Here is how iFour’s .NET experts tried these .NET 10 latest features in their real projects and hear what they have to say about their experience in using them. 1. Blazor improvements in ASP.NET Core 10 Security and authentication are critical factors that could make or break your project. With .NET CORE new release, Blazor has got faster with better security metrics. Blazor script now served as a static web asset with compression & fingerprinting. QuickGrid gets RowClass for conditional row styling. Navigation improvements: NavigateTo no longer scrolls to top on same-page navigation. Read More: ASP.NET SignalR for real time applications Krunal Patel, Project Manager at iFour Technolab USA, says - KR Krunal Patel "The new Blazor updates can be useful for any industry application, let's say a hospital management app. The faster loading would be a big win because doctors don't like waiting! Also, the static asset handling makes deployments smoother. QuickGrid's RowClass can save you a lot of CSS headaches when you are to highlight critical patient rows." 2. Security and Authentication One of the biggest highlights is passkey support (WebAuthn + FIDO2). This means you can now log in without passwords - using biometrics or security keys instead. It’s more secure and phishing-resistant. Mayur Mehta, Sr. .NET developer at iFour shares his experience on ASP.NET Core 10 authentication metrics. He says - MM Mayur Mehta "We built passkey authentication in our client's healthcare portal, and honestly, it made life so much easier. Patients do not have to remember passwords anymore, so logins were very smooth. And the best part is the reduced number of support tickets for forgotten passwords. That's a big relief for both users and the support team." Blazor also comes with updated templates that support Microsoft Entra ID, OpenID Connect (OIDC), and Windows Authentication right out of the box. 3. Components and UI Improvements in .NET 10 QuickGrid RowClass- Add conditional styling easily. HideColumnOptionsAsync- Control column options programmatically. Better navigation- Updating query strings won't scroll the page to the top. NavLink updates- Active links stay highlighted regardless of query parameters. Simplify identity governance and access control with Microsoft Entra ID Streamline Access Monika Mistry, Sr. .NET Developer at iFour shares: MM Monika Mistry “QuickGrid saved us hours while building admin dashboards. Instead of writing custom logic for conditional styling, the RowClass parameter did the job seamlessly.” 4. Performance and Asset Management Blazor now optimizes asset loading with client-side fingerprinting and preloading static assets. This means faster first loads and smoother updates. Dhruv Jain, .NET Core Developer at iFour: DJ Dhruv Jain “We tested this on a Blazor WebAssembly app for one of our fintech clients, and honestly, the difference we noticed was huge. Preloading those static assets reduced the first load time by almost 25%. That means users do not have to stare at a blank screen for long. It just felt way quicker and smoother. This is an important aspect for any industrial app. And for a finance app where speed matters, this has been a big win.”   Learn more about ASP.NET Core 10 performance updates here. 5. .NET MAUI Blazor Hybrid Blazor Hybrid lets you build apps that work on desktop and web using the same code. So if you want a desktop feel but still need web access, this is perfect. Rahul Shiyani, .NET developer, Legal Project, iFour explains: RS Rahul Shiyani "For a legal case management tool, we went hybrid with Blazor. It was cool because lawyers wanted a desktop feel but also needed web access. The improved integration made it super easy to share components between both." Read More: What is Blazor web assembly? 6. SignalR improvements in ASP.NET Core 10 ASP.NET Core 10, which is part of .NET 10, has made SignalR a lot better. Now it’s way easier to build real-time stuff like live chats, dashboards, and apps where people can work together at the same time. Krunal Patel, Project Manager, Fintech Project, shares his take: KP Krunal Patel “So, we recently built a real-time stock dashboard for a fintech client, and honestly, performance using SignalR was noticeable. It was amazing, price updates were instant, even when thousands of users were online at the same time. No lag, no delays, no complaints. It just worked, and that's exactly what you want in a trading app.” 7. State Management and Persistence Now, .NET experts can use the [PersistentState] attribute to easily keep component state, even during network interruptions or tab freezes. No more writing boilerplate code for session handling! Jinal Gandhi, .NET Expert, iFour puts it about her experience JG Jinal Gandhi “We had issues with user sessions dropping during poor internet connectivity. The new circuit state persistence in Blazor 10 fixed this problem, making the app more reliable for field users.” 