Important

This release has Known Issues visit our release notes for more information.

The Windows App SDK incorporates advanced Windows AI capabilities, enabling developers to seamlessly integrate intelligent features into their applications. These enhancements include local AI functionalities such as:

• Summarize Conversation feature that allows you to summarize what people have said over an email, chat, or thread. See Phi Silica for more details
• Low-Rank Adaption (LoRA) for Phi Silica allows developers to fine-tune the on-device language model (Phi Silica) using their own custom data.

This release also include the following:

• Decimal support which offers a high-precision base-10 numeric data type that is invaluable for financial and scientific calculations, avoiding imprecision and rounding errors inherent to floating-point data types.
• The Windows App SDK NuGet package has been converted to a NuGet metapackage. The use of individual component packages enables developers to include only the APIs and functionalities that are necessary for their apps.
• The MSIX publishing support has been factored into a standalone nuget package, which can be independently maintained and consumed by Windows App SDK and other projects.
• In addition, several feature gaps with Single-Project solutions have been addressed including generation of MSIX bundles and MSIX upload packages.
