Best of DZone: Developing Web Apps and Services With C# and ASP.NET

C# is an interesting language in that it can create both front-end and backend web applications. And, over the past several years, ASP.NET has been at the heart of C#-based development (though ASP.NET Core came onto the scene in August 2017 and has been winning considerable followers). In this post, we take a look at the best tutorials on DZone over the years about C# and ASP.NET development.  Tutorials C# Interfaces, What Are They and Why Use Them?  by Richard McCutchen. Here are the cliff notes: "An interface is a contract between itself and any class that implements it.

Blazor: Modern Web development with .NET and WebAssembly

Blazor is an experimental project to bring .NET to the Web via WebAssembly. In this session you'll see how Blazor enables full stack web apps using C# with no code transpilation or plugins – just open web standards.

ASP.NET Core: Read the GPS Coordinates of a Photo

Image
Bugsnag monitors application stability, so you can make data-driven decisions on whether you should be building new features, or fixing bugs.  Learn more. During one of my ASP.NET Core classes I made a demo about how to read GPS coordinates from photo and display location on a map. I took my favorite photo of a beer kiosk in Krakow and displayed the location of this kiosk on a map. This blog post describes my experiment on getting GPS coordinates from EXIF data in an ASP.NET Core application. Wikipedia defines EXIF  (Exchangeable image file format) as a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners, and other systems handling image and sound files recorded by digital cameras. Most of modern devices used to take photos save meta information in EXIF format to photos. It's great but be aware – not all people may use this information in good purposes. Reading EXIF Data There are some li...

Visual Studio Code Gears Up for Blazor

Image
News Visual Studio Code Gears Up for Blazor By David Ramel 11/30/2018 Microsoft is preparing its open source Visual Studio Code editor to support Blazor, the company's experimental technology for using languages such as C# for Web programming, which is currently dominated by JavaScript. The promise of such a capability is creating a lot of buzz because Web coding using languages other than JavaScript would open up huge opportunities for .NET-centric and other developers. Microsoft's efforts to gear up VS Code for Blazor start with initial support for Razor , its ASP.NET programming syntax for creating dynamic Web pages with C# or VB.NET. That markup syntax for embedding server-based code into Web pages consists of Razor markup, C# and HTML. The company recently announced that Razor support in VS Code was available in preview, baked in to the C# for Visual Studio Code extension available in the Visual Studio Code Marketplace. The initial support introduces f...

At its Microsoft Connect(); 2018 virtual event today, Microsoft announced the initial public preview of Visual Studio 2019 — you can download it now for Windows and Mac . Separately, .NET Core 2.2 has hit general availability, and .NET Core 3.0 Preview 1 is also available today. Microsoft launched Visual Studio 2017 in March 2017 and Visual Studio 2017 for Mac in May 2017 and then released seven subsequent updates to further improve their performance. That was the "most popular Visual Studio release ever," but in June the company announced Visual Studio 2019 for Windows and Mac . As before, Visual Studio 2019 previews will install side by side with Visual Studio 2017, which is great for trying out new functionality without messing with your production workflow. Visual Studio 2019 also won't require a major operating system upgrade, Microsoft promised.
