In this Grid every child is added without Grid.Row/Grid.Column attached properties; in MAUI they all default to row 0/column 0, so the four sample action buttons overlap and only the topmost one is usable. This affects the sample UI when launched on any target and prevents users from reaching most of the demonstrated actions.

Adds a new .NET MAUI sample application (samples/Exceptionless.SampleMaui) demonstrating how to use the core Exceptionless client from a MAUI app via DI, including local file-based queue storage and file logging.
Changes:
- Introduces a MAUI sample app with a simple UI for sending handled exceptions, warning logs, feature usage, and flushing the queue.
- Adds platform-specific bootstrap files/manifests (Android/iOS/Mac Catalyst/Windows) plus app icon and splash resources.
- Registers the new sample project in
Exceptionless.Net.slnxunder the Samples folder.

There was a problem hiding this comment.
When a handled exception has already been submitted, this returns that exception's id for the warning log because SubmitLog does not assign a ReferenceId, and GetLastReferenceId() is only updated for events that already have one. The autorun flow always submits the handled exception first, so logReferenceId and the same pattern in TrackFeatureUsage can point at the wrong event even though the log/usage events were queued; generate and set a reference id on those event builders before returning it.
