API for Windows 10 virtual desktops [duplicate]

Question

I love that Windows 10 now has support for virtual desktops built in, but I have some features that I'd like to add/modify (e.g., force a window to appear on all desktops, launch the task view with a hotkey, have per-monitor desktops, etc.)

I have searched for applications and developer references to help me customize my desktops, but I have had no luck.

Where should I start? I am looking for Windows API functions (ideally, that are callable from a C# application) that will give me programmatic access to manipulate virtual desktops and the windows therein.

The Windows SDK Support Team Blog posted a C# demo to switch Desktops via IVirtualDesktopManager:

[ComImport, InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("a5cd92ff-29be-454c-8d04-d82879fb3f1b")] [System.Security.SuppressUnmanagedCodeSecurity] public interface IVirtualDesktopManager { [PreserveSig] int IsWindowOnCurrentVirtualDesktop(     [In] IntPtr TopLevelWindow,     [Out] out int OnCurrentDesktop     ); [PreserveSig] int GetWindowDesktopId(     [In] IntPtr TopLevelWindow,     [Out] out Guid CurrentDesktop     );  [PreserveSig] int MoveWindowToDesktop(     [In] IntPtr TopLevelWindow,     [MarshalAs(UnmanagedType.LPStruct)]     [In]Guid CurrentDesktop     ); }  [ComImport, Guid("aa509086-5ca9-4c25-8f95-589d3c07b48a")] public class CVirtualDesktopManager {  } public class VirtualDesktopManager {     public VirtualDesktopManager()     {         cmanager = new CVirtualDesktopManager();         manager = (IVirtualDesktopManager)cmanager;     }     ~VirtualDesktopManager()     {         manager = null;         cmanager = null;     }     private CVirtualDesktopManager cmanager = null;     private IVirtualDesktopManager manager;      public bool IsWindowOnCurrentVirtualDesktop(IntPtr TopLevelWindow)     {         int result;         int hr;         if ((hr = manager.IsWindowOnCurrentVirtualDesktop(TopLevelWindow, out result)) != 0)         {             Marshal.ThrowExceptionForHR(hr);         }         return result != 0;     }      public Guid GetWindowDesktopId(IntPtr TopLevelWindow)     {         Guid result;         int hr;         if ((hr = manager.GetWindowDesktopId(TopLevelWindow, out result)) != 0)         {             Marshal.ThrowExceptionForHR(hr);         }         return result;     }      public void MoveWindowToDesktop(IntPtr TopLevelWindow, Guid CurrentDesktop)     {         int hr;         if ((hr = manager.MoveWindowToDesktop(TopLevelWindow, CurrentDesktop)) != 0)         {             Marshal.ThrowExceptionForHR(hr);         }     } } 

it includes the API to detect on which desktop the Window is shown and it can switch and move a Windows the a Desktop.
