Vector

The Dapr.Vector package provides a dedicated .NET client for Dapr’s Vector building block. It supports collection management, vector upserts and retrieval, typed or opaque payloads, metadata filters, query-by-vector or query-by-ID, score thresholds, and ordered batch query results. A bundled source generator can create a typed client bound to a component, collection, and payload type.

These guides target Dapr .NET SDK 1.19.0 or later and Dapr runtime 1.19 or later.

Start with How to: Store and query vectors. For configuration, distance metrics, batch errors, serialization, and generated clients, see the Vector client guidance.

Your application must supply precomputed embeddings; this client does not generate them. For lexical/full-text search over JSON documents, use the Search .NET SDK.
