.NET MAUI MSAL (Microsoft Entra ID) Sign-In + Microsoft Graph

I have a .NET MAUI app (tabs, pages done) with MSAL already integrated. Interactive sign-in works (AAD prompt appears, I can authenticate), but when it returns to the app it lands back on the Login page and spins instead of navigating into the app. I need a MAUI/MSAL expert to finish the handoff and prove the session by calling Microsoft Graph /me. What’s already done MAUI app (.NET 8/9) with Shell & pages (Home, Timetable, etc.) MSAL wired (PublicClientApplication, redirects, Android manifest) Sign-in launches and completes; tokens appear to be acquired What I need Diagnose & fix the post-login flow so, after successful auth, the app: navigates to AppShell/Home, and displays basic Graph /me info (DisplayName/UPN) as proof. Add a clean silent sign-in on app start. Keep Android stable (embedded webview preferred) and ensure WithParentActivityOrWindow is correct. Minimal notes for iOS/Windows redirects (no deep work required there). Deliverables Working handoff (Login → Shell) with a small “Signed in as …” label populated from /me. IAuthService methods: silent, interactive, token retrieval, sign-out. Short README: redirects used, where to change ClientId, how to test. Acceptance Tap Sign in → authenticate → app shows “Signed in as …” then lands on Home. Relaunch app → silent sign-in succeeds (no prompt). GetAccessTokenAsync("User.Read") returns a valid token. Works on Android emulator/device. (iOS/Windows basic check is a bonus.) Tech .NET MAUI (.NET 8/9), Microsoft.Identity.Client v5, Graph SDK v5. Azure App Registration & permissions (User.Read) already set up. What I’ll provide Repo access, ClientId/TenantId, and current auth code. Please include: Briefly how you’ll fix the handoff (embedded vs system browser, parent activity). A link or snippet showing prior MSAL on MAUI/Xamarin work. Your fixed price & earliest start.

Seeking Experienced Xamarin & MAUI Developer for Migration Work

We are looking for a highly experienced freelance developer to lead the migration of a long-standing mobile application from Xamarin.Forms to .NET MAUI. With Xamarin being deprecated, this project is essential to ensure the app remains functional, supported, and maintainable. The ideal candidate must have a strong background in both Xamarin and MAUI, with proven experience migrating or building production-grade apps using both platforms. Evidence of past work or relevant case studies will be required. The original developer, who built and maintained the app over the past six years and has now transitioned to MAUI, will be available to oversee the project and provide guidance where needed. This ensures continuity and technical insight throughout the migration process. The migration plan includes setting up a new MAUI environment, aligning the project structure with MAUI standards, updating UI components, converting custom renderers, refactoring platform-specific code, and implementing the MAUI MVVM Community Toolkit. This is a time-critical project that needs to begin immediately, and we're looking for someone who can hit the ground running. There is also potential for continued development work following successful completion of the migration.
