Build Blazor Apps Faster With C# Components

Blazor is developed by Microsoft and represents free, open-source web framework that enables developers to create feature-rich web apps using C#, HTML code and Razor syntax instead of JavaScript. Building server-side apps happens with Blazor Server, while Blazor WebAssembly executes client-side apps directly in the browser. Infragistics is an active contributor and supporter of Blazor.

Blazor is a framework for building modern web applications that run in the browser that are built with .NET. Blazor let you build web apps with two different rendering models – a server-side (Blazor Server) or a client-side (Blazor WebAssembly) model.

• Blazor Server applications are ASP.NET Core hosted apps on the server running ASP.NET Core Razor pages. Processing is done on the server, with client HTML page updates done via a SignalR connection from the server end point.
• Blazor WebAssembly is a single-page application (SPA) framework that runs .NET assemblies written in C# directly in the browser. WebAssembly, an open standard for running binary code in web pages. In this mode, your code is executing against a .NET runtime that is downloaded with your application.
No matter which of the two approaches you use for your web application, both let you build you web apps using C# for both client and server code instead of JavaScript, while still allowing you to use any JavaScript library with Blazor’s JavaScript interop bridge.

The unique value of Blazor is that you create apps with C# instead of JavaScript, giving .NET developers an excellent choice for building new, interactive experiences on the web, including a great path for moving from desktop apps to web apps. While JavaScript frameworks come and go, ASP.NET from Microsoft is still going strong after 20 years. While there have been different flavors and iterations of ASP.NET, a common, consistent theme in every version of ASP.NET is the C# programming language and the .NET Framework. Used by millions of developers for 2 decades, the power and flexibility of the .NET Framework runs the largest (and smallest) companies in the world today. With Blazor, there is a path forward for building web apps with a modern framework. In terms of the what the future holds, Microsoft has a strong roadmap for Blazor, both Blazor Server and Blazor WebAssembly. Platform features, performance enhancements and long-term support with .NET 5 and moving to .NET 6 have also been announced by Microsoft. At Infragistics, we believe Blazor has a strong future, and we are investing in UI controls and components so you can build the best possible apps with Blazor.

A Blazor App is an interactive, modern web application built using ASP.NET, C# and the .NET Framework that can run any type of line-of-business application, productivity application or SaaS application on the web. ASP.NET Blazor is a Blazor is a framework for building interactive client-side web UI with .NET. Blazor apps are different than Angular or React apps in these ways:

• Developers use C# instead of JavaScript, but they are not excluded from using JavaScript.
• Developers can take full advantage of the .NET Framework which has decades of security and reliability built in.
• Application logic can be shared across the client and server using ASP.NET Core.
• Developers have a choice if a server-based model using ASP.NET Core, or a pure client-side model using WebAssembly.
• Blazor WebAssemby processing is entirely done in the browser on the client, using a .NET runtime. A Blazor app is built using C# classes, C# libraries or JavaScript libraries, and Razor pages. Razor pages are represented as .razr files, and let developers combine HTML markup with C# code in a single page.

A Blazor component is reusable .NET C# class built into .NET assemblies that are used for client-side UI logic and composition. A Blazor component represents an element of the UI (C# code, HTML markup, other components) of a Blazor web application like a page, form, data grid, data chart or any aspect of a page that gets rendered as HTML. A component handles interactions, events, and rendering logic. Components can be nested and reused in a web app or in different web apps as Razor class libraries or NuGet packages. The benefit of the Razor page for Blazor components is that a developer can include HTML markup, JavaScript and C# in a single file, using the power of Visual Studio intellisense and debugging to accelerate component and page development. Infragistics ships over 30 Blazor components, and we are investing in Blazor components heavily in 2021 to further bring you what you need to build your apps of the future.

Performance is critical to the success of any application framework. If operations are slow, pages render slow, interactions are slow, there will be no adoption of a framework. Microsoft knows this better than anyone. With Blazor, like any new technology, there are always issues that come up with a version 1, some of them related to performance. The biggest pushback with Blazor is around the size of the package that includes the .NET Framework and the WebAssembly of the actual application being run. Since WebAssembly is more than a simple HTML page, it includes DLL’s and binaries that are sent from the server to the client, there is a risk of a larger initial payload, which could affect your app if it is a SaaS app on the web. For internal line-of-business apps, payload size is usually not relevant. Microsoft is committed to addressing performance issues in Blazor, from the initial payload size to the overall performance of runtime execution on the client. At Infragistics, we expect these issues to be addressed between now and when .NET 6 is released in the fall of 2021.

Blazor is production ready, in fact, many small business and enterprise companies are using Blazor today. Blazor was first released by Microsoft in 2018, but the excitement for Blazor hit a high around the official release of Blazor WebAssembly on May 19th, 2020. Blazor WebAssembly closely matches the SPA (Single Page Application) pattern for writing applications that Angular and React follow. This means an application is not dependent on a web server to perform business logic, it can run in the browser and the web server is only necessary to serve static content to the client. Even better, a .NET developer, who knows C#, can build modern, interactive web applications using Blazor without having to know JavaScript. At Infragistics, we see huge interest in Blazor, we believe Blazor is production ready especially for internal line-of-business applications that you might consider migrating from Windows Forms or WPF to the Web. We see growth picking up in 2021 and customers starting in earnest in 2021 building Blazor applications.

Creating a Blazor app is simple.

Prerequisites for a Blazor App

1. Install Visual Studio 2019 version 16.6 for Windows or version 8.6 for Mac with ASP.NET and Web Development installed.
2. Install .NET 5 SDK if you are using Visual Studio Code

Creating a Blazor App with Visual Studio

1. Open Visual Studio.
2. Click Create a New Project.
3. Select Blazor App then click Next.
4. Change the Project name, Location and Solution name, or leave the defaults, then click Next.
5. Choose Blazor Server App if you want to create a server-side web app using ASP.NET Core or choose Blazor WebAssembly App if you want to create a WebAssembly that will run on the client.
6. If you chose Blazor WebAssembly App, check the ASP.NET Core hosted checkbox, as you app's assets are deployed as static files to an ASP.NET Core server to serve the static content to the clients.
7. Click the Create button.

Creating a Blazor App with Visual Studio Code with Command Line

1. In Visual Studio Code, open a new Terminal.
2. At the Terminal prompt, type one of the following, based on the type of Blazor app you’d like to create, Blazor WebAssembly or Blazor Server:

dotnet new blazorwasm

dotnet new blazorserver

To learn all the options for creating Blazor apps at the command line, use the -h to get the Help options

dotnet new blazorwasm -h

dotnet new blazorserver -h
