## Add Out-of-Proc Trace Support for Activity Events and Links

The .NET [Activity](https://learn.microsoft.com/dotnet/api/system.diagnostics.activity) class enables distributed tracing by tracking the flow of operations across services or components. .NET supports serializing this tracing data out-of-process via the `Microsoft-Diagnostics-DiagnosticSource` event source provider.

An Activity can include additional metadata such as [ActivityLink](https://learn.microsoft.com/dotnet/api/system.diagnostics.activitylink) and [ActivityEvent](https://learn.microsoft.com/dotnet/api/system.diagnostics.activityevent). We’ve added support for serializing these as well, so out-of-proc trace data can now include information representing links and events, like the following:

## Full-text search support on Azure Cosmos DB for NoSQL

Azure Cosmos DB now offers support for [full-text search](/azure/cosmos-db/gen-ai/full-text-search). It enables efficient and effective text searches, as well as evaluating the relevance of documents to a given search query. It can be used in combination with vector search to improve the accuracy of responses in some AI scenarios.
EF Core 10 is adding support for this feature allowing for modeling the database with full-text search enabled properties and using full-text search functions inside queries targeting Azure Cosmos DB.

Here is a basic EF model configuration enabling full-text search on one of the properties:
