Rename EventingExtensions class to DistributedApplicationEventingExtensions

[Copilot]

This PR renames the EventingExtensions class to DistributedApplicationEventingExtensions to provide a more descriptive and specific name that clearly indicates its purpose and scope within the Aspire hosting framework.

Changes Made

• Class Rename: Changed class definition from EventingExtensions to DistributedApplicationEventingExtensions in the source file
• File Rename: Renamed the file from EventingExtensions.cs to DistributedApplicationEventingExtensions.cs to match the new class name

Impact

This is a non-breaking change for consumers of the library because:

• All extension methods (OnBeforeResourceStarted, OnConnectionStringAvailable, OnInitializeResource, OnResourceEndpointsAllocated, OnResourceReady) remain functionally identical
• Extension methods are accessed by their method names, not the class name that contains them
• Existing code using these extension methods will continue to work without any modifications
• The class is only used internally by the C# compiler for method resolution

Verification

• ✅ All builds pass successfully after the rename
• ✅ Existing tests that use the extension methods continue to work without modification
• ✅ No references to the old class name remain in the codebase
• ✅ Build artifacts and XML documentation now correctly reference the new class name

The new name DistributedApplicationEventingExtensions better reflects that these are extension methods specifically for distributed application resource eventing, making the codebase more maintainable and self-documenting.

This pull request was created as a result of the following prompt from Copilot chat.

Rename the extension method class EventingExtensions to DistributedApplicationEventingExtensions in Aspire 9.4.

Tasks:

1. Class Rename: Rename the class definition from EventingExtensions to DistributedApplicationEventingExtensions in src/Aspire.Hosting/EventingExtensions.cs.
2. File Rename: Rename the file from EventingExtensions.cs to DistributedApplicationEventingExtensions.cs to match the new class name.
3. Reference Updates: Update all references to EventingExtensions throughout the codebase to use DistributedApplicationEventingExtensions instead (including all usages, using static statements, or comments if present).
4. Project/Build File Update: If the renamed file is referenced explicitly in a project/build file, update its path/name accordingly.
5. Test/Validate: Ensure no references to the old class name remain and that all documentation and usages reflect the new class name.

Note: Only the first 10 search results were available for direct reference. Please ensure a comprehensive search for all usages of the old class name.

Pull Request Overview

This PR renames the EventingExtensions class to DistributedApplicationEventingExtensions to provide a more descriptive and specific name that clearly indicates its purpose for distributed application resource eventing within the Aspire hosting framework.

Key Changes:

• Renamed class from EventingExtensions to DistributedApplicationEventingExtensions
• Renamed corresponding file to match the new class name
• Maintained all existing extension method functionality

Comments suppressed due to low confidence (1)

src/Aspire.Hosting/DistributedApplicationEventingExtensions.cs:12

• [nitpick] The new class name DistributedApplicationEventingExtensions is quite long and may impact readability. Consider a more concise alternative like DistributedAppEventingExtensions or AppEventingExtensions while still maintaining clarity about its purpose.

public static class DistributedApplicationEventingExtensions

LGTM

/backport to release/9.4

[github-actions]

Started backporting to release/9.4: https://github.com/dotnet/aspire/actions/runs/16559154000

[davidfowl]

This would need to be in 9.4 since this is not experimental.

[mitchdenny]

Yep backporting now.
