Cross-Platform Development: C#, Azure, Flutter, and Web UIs

Design a single C# backend (e.g., ASP.NET Core Web API) that serves both mobile (Flutter) and web (Angular/React) clients. Implement shared business logic, data access layers, and authentication/authorization. Focus on creating a robust, versioned API that can be consumed by diverse frontend applications.

Use MS SQL Server as the centralized data store for all your applications. This ensures data consistency across mobile and web platforms. Implement robust data validation and integrity checks at the database level. Consider using stored procedures for complex data operations accessible by the C# backend.

Host your C# backend on Azure App Service or Azure Container Apps. Utilize Azure API Management to secure, publish, and manage APIs for both mobile and web clients. Explore Azure Notification Hubs for push notifications to Flutter apps and Azure Blob Storage for media assets shared across platforms.

Develop a sophisticated web application with Angular, perhaps an admin panel or a Progressive Web App (PWA), that interacts with the shared C# backend. Angular's comprehensive framework is well-suited for complex enterprise web solutions, providing structured development for your web-based interfaces.

Build a dynamic web client or a data dashboard with React that consumes the same C# backend. React's component-based approach allows for flexible UI development, making it ideal for creating interactive web experiences that complement your mobile applications.

Develop beautiful, natively compiled applications for mobile (iOS and Android) from a single codebase using Flutter. Connect your Flutter app to the C# backend via HTTP requests. Leverage Flutter's rich widget library and reactive UI paradigm to deliver a consistent user experience across devices.
