Unable to deploy WebPart to SharePoint SE from Visual Studio 2019 or 2022

Hi sbajda,

The error message "A task was canceled" usually indicates that the deployment process was interrupted or canceled by the user or by the system. There could be multiple reasons for this issue. I am listing few steps to resolve the issue:

1. Restart Visual Studio and try to deploy the project again.

2. Try to deploy the project on a different environment, such as a local development machine or a test server, to see if the issue is specific to the current environment.

3. Check the SharePoint logs for any errors related to the deployment process. The logs can be found in the SharePoint server's Event Viewer, or you can use the ULS Viewer to view the logs in a more readable format.

4. Make sure that the SharePoint server and IIS are configured correctly and that you have the necessary permissions to deploy the project.

5. If the issue persists, try to remove the Visual Webpart from the project and add it again. You can also try to create a new SharePoint project and add the Visual Webpart to it, and see if the issue is specific to the current project.
