Important
The experimental channel is not supported for use in production environments, and apps that use the experimental releases cannot be published to the Microsoft Store.
The experimental channel includes releases of the Windows App SDK with experimental channel features in early stages of development. APIs for experimental features have the Experimental attribute. If you call an experimental API in your code, you will receive a build-time warning. All APIs in the experimental channel are subject to extensive revisions and breaking changes. Experimental features and APIs may be removed from subsequent releases at any time.
Important links:
- If you'd like to upgrade an existing app from an older version of the Windows App SDK to a newer version, see Update existing projects to the latest release of the Windows App SDK.
- For documentation on experimental releases, see Install tools for preview and experimental channels of the Windows App SDK.

The underlying ML models required for these APIs currently require your device to be running the latest Windows 11 Insider Preview Build on the Dev Channel. Additionally, these APIs require your device to be a Copilot+ PC. See Copilot+ PCs Developer Guide to learn more about these devices. APIs will throw an exception when called on devices lacking the necessary support.
The Windows Copilot Runtime (WCR) offers several AI-powered features and APIs for you to easily, efficiently, and responsibly use on-device AI models in your Windows apps. In this release we are making available several scenario focused APIs for you to leverage powerful capabilities without the need to find, run, or optimize your own Machine Learning (ML) models.
Learn more about responsible development practices used during WCR API development that you can also apply as you create AI-assisted features in the Developing Responsible Generative AI Applications and Features on Windows guidance.
This is the latest release of the experimental channel.
To download, retarget your WinAppSDK NuGet version to 1.8.250410001-experimental1.
The ImageObjectRemover can be used to remove objects from images. The model takes both an image and a greyscale mask indicating the object to be removed, erases the masked area from the image, and replaces the erased area with the image background.
This release includes the following new and modified experimental APIs:
