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 an object-relational mapper (ORM), helping developers overcome the impedance mismatches between C# and a database instance's schema. Entity Framework has come a long way since its original inception.

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 experiences. In this post, we'll go one step further and see how we can embed Blazor into an Electron app to ship Blazor on the desktop. We'll also look at how we can debug our Electron application using

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 coupling in a solution. Hello, project dependency diagrams! You can open the project dependency diagram from the context menu in solution explorer, or by using the Tools | Architecture | Show Project Diagra

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 deploy them to production. Because we all know an unhappy user is an unhappier developer, let's see how DPA can keep us happy! What is DPA? A simple description would be "it's a kind of memory prof

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 other languages, configuration files, or anything else that can be opened with a text editor. Furthermore, they are extremely simple to set up and can be easily packaged and distributed to others for

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 you can contribute, and a list of .NET projects that need your help. Let's start at the beginning... 📯 Hacktoberfest For those unfamiliar with Hacktoberfest, here are the basic rules of particip

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 community to be welcoming and very helpful to a mobile newbie like me. I've also found the platform itself to be straightforward to get started and iterate on as I've learned new approaches to solving

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 support the upcoming release of .NET 5. While development is possible in Rider today with .NET 5, it is incomplete. .NET 5 is the future of .NET, and we want to help developers get there. More Perform

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 are no guarantees that these hints are correct. Here's a compiler issue for this problem. For example, if you are using LINQ's FirstOrDefault() method from .NET Core 3.1, the compiler not only allows y

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 creating the .NET Standard. The .NET Standard exposes a common API we can compile against with the understanding that our target environments have a context-specific implementation. In this post, we'll se

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…)
