Starting with UiPath Studio version 2022.10, the default project type is Windows, which uses .NET 6 or .NET
5 with Windows support1. If a project contains dependencies that lack Windows compatibility, such as custom activities or libraries, they are marked as unresolved when the project is converted to Windows2. The developer needs to manually resolve them by finding compatible alternatives or updating the code3.
