# Project compatibility

> Pipelines activity package compatibility with project types in UiPath Studio.

Here you can verify the compatibility of the package and the activities included in it with the project types available in Studio.

| Activity Package | Windows - Legacy | Windows | Cross-platform |
| --- | --- | --- | --- |
| UiPath.Pipelines.Activities | ❌ | ✅ | ✅ |

Here you can verify the compatibility between the package version, the required.NET version, and the target Robot version.

| UiPath.Pipelines.Activities | .NET version required | Target Robot version for the built automations |
| --- | --- | --- |
| 1.0.x | .NET 6 | 2023.6+ |
| 2.0.x | .NET 6 | 2023.10+ |
| 3.0.x | .NET 8 | 2024.10+ |

:::note
There is a compatibility requirement between the automation projects you intend to build and the machine that runs the pipeline process. The correct mapping is:
* Windows-Legacy project → Build OS: Windows only
* Windows project→ Build OS: Windows only
* Cross-Platform project→ Build OS: Windows or Linux
