📝 Walkthrough

Walkthrough

This pull request enhances error handling in the application startup process. The App class constructor is modified to include try-catch blocks for initializing settings, the dependency injection container, and the public API. If exceptions occur, an error message is displayed, and the application exits. A new method, ShowErrorMsgBoxAndFailFast, centralizes error reporting. Additionally, the project file is updated to downgrade the versions of two package references due to compatibility issues.

Changes

File	Change Summary
Flow.Launcher/App.xaml.cs	Added try-catch blocks for settings and DI container initialization; introduced ShowErrorMsgBoxAndFailFast for centralized error handling.
Flow.Launcher/…/Flow.Launcher.csproj	Downgraded Microsoft.Extensions.DependencyInjection (7.0.0 → 6.0.2) and Microsoft.Extensions.Hosting (7.0.0 → 6.0.1) due to TaskScheduler incompatibility.

Poem

I'm a little rabbit, hopping with delight,
In code so robust, everything's set right.
With try-catch hops and error leaps so keen,
I watch for faults where none are seen!
Carrots of code, fresh and true, 🥕
Celebrating changes with a playful "woo-hoo!"

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

I guess probably just upgrade to .net 9 would fix this

[Jack251970]

We should not upgrade the version, but instead we need to downgrade it.

[taooceros]

Task scheduler seems to use 8.0 dependency injection.

yeah if it works then let's go with this first.
