Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a proactive unit test designed to detect duplicate GUIDs among plugin types. By validating the uniqueness of these identifiers, the change helps prevent potential runtime conflicts and ensures better stability during future merges.

Highlights

• New Validation Test: Added a new test case, AllPluginTypesHaveUniqueGuids, to ensure that all types decorated with the PlugInAttribute maintain unique GUIDs.
• Dependency Updates: Included necessary using statements for System.Reflection and MUnique.OpenMU.PlugIns to support the new validation logic.

Code Review

This pull request introduces a new unit test, AllPluginTypesHaveUniqueGuids, in PlugInManagerTest.cs to ensure that all plugin types decorated with PlugInAttribute have unique GUIDs. The reviewer suggested refactoring the test to use PlugInManager for discovering and registering plugins instead of querying AppDomain.CurrentDomain.GetAssemblies() directly, which avoids potential reflection-related exceptions and aligns with runtime plugin loading behavior.

Code Review

This pull request introduces duplicate GUID validation during plugin discovery and registration by adding a new validation method and a custom exception. It also refactors several logging statements to use structured logging instead of string interpolation. The feedback highlights that the validation is currently static and only checks the newly discovered plugins, meaning it will miss conflicts with already registered plugins. It is recommended to make the validation method an instance method, check against existing plugins, and handle potential null values for FullName.
