Description

We are using CreateRestrictedToken together with WindowsIdentity.RunImpersonatedAsync, but this leads to a problem: WindowsIdentity.RunImpersonatedAsync expects a SafeAccessTokenHandle but CreateRestrictedToken returns a SafeFileHandle.

Would it make sense to change the out parameter of CreateRestrictedToken to SafeAccessTokenHandle?

Thanks in advance!

Research direction

Start by tracing how CreateRestrictedToken is generated and compare its returned handle type with the SafeAccessTokenHandle required by WindowsIdentity.RunImpersonatedAsync. Check the relevant generator tests, if present, and verify that the generated declaration supports the intended impersonation call without breaking existing uses.
