Research direction

The issue names no files, tests, or entry points. Start by locating EF Core's IndexAttribute conventions and related tests, then determine how property-level attributes should create a single-column index while preserving the existing class-level behavior.

Written by the indexing model from the issue text.

Description

area-model-building needs-design

The EF Core 5.0 IndexAttribute is designed to be placed at the class level, rather than on individual properties. This aligns the definition of composite and single column indexes and avoids confusion about whether or not two columns form a single composite index or two single column indexes.

However, this means that it is not possible to put a simple attribute on a property to create a simple single column index on the mapped column. This issue is on the backlog to gather feedback on the level of demand for this feature.
