Description

Windows 11 SDK has support for setting a process to use the efficiency cores for Windows 11 on 12th Generation Intel Core i7 processors

https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setprocessinformation

Is it possible for .net to set a priority of process to use the execution cores?

Describe the solution you'd like

Add a enumerator value to ProcessPriorityClass, BasePriority that tells the scheduler to use efficiency cores if available.

Contributor guide
