With Entity Framework Core 10, the next version of the object-relational mapper, a new default translation mode is introduced for parameterized collections, where each value in the collection is translated into its own scalar parameter. This allows collection values to change without resulting in different SQL code, which results in cache misses and other performance problems, Microsoft said.
Also introduced in .NET 10 Preview 7 is WebSocketStream, an API designed to simplify common WebSocket scenarios in .NET. Traditional WebSocket APIs are low-level and require significant boilerplate for tasks such as handling buffering and framing and managing encoding and decoding, Microsoft said. These complexities make it difficult to use WebSockets as a transport, especially for apps with streaming or text-based protocols. WebSocketStream addresses these issues by providing a Stream-based abstraction over a WebSocket, enabling seamless integration with existing APIs.
