In today's rapidly evolving development landscape, the need for creating high-performance, responsive business applications is more crucial than ever. Blazor, a cutting-edge web framework from Microsoft, empowers developers to build sophisticated business applications with a unique blend of .NET and web technologies.

By using Blazor's server-side capabilities, developers can create modern Single Page Applications (SPAs) while minimizing the need for JavaScript. This approach not only speeds up the development process but also enhances the debugging experience and leverages existing .NET skills and libraries.

Expert Blazor programmer Michael Washington will help developers get a handle on this tech in his upcoming session at the big Visual Studio Live! developer conference coming to Microsoft headquarters in August. In a session titled, "Creating Business Applications Using Blazor," he will guide attendees through the core concepts of Blazor, such as binding, routing, and JavaScript interoperability.

With a hands-on demonstration, attendees will see how to create a complete business application that integrates data, implements Google and Microsoft authentication, and incorporates a custom chatbot. Whether you're a newcomer to Blazor or looking to deepen your expertise, this session promises invaluable insights into building secure, high-performance business applications using Blazor's powerful ecosystem.

Ahead of the session, we had the opportunity to sit down with Michael to discuss what attendees can expect and the latest trends in Blazor development. Here's what he had to share.

VisualStudioMagazine: What inspired you to present a session on this topic?
Washington: Blazor is constantly evolving, and there's always something new and exciting to discuss. It's the technology I use daily, both professionally and in my personal open-source projects.

How does Blazor's component-based architecture enhance the development of business applications?
Blazor has a vast ecosystem of components, covering everything from data grids to themes and even full application frameworks like CMS solutions.

This enables companies and developers to achieve a significant return on investment when using Blazor for their business applications.

Can you provide examples of how Blazor facilitates seamless integration with existing .NET libraries in business applications?
Blazor is built on .NET, so anything designed for .NET works seamlessly with it. For example, I have several projects integrating Azure OpenAI and Azure Authentication. Additionally, many of Microsoft's sample applications, which were previously built with MVC, are now written in Blazor.

What are the key performance optimization techniques recommended when developing business applications with Blazor?
I have developed over 100 applications with Blazor, and 99% of them use Blazor Server. That's my first recommendation. The only times I've used Blazor WebAssembly are when the application needs to function without internet connectivity.

How does Blazor's support for WebAssembly impact the scalability and responsiveness of business applications?
I built an application called aistorybuilders.com that allows users to create AI-generated stories. This free application serves thousands of users worldwide, and using WebAssembly enables me to distribute and maintain it at no cost. However, for typical business applications, I only use WebAssembly when users may not have consistent internet access but still need to use the application.

What best practices should be followed to ensure secure authentication and authorization in Blazor business applications?
For all new applications, I use Microsoft Entra and Azure B2C because multi-factor authentication, threat analysis, and security protections are essential for business applications.

What resources can attendees use to learn more about this topic and prepare for your session?
My website, blazorhelpwebsite.com, is where I blog about Blazor topics, provide examples, and share in-depth insights.

Note: Those wishing to attend the session can save money by registering early, according to the event's pricing page. "Save $400 when you register by the June 6 deadline," said the organizer of the event, which is presented by the parent company of Visual Studio Magazine.
