 elements, all joined by dots (.): Let’s take a concrete example. We have a project (assembly) with a root namespace MyApp.Core. Inside our project we’ve got a folder + subfolder like…
There are two key differences compared to ASP.NET: To get started, add an appsettings.json file in your shared project. Make sure you set it’s Build Action to Embeded Resource. Add some keys + value in the file that we can use for testing. For example: Next, we need to get hold of the resource stream….
When dealing with mobile clients, it’s not always easy to get them on the same network as your development machine and even when you do, localhost will have a different meaning so you need to use IPs and change bindings and disable SSL or trust self-signed certificates, in short it’s a pain. Say hello to…
Ever wished you’d declare something which gets disposed automatically when it’s enclosing scope finishes executing without adding yet another set of curly braces and indentation to your code? You are not alone. Say hello to C# 8 using declarations 🥰. With using var you can now do: instead of: No more unecesary curly brackets, no…
The operator enables you to assign the right-hand operand value to the left-hand operand only if the left-hand operand value evaluates to null. Let’s take a very basic example: In the example above we declare a nullable int variable i and then make two null-coalescing assignments on it. During the first assignment i will evaluate…
I’ve started playing with animations in Xamarin Forms only recently and created a cool background animation for one of my apps (Charades for Dota 2) which I thought I would share. So without any extra introduction, this is the final result: The GIF is a bit jittery but that’s just because by PC can’t handle…
This is a question that came after during discussion with a colleague over some company worth over 20 trillion dollars – and we just couldn’t imagine how that much money would look like in cash. Just to get an idea of it, we calculated how many hundred dollar bills it would take to circle the…
To add speech recognition to our app we will be using the newly released version of the Windows Phone toolkit (release June 2013) – which adds a nice new control called SpeechTextBox (that does exactly what you think). You can get the latest build using NuGet or you can download the source from CodePlex. Once you’ve…
I’ve covered in a previous post how to create wide tiles for your Windows Phone 7 application. Now it’s time to bring them to life. The easiest way to do so is by using a ScheduledTaskAgent. To create one go ahead and add a new project to your solution and from the project templates list…
I’ve recently come across an article in the Nokia Developer Wiki about creating live tiles (including wide tile) for both Windows Phone 7 and Windows Phone 8 by writing a single piece of code that works in both versions of the OS. To do this you will need to use the MangoPollo library which you…
Below you have an extension method that can help you convert any hex color code to a Color object. The method above can only convert 8 characters ARGB color codes.In order to convert simple RGB codes too we will check for the length of the string (9 = ARGB and 7 = RGB) and in…
Code snippets are a great way of improving your productivity because they allow you to define pieces of code which you can later on insert into your projects by using a short alias. Although they’ve been in Visual Studio for quite some time not many people know what they are, what exactly they do and…
