    Introducing Windows Presentation Foundation (WPF) Animations wpf-animations.png

    When it comes to web pages, HTML is the tool to present the elements and CSS to provide the styling. Sure, there are exceptions and embellishments but, in short, that is how it boils down. If you want to implement some sort of animation or have something move, and it’s more complex than the simple animations supported by CSS, you generally have to fall back on JavaScript. In contrast, these aspects of presentation, styling, and animation are all an integral part of the Windows Presentation Foundation XAML.

    XAML stands for Extensible Application Markup Language, and it is a declarative language that describes WPF’s elements, relationships, and behaviors. XAML elements map directly to Common Language Runtime (CLR) object instances and XAML attributes correspond to the properties and events of CLR objects.

    In this tutorial, you will explore the various ways to animate visual elements in …

    Monitoring Web Server Performance with Windows Presentation Foundation and ScottPlot wpf-scottplot (1).png

    Windows Presentation Foundation (WPF) framework provides a rich graphical user interface for desktop applications. Charts are a familiar component in many applications, providing users with a visual way to consume data, observe trends and patterns, and provide a more attractive and engaging application.

    Many libraries provide various charting capabilities. In selecting a library to use, you should consider many factors. Foremost is compliance and compatibility with the framework used to implement the project.

    If you’re building a new .NET project these days, it’s likely you’ll be using .NET Core, so the charting library you select has to be compatible. Since .NET Core is relatively new, compared to the .NET Framework, there are fewer libraries available. 

    Some charting packages are big, feature-rich, time-consuming to learn to use, and expensive. In many large applications, these tools provide continuity between components while also providing a high degree of styling, which is very desirable. …

    Understanding Windows Presentation Foundation (WPF) Data Binding with the DataContext Class In .NET Core wpf-datacontext.png

    The Windows Presentation Foundation (WPF) framework allows you to develop desktop applications with amazing graphic capabilities, but it does not stop there. An application needs to display data of some sort and connecting UIElements to underlying data structures needs to be flexible. That is where DataContext comes into play.

    DataContext works hand-in-hand with data binding to provide hierarchical data presentation. It is what connects the front end to the code-behind and enables changes made to data in the user interface to update the data source, and conversely, while maintaining the order of your data structure. You’ll see  examples of this in the case study project for this post.

    This tutorial will guide you through building a WPF application where you can explore DataContext at work. You will create a data dashboard that visualizes data from different simulated sources.

    Prerequisites

    You’ll need the following tools and resources to build and run …

    Understanding Windows Presentation Foundation Routed Events In .NET Core wpf-routed-events.png

    Windows Presentation Foundation (WPF) is a very powerful framework for building desktop applications. Unlike Windows Forms, WPF provides the capabilities of nested UIElements, animation, layered presentation, and more. The focus of this tutorial is to demonstrate the aspects of Routed Events.

    Routed Events are a construct specific to WPF that supports event routing. It allows for the processing of events in a very flexible fashion to meet a particular capability.

    User interface elements (UIElements) have the ability to nest elements. A panel can contain a button which can contain a panel. Within that panel could be an image and some text. The user then clicks the mouse button. What element is expected to handle the event? Is it the text or the image? It could even be the panel that holds them or the button itself.

    A common practice is to add a mouse click handler for a …

    Getting Started with Windows Presentation Foundation (WPF) in .NET Core getting-started-wpf.png

    Windows Presentation Foundation (WPF) is a user interface framework for building desktop applications. Implementing Extensible Application Markup Language (XAML) to define and script views, it has become the standard for Windows application user interfaces. Introduced in 2006, Microsoft has reenergized its commitment to WPF with its inclusion into .NET Core.

    The tutorial in this post will guide you through creating a project that will mimic many of the basic functions of a word processor. You will be surprised at how easy it is to implement many features with standard tool elements. You will be introduced to some of the many constructs of WPF and create a foundation for experimenting further.

    Prerequisites

    You’ll need the following tools and resources to build and run this project:

    Windows 10 – It puts the Windows in Windows Presentation Foundation.

    .NET Core SDK 3.1 – The SDK includes the APIs, runtime, and CLI.

    Visual Studio …

    Getting Started with gRPC in .NET Core getting-started-with-grpc (1).png

    As a developer in the 21st century, you are often faced with addressing communications between various modules of your project. Internal, or “intra-process” communications, are often handled with loosely coupled messages, but forging beyond the process boundary can often be challenging. Adding to this requirements for scalability, testing, and security can often leave you scratching your head in search of a better way.

    Over the years Microsoft has often revealed various technologies to handle this niche. Remote Procedure Calls (RPC), DCOM, Named Pipes, and Windows Communication Foundation (WCF) are examples of technologies that have fit the bill in the past. A new technology is now making the scene, this time with the assistance of Google.

    For over 10 years now, Google has implemented an infrastructure to interface the vast number of microservices it oversees. In 2015, they set out to create the next version of this technology and shared what …
