Building cross-platform applications with .NET MAUI Blazor is compelling, but enterprise environments demand careful architectural and performance planning. This session explores how to design MAUI Blazor Hybrid applications that scale across mobile and desktop platforms while delivering native-level responsiveness. Learn how to structure shared libraries, optimize startup time, manage memory, and apply Native AOT and trimming safely. We’ll examine offline-ready designs, authentication strategies, dependency injection patterns, and platform-specific tuning. Through real-world examples and tooling demos, attendees leave with practical guidance for shipping MAUI Blazor apps that meet enterprise reliability, performance, and maintainability expectations.
