✅ CoTaskMemFree on a buffer returned by CsWin32
my code right now looks like this: 
using System.Runtime.InteropServices;
using Windows.Win32;
using Windows.Win32.Foundation;
using Windows.Win32.UI.Shell;

PInvoke.SHCreateItemFromParsingName("shell:::{679f85cb-0220-4080-b29b-5540cc05aab6}", null, typeof(IShellItem).GUID, out var e);
IShellItem shellItem = e as IShellItem;
unsafe
{
    PWSTR pwstr;
    shellItem.GetDisplayName(SIGDN.SIGDN_NORMALDISPLAY, &pwstr);
    string thing = new string((char*)pwstr);
    Console.WriteLine(thing);
    // free pwstr here somehow?
}
using System.Runtime.InteropServices;
using Windows.Win32;
using Windows.Win32.Foundation;
using Windows.Win32.UI.Shell;

PInvoke.SHCreateItemFromParsingName("shell:::{679f85cb-0220-4080-b29b-5540cc05aab6}", null, typeof(IShellItem).GUID, out var e);
IShellItem shellItem = e as IShellItem;
unsafe
{
    PWSTR pwstr;
    shellItem.GetDisplayName(SIGDN.SIGDN_NORMALDISPLAY, &pwstr);
    string thing = new string((char*)pwstr);
    Console.WriteLine(thing);
    // free pwstr here somehow?
}
Marshal.FreeCoTaskMem dosn't accept the pointer to pwstr directly it seems, and trying to use CoTaskMemFree itself results in an access violation
