Updates the out-of-the-box Vector Store connector docs for the C# connectors (CommunityToolkit.VectorData).

Connector list changes

  • Remove the Pinecone .NET connector (the .NET SDK was archived) and Neon from the C# tables. The Python entries are unchanged.
  • Add a dedicated Chroma connector page and mark Chroma as supported (CommunityToolkit.VectorData.Chroma, preview). See Chroma: add the MEVD provider CommunityToolkit/AI#58
  • Set ".NET Community Toolkit" as the vendor for the C# providers.
  • Rename "Azure CosmosDB NoSQL" to "Azure CosmosDB" and "Azure CosmosDB MongoDB" to "Azure DocumentDB". File names are unchanged, so existing links keep working.
  • Remove the preview warning from the stable C# connectors. Only Chroma and SQLite (SqliteVec) are still preview on nuget.org.

Accuracy fixes, validated against https://github.com/CommunityToolkit/AI/tree/main/MEVD/src

  • Replace the legacy AnyTagEqualTo/EqualTo filter rows with LINQ expression support, noting provider-specific limits.
  • Correct the supported key and data types, index kinds, distance functions and defaults.
  • Correct the IsIndexed, IsFullTextIndexed and HybridSearch rows (Postgres, SQL Server, SQLite).
  • Cosmos: PartitionKeyPropertyName is now PartitionKeyProperties, RecordKey is now DocumentId, and the partition key sample uses CosmosCollection<CosmosKey, Hotel>.
  • DocumentDB: update the namespace and types (DocumentDBVectorStore, AddDocumentDBVectorStore).
  • Fix samples that wouldn't compile or run: unsupported ulong keys, mismatched collection key types, a missing comma, an unsupported Weaviate index kind, Qdrant https defaults, and SQLite DDL.
  • Remove duplicated DI snippets, and add short notes on DI overloads and IEmbeddingGenerator pickup.

Python and Java content is unchanged.

The .NET API reference still shows the old Chroma connector, with no note that it is deprecated: https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel.connectors.chroma.chromaclient?view=semantic-kernel-dotnet (Microsoft.SemanticKernel.Connectors.Chroma 1.45.0-alpha, which calls the v1 API that Chroma 1.x no longer serves). The package on NuGet already suggests CommunityToolkit.VectorData.Chroma. Could the reference point there too? Its source is in a private repository, so I could not open a PR.
