[MS] Azure SDK Release (April 2026) - devamazonaws.blogspot.com

Thank you for your interest in the new Azure SDKs! We release new features, improvements, and bug fixes every month. Subscribe to our Azure SDK Blog RSS Feed to get notified when a new release is available. You can find links to packages, code, and docs on our Azure SDK Releases page.

Release highlights

Cosmos DB 4.79.0

The Java Cosmos DB library includes a critical security fix for a Remote Code Execution (RCE) vulnerability (CWE-502). Java deserialization was replaced with JSON-based serialization in CosmosClientMetadataCachesSnapshot, AsyncCache, and DocumentCollection, eliminating the entire class of Java deserialization attacks. This release also adds support for N-Region synchronous commit, a Query Advisor feature, and CosmosFullTextScoreScope for controlling BM25 statistics scope in hybrid search queries.

AI Foundry 2.0.0

The Azure.AI.Projects NuGet package ships its 2.0.0 stable release with significant architectural changes. Evaluations and memory operations moved to separate Azure.AI.Projects.Evaluation and Azure.AI.Projects.Memory namespaces. Many types were renamed for consistency, including Insights → ProjectInsights, Schedules → ProjectSchedules, Evaluators → ProjectEvaluators, and Trigger → ScheduleTrigger. Boolean properties now follow the Is* naming convention, and several internal types were made internal.

AI Agents 2.0.0

The Java Azure AI Agents library reaches general availability with version 2.0.0. This release includes breaking changes to improve API consistency:
  • Several enum types were converted from standard Java enum to ExpandableStringEnum-based classes.
  • *Param model classes were renamed to *Parameter.
  • MCPToolConnectorId now uses consistent casing as McpToolConnectorId.
  • A new convenience overload for beginUpdateMemories was added.

[MS] Pulling a single item from a C++ parameter pack by its index, remarks - devamazonaws.blogspot.com

In my earlier discussion of pulling a single item from a C++ parameter pack by its index , I noted that with the Pack Indexing proposal, you would be able to write this to pull an item from a parameter pack while preserving its reference category. template<int index, typename...Args> void example(Args&&... args) { auto&& arg = (Args...[index]&&)args...[index]; using Arg = Args...[index]&&; } Why did I need to apply the (Args...[index]&&) cast ? Why can't I just write this: auto&& arg = args...[index]; or possibly decltype(auto) arg = args...[index]; Well, when you write the name of a variable, the result is an lvalue reference, even if the variable is an rvalue reference . Watch: struct S { S(S&); // construct from lvalue S(S&&); // construct from rvalue }; void whathappens(S&& s) { S t = s; // which will it use? } Try it out in your favorite compiler. This code construc...

[MS] Going beyond the empty set: Embracing the power of other empty things - devamazonaws.blogspot.com

The empty set contains nothing. This sounds really silly, but it's actually really nice. The Windows Runtime has a policy that if a method returns a collection (such as an IVector ), and the method produces no results, then it should return an empty collection, rather than a null reference . That way, consumers can just iterate over the collection without having to deal with a null test. For example, suppose you have a method Widget:: Get­Associated­Doodads which returns an IVectorView<Doodad> representing the Doodad objects that have been associated with a Widget object. If no Doodad s have been associated with the Widget , then it should return an empty vector, not a null pointer. That allows developers to write the natural-looking code: // C# foreach (var doodad in widget.GetAssociatedDoodads()) { ⟦ process each doodad ⟧ } // C++/WinRT for (auto&& doodad : widget.GetAssociatedDoodads()) { ⟦ process each doodad ⟧ } // JavaScript widget.GetAssociated...
