Mandatory parent window handle configuration for WAM authentication

6

Starting with MSAL 4.52+, developers must explicitly specify parent window handles using WithParentActivityOrWindow APIs for Windows broker (WAM) authentication. Omitting this causes poor UX where auth windows hide behind the application, and window inference is no longer feasible.

Platform-specific WAM limitations and fallback handling

6

Windows Broker (WAM) implementation has significant limitations: B2C and ADFS authorities aren't supported, it only works on Windows 10+ and Server 2019+, and older platforms must fall back to browser-based authentication. Developers must handle these constraints in multi-platform applications.
