Migrate VectorStoreRAG and Concepts samples to CommunityToolkit.VectorData packages

[Copilot]

Motivation and Context

Microsoft.SemanticKernel.Connectors.* vector store packages are moving to CommunityToolkit.VectorData.*. This updates the VectorStoreRAG and Concepts sample projects to reference the new package IDs and namespaces.

Description

Package reference updates (Directory.Packages.props, VectorStoreRAG.csproj, Concepts.csproj):

Old	New	Version
Microsoft.SemanticKernel.Connectors.AzureAISearch	CommunityToolkit.VectorData.AzureAISearch	1.0.0
Microsoft.SemanticKernel.Connectors.CosmosMongoDB	CommunityToolkit.VectorData.CosmosMongoDB	1.0.0
Microsoft.SemanticKernel.Connectors.CosmosNoSql	CommunityToolkit.VectorData.CosmosNoSql	1.0.0
Microsoft.SemanticKernel.Connectors.InMemory	CommunityToolkit.VectorData.InMemory	1.0.0
Microsoft.SemanticKernel.Connectors.PgVector	CommunityToolkit.VectorData.PgVector	1.0.0
Microsoft.SemanticKernel.Connectors.Qdrant	CommunityToolkit.VectorData.Qdrant	1.0.0
Microsoft.SemanticKernel.Connectors.Redis	CommunityToolkit.VectorData.Redis	1.0.0
Microsoft.SemanticKernel.Connectors.Weaviate	CommunityToolkit.VectorData.Weaviate	1.0.0

Namespace updates :

// Before
using Microsoft.SemanticKernel.Connectors.InMemory;
// After
using CommunityToolkit.VectorData.InMemory;

DI extension methods (AddInMemoryVectorStore, AddQdrantCollection, etc.) moved to Microsoft.Extensions.DependencyInjection in the CT packages — all affected files already had that using, so no additional changes needed there.

API compatibility fixes:

• [VectorStoreVector(Dimensions: N)] → [VectorStoreVector(N)] in two files — the new Microsoft.Extensions.VectorData.Abstractions constructor uses a positional parameter named dimensions (lowercase), so the old named-argument form no longer compiles.
• SharpCompress pin bumped 0.48.0 → 0.48.1 in Directory.Packages.props — CommunityToolkit.VectorData.CosmosMongoDB pulls MongoDB.Driver 3.10.0 which requires >= 0.48.1.
• Added <AzureCosmosDisableNewtonsoftJsonCheck>true</AzureCosmosDisableNewtonsoftJsonCheck> to both sample csproj files — CommunityToolkit.VectorData.CosmosNoSql pulls Microsoft.Azure.Cosmos 3.61.0 which added a mandatory Newtonsoft.Json explicit-reference check not present in the prior version.

Contribution Checklist

make sure that none of the projects in this repo keeps using Microsoft.SemanticKernel.Connectors.* packages, just migrate all of them to CommunityToolkit.VectorData.*

[Copilot]

Copilot fix following build failure:

Fixed in the latest commit. All 6 failing projects have been migrated:

• GettingStartedWithVectorStores, GettingStartedWithTextSearch, OnnxSimpleRAG, MCPServer, ChatWithAgent.ApiService — PackageReferences updated to CommunityToolkit.VectorData.* and using statements updated in the corresponding .cs files.
• SemanticKernel.UnitTests — converted from a PackageReference to a ProjectReference to the local src/VectorData/InMemory project (which keeps the Microsoft.SemanticKernel.Connectors.InMemory namespace, so no using changes were needed in the test files).

Pull request overview

Updates the .NET VectorStore/RAG and text search ecosystem to use the new CommunityToolkit.VectorData.* connector packages (instead of Microsoft.SemanticKernel.Connectors.*) across samples and tests, alongside dependency/version alignment and minor API-compat fixes in SemanticKernel.Core.

Changes:

• Switch multiple samples/tests from Microsoft.SemanticKernel.Connectors.* packages/namespaces to CommunityToolkit.VectorData.*.
• Update central package versions (including MongoDB.Driver and Microsoft.Extensions.VectorData.Abstractions) and remove explicit SharpCompress/Snappier pinning in connector projects.
• Apply compatibility fixes: add where TRecord : class constraints and add package-validation suppressions; update [VectorStoreVector(...)] usage in samples.

• The Pinecone Langchain interop scenario appears to have been removed (along with the PineconeFactory), but the PR description indicates Pinecone should be migrated to CommunityToolkit.VectorData.Pinecone. If Pinecone interop is still in scope, consider reintroducing this example using the new CT package; otherwise, update the PR description / sample narrative to reflect the dropped Pinecone scenario.
