.NET Core

In this post, we'll look at some pitfalls and ideas EF Core users like yourself may want to consider when developing an application. Entity Framework Core (EF Core) is a ground-up rewrite of Microsoft's object-database mapping framework. Getting started with EF Core is relatively straightforward, but mastering it can take an entire career. As a long-time user of earlier Entity Framework versions,

In 2019, we held our first JetBrains .NET Day Online. After a succesful repeat in 2020, we want to again host sessions by community speakers at the JetBrains .NET Day Online 2021 on May 12, 2021. JetBrains .NET Day Online is a free virtual event where community speakers cover topics they are passionate about, ranging from deep technical .NET content and speakers' experiences with specific tools an

Ah, December. A great month! It provides us with some downtime, there are a number of holidays, and it's the month where I turn 37. December also brings a chance to look back at the past year, and that's exactly what we wanted to do in this blog post: look back at our 2020 webinars, and look forward to 2021. 🤔 JetBrains Webinars? Each month, we try to bring you at least one session where c

During the last several days, I've been experimenting with an Apple M1 device from the perspective of a .NET Developer using a typical developer toolkit: .NET SDKs, Node, JetBrains Rider, other editors, and mobile emulators. For .NET developers considering using an Apple M1 for their daily development machine, we'll see what it is currently like to work on these devices. The goal is not to get eve

As developers, we love tools. But often, too much tooling gets in the way when trying to develop applications quickly. Have you ever been ripping through code when you want to refactor or do a common task, but just can’t find the command for it because there are too many distractions? It’s very frustrating! Let’s take a look at how ReSharper brings back simplicity when using an IDE, with its famou

With the .NET 5 release comes the newest Entity Framework Core version, unsurprisingly called Entity Framework Core 5 (EF Core 5). The .NET community got its first glimpse of Entity Framework (EF) on August 11th, 2008, with the release of .NET Framework 3.5 Service Pack 1. Let's say a few things have changed since the initial release. For those unfamiliar with the technology, Entity Framework is a

Hi-diddly-ho Blazorinos! A long-lived mantra of the .NET community has concentrated on transferable knowledge of C# into different paradigms, including desktop, mobile, web, and embedded systems. Blazor continues that trend of using what we know to build new and exciting solutions. Blazor has recently garnered a lot of buzz in our industry, focusing on bringing C# programming to frontend HTML expe

In the latest Rider 2020.3 Early Access Preview (EAP) builds, we're bringing in Project Dependency Diagrams from ReSharper! With project dependency diagrams you can visualize project dependencies in your solution, and explore its architecture. In this post, we'll have a look at what project dependency diagrams look like, what information they show, and how we can use them to analyze project coupli

How often do you reach for a profiler? Only when things go wrong, right? All too often, we use profilers only as a last resort, even though dotTrace and dotMemory are both pleasant to work with. What if we told you that Dynamic Program Analysis (DPA) in ReSharper automatically analyzes the memory usage of your applications and helps catch difficult-to-diagnose memory allocation issues before we de

The recording of our webinar, Service Creation via .NET Core Templates, with Olga Nelioubov, is now available. Subscribe to our community newsletter to receive notifications about future webinars. Custom .NET templates are a fantastic way to bootstrap your .NET services, however they're not only limited to the .NET world – their usefulness could extend to templating out pipelines, applications in

Get out your dirndl and lederhosen - it's that time of year again! We're excited to be sponsoring Hacktoberfest 2020. Hacktoberfest is an opportunity for contributors worldwide to give back to their favorite projects in the form of pull-requests. In this blog post, you will find out what Hacktoberfest is, as well as a nice surprise by JetBrains. But there's more! We'll share types of activities yo

One of the wonderful things about .NET is the vast array of platforms .NET developers can target. My personal experience has been developing ASP.NET applications and HTTP APIs, but recently I've been dabbling with mobile applications built using Rider and Xamarin.Forms. For those curious, or maybe even a little scared, about working with Xamarin.Forms, well, don't be. I've found the Xamarin.Forms

Hello folks! With the Rider 2020.2 release out of the door, we're looking toward the future. After sharing our ReSharper 2020.3 plans earlier this week, we'll now look at our plans for Rider 2020.3. Your feedback is welcome and encouraged. The following is a set of highlighted features our team is currently working on. Let's get started. .NET 5 – Our plan is to put significant time and effort to

If you are already using nullable reference types, you might have noticed that they can help make your code safer. But not automagically... This feature relies heavily on everything called by your code being annotated. Unannotated APIs are a big problem for nullable reference types, as they never produce warnings. Values from such calls show extremely optimistic non-null hints, even though there a

With each passing day, the .NET ecosystem introduces new target environments. In addition to Windows environments, we can now deploy to Linux, macOS, and all popular mobile operating systems. Having these options is excellent, as it allows us to reach a broader audience, but each new environment comes with its own set of challenges. .NET Framework has solved the multiple-environments issue by crea

Where and when does a value in our program change? And what's the state of values in each iteration, when debugging recursive functions? Two good questions that Rider 2020.2 EAP helps answer, with Data Breakpoints and Pin-to-Frame! (more…)

Folks who use your software want to-the-second updates. Especially in a business setting, where people need to get things done, and get them done at "the speed of business". Company dashboards showing sales and their projections often need information to be available in real-time to really get that competitive advantage. Even users of personal apps such as social networking want to see replies and
