PWA Not Loading Offline After Publishing in .NET MAUI Blazor App

[faisalkkv]

Description:
When debugging the .NET MAUI Blazor app, the PWA loads and works offline as expected. However, after publishing the app, the PWA does not load offline.

Steps to Reproduce:

Create a .NET MAUI Blazor app.
Load the PWA app from an external URL using an <iframe>.
Debug the project:

• First, run the app while online. Verify that the PWA app loads as expected.
• Then switch to offline mode. Verify that the PWA app continues to work offline as expected.

Publish the app (e.g., using dotnet publish with the appropriate configurations).
Test the published app:

• While online, the PWA app works as expected.
• Switch to offline mode. The PWA app fails to load.

Expected Behavior:
The PWA should load and function offline after being published, as it does during debugging.

Actual Behavior:
The PWA does not load offline after publishing.
