Back when we were getting ready to ship .NET Core 2.0, I wrote a blog post exploring some of the many performance improvements that had gone into it. I enjoyed putting it together so much and received such a positive response to the post that I did it again for .NET Core 2.1, a version for which performance was also a significant focus. With //build last week and .NET Core 3.0‘s release now on the horizon, I’m thrilled to have an opportunity to do it again. .NET Core 3.0 has a ton to offer, from Windows Forms and WPF, to single-file executables, to async enumerables, to platform intrinsics, to HTTP/2, to fast JSON reading and writing, to assembly unloadability, to enhanced cryptography, and on and on and on… there is a wealth of new functionality to get excited about. For me, however, performance is the primary feature that makes me excited to go to work in the morning, and there’s a staggering amount of performance goodness in .NET Core 3.0. In this post, we’ll take a tour through some of the many improvements, big and small, that have gone into the .NET Core runtime and core libraries in order to make your apps and services leaner and faster. Setup Benchmark.NET has become the preeminent tool for doing benchmarking of .NET libraries, and so as I did in my 2.1 post, I’ll use Benchmark.NET to demonstrate the improvements. Throughout the post, I’ll include the individual snippets of benchmarks that highlight the particular improvement being discussed. To be able to execute those benchmarks, you can use the following setup: Create a directory named BlogPostBenchmarks. In that...
Now that you are aware of the phases of an app development project and the cost associated with them, we can move on to the tips to manage and reduce the cost of your app development project. Note down the essential features It is a good idea to think about the functionality of your app before you start working on it. Understand the problems that you want to solve and list down the features that you want to include in the app. While some of the features and functionalities are easy to implement, others will require considerable effort and money to implement. Since the cost of features varies with projects, it is difficult to put a price tag on them. To build your app without exhausting your entire budget, only include the features that are critical to the functionality of the application. Once you have a Minimum Viable Product (MVP), which contains only the essential elements, you can test it and later add more features as an update. You can also cut the development costs by using pre-built features. For instance, instead of spending your time and money on developing your own push notification functionality, you can simply choose a third-party plugin. Numerous service providers offer these pre-built solutions at a nominal price. Consider the location of the app developer Although, every company and developer charges differently, their cost massively depends on their location. For instance, app developers from North America and Australia charge as much as $150/hour on average. In contrast, developers in Eastern Europe and the Indian subcontinent may cost as low as $30 per hour on...
Azure Active Directory’s gateway service is a reverse proxy that fronts hundreds of services that make up Azure Active Directory (Azure AD). If you’ve used services such as office.com, outlook.com, or xbox.live.com, then you’ve used Azure AD’s gateway. The gateway provides features such as TLS termination, automatic failovers/retries, geo-proximity routing, throttling, and tarpitting to services in Azure AD. The gateway is present in more than 53 Azure datacenters worldwide and serves ~115 Billion requests each day. Up until recently, Azure AD’s gateway was running on .NET Framework 4.6.2. As of September 2020, it’s running on .NET Core 3.1. Motivation for porting to .NET Core The gateway’s scale of execution results in significant consumption of compute resources, which in turn costs money. Finding ways to reduce the cost of executing the service has been a key goal for the team behind it. The buzz around .NET Core’s focus on performance caught our attention, especially since TechEmpower listed ASP.NET Core as one of the fastest web frameworks on the planet. We ran our own benchmarks on gateway prototypes on .NET Core and the results made the decision very easy: we must port our service to .NET Core. Does .NET Core performance translate to real-life cost savings? It absolutely does. In Azure AD gateway’s case, we were able to cut our CPU costs by 50%. The gateway used to run on IIS with .NET Framework 4.6.2. Today, it runs on IIS with .NET Core 3.1. The image below shows that our CPU usage was reduced by half on .NET Core 3.1 compared to .NET Framework 4.6.2 (effectively doubling our throughput). As a...
.NET Core 3.0 Preview 3 was released last month, and it includes a bunch of new updates to ASP.NET Core. There are a couple of updates related to Angular . In this new update, the default Angular template is updated to Angular 7 and the option to add authentication while creating an Angular or React application. In this post, we’ll see how to create an Angular 7 app with Visual Studio 2019 and add authentication to Angular 7 App using ASP.NET Core 3. Add Authentication to Angular 7 App using ASP.NET Core 3 Before we create the application, first we need to install Visual Studio 2019 and .NET Core 3.0. Install .NET Core 3.0 To download .NET Core 3.0 preview 3, visit this link. Based on your platform, download the appropriate installer. This will not impact your existing .NET Core version installation. Install Visual Studio 2019 Preview To install Visual Studio 2019 preview, download the installer from this location. Don’t worry . Visual Studio and Visual Studio “Preview” can be installed side-by-side on the same device. It will have no impact on your current stable VS installation. At the time of writing this post, you can’t set the Authentication while creating the angular based SPA application with Visual Studio 2019. The option to change the authentication is disabled. However, using the .NET CLI you can create the project via the following command. dotnet new angular –auth Individual This command creates a new ASP.NET Core application with a hosted client Angular application. The application uses an Identity Server instance already configured so that your Angular application can authenticate users and...

2021 is a great time to learn Laravel and improve your knowledge if you’ve been using it. To start the year off we’ve made a list of 21 tutorials on everything from getting started to going deeper with the framework. Getting Started with Laravel Tutorials In this tutorial, you’ll go through building a simple link directory app. It covers everything from planning, setting up your database, Blade views, and more. Join our weekly Laravel newsletter and get this as a free PDF. Laravel Eloquent Laravel Eloquent is an object-relational mapper (ORM) that makes it easy to interact with your database. When using Eloquent, each database table has a corresponding “Model” that is used to interact with that table. In addition to retrieving records from the database table, Eloquent models allow you to insert, update, and delete records from the table as well. At its core Eager Loading, is telling Eloquent that you want to grab a model with specific relationships that way the framework produces a more performant query to grab all the data you will need. By eager loading, you can take many queries down to just one or two. In this tutorial, you’ll set up some example relationships and then walk through how queries change with and without eager loading. If you’ve been working with Laravel for any time, you probably know the standard methods for creating Eloquent Models like make(), create(), update, and save(). Laravel includes some other methods are that also really useful for creating and updating Models that I feel don’t get enough attention. In this tutorial, you’ll learn about some of these additional...
