# ProcessService

> *This is an experimental feature.* The ProcessService allows you to start slave instance of UnityEditor, opened to the same Project as the master instance, with a specific RoleProviderAttribute.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.MPE](/engine/6000.6/script-reference/unityeditor/mpe.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public class ProcessService

## Remarks

The Standalone Profiler workflow uses this technology.
