Eclipse aCute is a nice project to develop C# using Language Server and Debug Adapters, receiving ~600 Marketplace installation monthly.
However, we (Red Hat Eclipse IDE developers) initiated it at the beginning of Language Servers, more as a successful technical proof of concept and as a less successful tentative to fish C# developers into Eclipse IDE; without a real long-term strategy for the project.
So we're going to stop fully our work on aCute. If anyone wants to take the lead, we'd be delighted to help for a smooth transition. If no-one claims further interest in maintaining it relatively soon, we'll ask Foundation to archive the project.
