WebAssembly

With the start of a new year, it’s common to reflect on what happened over the past year and plan for the upcoming year. In this article, I’m going to look at the state of WebAssembly in 2020 and where I see things going this year. Before we jump in, for those of you who may be unaware of what WebAssembly is, I’ll give you a quick primer. What is WebAssembly? WebAssembly, which you might also see abbreviated as Wasm, is a low-level assembly-like language that is designed to be safe, fast, compact, portable, and a compilation target. That’s a bit of a mouthful but, basically, it’s not designed to be written by hand. You use a higher-level language and compile to it. The files are designed to be as small as possible so that they can be transferred and downloaded quickly. They’re also structured in such a way as to optimize validation and parsing so that the module can start up as quickly as possible. From the beginning, the desire was to be able to use WebAssembly modules outside the browser as well but the initial work was in the browser. Regardless of where they’re used, you need to

A few weeks back Syncfusion announced their UWP Charts now support Uno Platform and run on WebAssembly. We’ve worked together with Syncfusion team to make this a reality. As this happened just during the UnoConf timeframe, these important news might have gotten lost in the buzz of announcements we made – support for Linux, experimenting with Tizen, Material and Fluent out of box support etc etc. So with this blog we simply want to surface out these beautiful line-of-business charts you can use in WebAssembly today. After all, what is a great looking LOB application without some pretty and interactive charts – right? Syncfusion has released thirteen charts compatible with WebAssembly – see them in action below. We’d also love to hear from you about which should be the next control we work on together with Syncfusion – drop by Uno Platform channel at UWP Discord community to let us know. Currently thirteen charts are supported: Column chart Bar chart Line chart Spline chart Area chart SplineArea chart Scatter chart Bubble chart Pie chart Doughnut chart Semi pie chart Semi doughnut chart Stacked doughnut chart For detailed steps on how to embed these charts in your solution please see Syncfusion

This article covers Implementing custom module validation in an ASP.NET Core MVC web application Using Emscripten to create a WebAssembly module that can be used outside the browser Using WebAssembly modules in your C# code Imagine you’re working for a company who’s about to build a web application for expense reimbursements. Before they do, they task you with building a prototype to evaluate several things including if WebAssembly can be leveraged both on the client in JavaScript and on the server in C#. For the prototype, you’ll create an ASP.NET Core MVC web application. The MVC application has good built-in validation but the final product will need some additional custom validation. For the prototype you’ll keep the validation simple because you just want to know if it’s possible to use WebAssembly in both the browser and in the C# code. The following image shows the two web pages that you need to build for this prototype: For this prototype, you’re going to implement WebAssembly validation in the JavaScript for the Amount field and in C# for the Description field. Validation is performed in the browser primarily so that a web application is more responsive to the user’s actions. For example,
