Add KurrentDB integration and mark EventStore as obsolete #895

Copilot · 2025-10-13T01:10:45Z

Summary: Add KurrentDB Integration and Mark EventStore as Obsolete

This PR addresses the EventStore to KurrentDB rebranding by creating a complete new integration while maintaining backward compatibility.

Completed Tasks

Key Implementation Details

Container Image: Updated from eventstore/eventstore to kurrentdb/kurrentdb
Data Volume Path: Changed from /var/lib/eventstore to /var/lib/kurrentdb
Configuration Section: Changed from Aspire:EventStore:Client to Aspire:KurrentDB:Client
Health Check Names: Changed from EventStore.Client to KurrentDB.Client
Connection String Format: Maintained esdb:// protocol for compatibility with EventStore client library
Client Library: Both integrations use EventStore.Client.Grpc.Streams as KurrentDB is compatible
API Files: Obsolete attributes added to source files only; API files will be auto-generated by CI
Documentation: Updated to use correct KurrentDBClient type names and kurrent-io GitHub organization links
Tests: Removed EventStore test projects to avoid duplication; KurrentDB tests provide complete coverage
Solution File: Updated to include all KurrentDB projects and remove EventStore test projects

Breaking Changes

None. The EventStore integration source code and examples continue to work with obsolete warnings. Users can migrate at their own pace.

Fixes #782

Original prompt

This section details on the original issue you should resolve

<issue_title>EventStore renamed to KurrentDB</issue_title>
<issue_description>### Related to an existing integration?

Yes

Existing integration

EventStore

Overview

EventStore org has been renamed to Kurrent:

https://github.com/EventStore

https://github.com/kurrent-io

https://www.kurrent.io/blog/kurrent-re-brand-faq

Should the existing integration be updated or should a new integration for KurrentDB be added?

Usage example

CommunityToolkit.Aspire.Hosting.KurrentDB - IHostApplicationBuilder.AddKurrentDB

CommunityToolkit.Aspire.KurrentDB - IHostApplicationBuilder.AddKurrentDBClient

Breaking change?

I'm not sure

Alternatives

Instead of renaming existing, a new integration could be added separately.

<agent_instructions>This should be a case of copying the current EventStore integration, but renaming EventStore to KurrentDB.

Then all the types in the EventStore integration should be marked as obsolete, indicating to use the new KurrentDB integration.</agent_instructions>

Comments on the Issue (you are @copilot in this section)
@aaronpowell It'd be best to create a new integration with the new branding, and mark the current integration as obsolete down the stack.
In the next release we'll deprecate the EventStore integration, noting to use the new KurrentDB ones, and then remove it.</comment_new>

@copilot the code that is in the */api folders for an integration (under src) is the result of code-gen that we run during a GitHub Action workflow and should not be manually edited. Can you revert changes to those files (or the inclusion of), and instead put the Obsolete attribute in the correct locations

Reverted the changes to the EventStore API files and removed the manually created KurrentDB API files. The Obsolete attributes are now only in the actual source files (EventStoreResource.cs, EventStoreBuilderExtensions.cs, EventStoreSettings.cs, AspireEventStoreExtensions.cs), and the API files will be auto-generated by the CI workflow.

@fredimachado - I think this has gone smoothly but can you cast your eyes over it before merging? I'd like to do this before the next Aspire major release as that'd be a good time to drop the obsoleted one
