.net core framweork for building application in 2027 (MAUI , MVC , Balzor)

Hello @john john Pter , and thank you for your questions. 

For your first concern about the difference between Blazor and .NET MAUI, Blazor is for building web interfaces using C#, HTML, and CSS. .NET MAUI generally uses C# and XAML to build applications for mobile and desktop platforms. 

The differences are fairly easy to grasp in practice but can seem vague when described only in words. I would therefore strongly suggest creating a basic application with each, or even starting with a MAUI Blazor Hybrid application. 

As for whether these tools can support the type of application you currently build with MVC, MAUI Blazor Hybrid allows Blazor components to run inside a MAUI application. Since Blazor supports the kinds of interfaces used in typical web applications, none of the asset-management features you listed raises an obvious concern. Administration pages, asset management, relationships, dashboards, and external integrations can all be implemented through this approach unless you have more specific requirements behind them. 

MVC views and Blazor components broadly serve the same role in the web interface, so you would normally choose one rather than build the same interface with both. If reusing interface components between the web and mobile applications is important, Blazor together with MAUI Blazor Hybrid would be the more suitable direction. 

Your concern about its lower adoption is understandable. MAUI Blazor Hybrid is a more specialized choice, but for a .NET developer who wants to reuse Blazor components across web and mobile applications, that specialization is also its main advantage. You can remain within the .NET ecosystem and use Blazor for both the web interface and much of the interface hosted by the mobile application. Some platform-specific work may still be required, but this can avoid maintaining two entirely unrelated interface technologies. 

If you found my response helpful or informative, I would greatly appreciate it if you could follow this guide for your confirmation. Thank you. 

To get the maximum code sharing between a mobile app and a web site you need to architect a n-tier solution. You want the mobile app and the website to only be UI, and both make calls to a common webapi business logic website. You can use the webapi template for this server.

You will need a common security system for both. Oauth is probably the best choice and you can use the Microsoft identity platform:

For the web ui you have three choices. Use MVC, razor pages or Blazor. As it’s a UI only site I’d pick razor pages over MVC. While Blazor uses razor syntax, it uses razor components which are not compatible with Razor Pages or razor views. Picking Blazor would allow sharing the UI code between the website and the mobile app if Blazor Hybrid is picked.

You should review the Blazor architecture before picking. For a Blazor website, it is either a server app that uses WebSockets to connect to the client browser. There is a dedicated connection, memory and threads for each connected user, so server scaling can be an issue. Blazor server also requires a reliable network, as every ui event requires calling the server. The other option is using a WASM client. In this case the blazor app is downloaded to browser, and runs in the browser. You should use this option if offline access is required.

For the mobile app, you can pick Maui or Blazor Hybrid. Maui uses native controls, so if native look and feel are import pick Maui. Blazor Hybrid uses a webview to host the Blazor Razor Component display, so the UI will match a webapp version.

developing Maui or Blazor Hybrid apps requires a Mac for iPhone/ipad development. You can develop on windows and build on Mac, or just use a Mac for development. But Maui ide support is not the same for a Macs as it is for windows.

Maui / Blazor Hybrid like all cross platform mobile tools, is rather fussy due to platform changes. There is a delay before platform releases and tool updates and the cross platform support. You may be used to only upgrading your build tools on a .net LTS cycle. Mobile development tools have a short LTS cycle than the .net framework. It only 1 year, but platform releases may require code changes in this cycle.

A disadvantage of Maui / Blazor over native tools is not having a visual designer. Both Android and IOS have modern ui libraries with visual designer support.

A mobile alternative is to use a progressive web app written in Blazor WASM.

you have a lot of options, and should review and make your choice on what you are most comfortable with. You should probably try to create a small prototype to determine the best fit.

Given your experience, I'd expect that the learning curve for shifting to cross-platform C# development is shorter than you think. You can entirely stop the practice of building isolated, siloed mobile apps that share nothing but a database. Consider Blazor Hybrid as your framework choice for asset management system.

Microsoft's modern ecosystem organizes frameworks by distinct architectural differences. In a standard Blazor Web project, you build using HTML, CSS, and Razor Components to target web browsers using Server-side execution or WebAssembly. In a pure .NET MAUI project, you target native mobile and desktop operating systems like iOS, Android, Windows, and macOS using XAML and native UI controls, which results in zero code sharing with a web application. Blazor Hybrid acts as the ultimate bridge by allowing you to write your UI once using HTML, CSS, and Razor Components, and then wrapping those web assets inside a native .NET MAUI container called a BlazorWebView. This architecture simultaneously unlocks 100% UI and business logic sharing across mobile, desktop, and web applications.

Blazor Hybrid would be most suitable for your asset management system because it allows you to leverage your existing knowledge of Razor syntax, C#, HTML, and CSS instead of forcing you to learn XAML or foreign mobile ecosystems like Flutter or React Native. You can build your UI components, such as asset cards, management forms, and dashboard elements, inside a single project type known as a Razor Class Library. You then reference this single library from two lightweight entry points: a standard Blazor Web App project for browser users, and a .NET MAUI Blazor Hybrid project that compiles into a native .apk file for Android and a native .ipa file for iOS. Your web and mobile apps will share all of their UI layout, styling, validation logic, and API service classes.

This framework approach handles pretty much every major milestone of your asset management system. For your multi-level authorization and admin section, you can translate your familiarity with classic MVC role-based policies into Blazor's AuthorizeView component and custom AuthenticationStateProvider implementations. Because your business logic is unified in the shared class library, your complex, granular access control rules are written once and fire identically across both desktop browsers and mobile devices.

For your asset architecture dashboards, which rely on interactive tree views, relationship nodes, and vector network graphs, you are not forced to buy specialized, expensive native XAML control suites. Because Blazor Hybrid renders your UI via an internal web view, you can use any standard JavaScript or HTML charting engine, such as D3.js or Chart.js, right out of the box using Blazor’s standard JavaScript Interop. Furthermore, your external system integrations can be handled universally via standard HttpClient calls in your shared C# code. Because a Blazor Hybrid application runs locally as a native application directly on the operating system rather than inside a sandboxed mobile browser, your shared C# code can directly invoke device hardware features like the camera to execute barcode or QR-code scanning for your physical asset tags.