8. JavaScript Interop Improvements in .NET Core 10 Another best feature you would observe in ASP.NET Core 10 is how easily you can work with JavaScript right from .NET. You can create JS objects, call their constructors, even handle async methods; all without leaving your .NET code. And yeah, you can manipulate properties too. It just makes mixing .NET and JavaScript so much smoother. Build custom workflows and apps with expert Microsoft 365 Development Start Building Smarter 9. Minimal APIs Improvements in .NET 10 Minimal APIs in .NET 10 now come with first-class validation support. Add AddValidation() and the framework takes care of validating request models using DataAnnotations or custom rules. Minimal APIs are also great for microservices or quick endpoints. This latest version provides more lightweight capabilities than the earlier versions. Jinal Mehta, .NET Team Lead, says: JM Jinal Mehta “We used Minimal API validation in an internal HR app. It eliminated manual checks, reduced bugs, and gave us consistent error messages via ProblemDetails.” Sarbeshwar Partihary, .NET Developer, Healthcare Project: SP Sarbeshwar Partihary "So, at iFour, we recently worked on an appointment booking service, and we decided to try out Minimal APIs. Honestly, it was so easy and lightweight, really quick to set up, and perfect for microservices. No heavy boilerplate, just building straightforward features. It saved us time and kept everything clean and simple." Read More: ASP.NET Core improvements in .NET 5 10. Server-Sent Events (SSE) "ASP.NET Core 10 now supports SSE, or Server-Sent Events, and that’s a critical aspect for real-time updates. It’s perfect for things like dashboards, live notifications, or streaming data. The best part is, it’s way simpler than setting up WebSockets, so you get real-time without the extra complexity” Neha Sakaria, Project Manager at iFour emphasizes: NK Neha Sakaria “We were building a logistics tracking app, and we needed live vehicle updates. Normally, you’d think WebSockets, right? But that can get messy. So, we used SSE (Server-Sent Events), which was so simple, just triggers updates straight to the browser. No heavy setup, no headaches. And it worked very smoothly even with hundreds of users online.” Scale your tech team with top-tier talent Hire .NET developers today Hire Now 11. Smarter Form Handling Using .NET 10 Another best update to talk about is Form validation enhancements in .NET 10. Now you can manage forms smartly just by registering AddValidation() and using [ValidatableType] and get it running. Empty strings in form posts now get treated as null for nullable types. This small tweak reduces a lot of unnecessary parsing errors. Devangini Dubey, Sr. .NET Developer, iFour remarks: DD Devangini Dubey "We upgraded to ASP.NET Core 10 to work on a Legal e filing portal. Technically, it allowed us to map the empty strings to null on the portal’s form. This eventually eliminated the need for validation on optional fields like ‘MiddleName’ and ‘AptNo’. Users could leave stuff blank without breaking anything, and our logs got way cleaner. We even discarded a bunch of custom checks - less code, fewer tickets." Read More: ASP.NET CORE API with Entity Framework 12. OpenAPI 3.1 and Documentation ASP.NET Core 10 brings full OpenAPI 3.1 support, including: JSON Schema draft 2020-12 compliance Support for YAML docs Automatic XML documentation from your code comments Dhruv Kalaria, API Specialist, iFour Technolab states his opinion on this DK Dhruv Kalaria "We had to integrate multiple APIs in our legal’s client’s project, and OpenAPI 3.1 support has made our job a lot easier. YAML format made documentation very clean, that even a non-tech person can understand easily. In addition, compliance with JSON Schema 2020-12 kept everything standard."
