Microsoft introduces experimental support for ARM64’s, a SIMD instruction set, within the .NET runtime. A new compiler optimization, dubbed an “energy-efficient loop” feature, has been introduced, offering a notable “runtime savings” in loops. With this functionality, the loop operation has been replaced by a more efficient, logically equivalent operation, consistent with best practices. With the release of .NET 6 Preview 7, the runtime now has automatic globalization (ALG) enabled by default.

With the Software Development Kit (SDK), advancements have been made to simplify container publication for insecure registries, while also providing additional environmental constants that streamline the publishing process. The preview also introduces workload units’ first release, a software development kit (SDK) feature that provides customers with greater control over the workloads they configure and the pace of updates for installed workloads.

Among numerous library enhancements, the eradication of BinaryFormatter is full. The deserialization process was terminated due to its inefficiency. Additionally, the preview the X509CertificateLoader Class, which consolidates numerous “content-sniffing” approaches into a single, streamlined methodology driven by a clear objective. In one other change, the System.IO.Compression APIs now use zlb-ngenabling sustainable and consistent performance across a broader range of hardware configurations and operating systems.
