Hmm, CreateProcess gives error 87 - The Parameter is Incorrect - the reason I'm even trying to do all this is that I'm trying to reimplement https://scorpiosoftware.net/2019/01/15/fun-with-appcontainers/ in C# to play around with AppContainers...

Ah, got it working: PInvoke.CreateProcess(null, cmdLine, null, null, false, PROCESS_CREATION_FLAGS.EXTENDED_STARTUPINFO_PRESENT, null, null, (STARTUPINFOW*)&info, procInfoPtr);

(Can't convert STARTUPINFOEXW to STARTUPINFOW etc.)

This feels like it should work: 
string execPath = "notepad.exe\0";
nuint* size = default;
PInvoke.InitializeProcThreadAttributeList(default, 1, 0, size);
STARTUPINFOEXW info = new STARTUPINFOEXW();
info.lpAttributeList = (LPPROC_THREAD_ATTRIBUTE_LIST)Windows.Win32.PInvoke.LocalAlloc(0, (nuint)size).Value;
fixed (char* cmdLine = execPath)
{
  PROCESS_INFORMATION* procInfoPtr = default;
  PInvoke.CreateProcess(null, cmdLine, null, null, false, PROCESS_CREATION_FLAGS.EXTENDED_STARTUPINFO_PRESENT, null, null, &info, procInfoPtr);
}
string execPath = "notepad.exe\0";
nuint* size = default;
PInvoke.InitializeProcThreadAttributeList(default, 1, 0, size);
STARTUPINFOEXW info = new STARTUPINFOEXW();
info.lpAttributeList = (LPPROC_THREAD_ATTRIBUTE_LIST)Windows.Win32.PInvoke.LocalAlloc(0, (nuint)size).Value;
fixed (char* cmdLine = execPath)
{
  PROCESS_INFORMATION* procInfoPtr = default;
  PInvoke.CreateProcess(null, cmdLine, null, null, false, PROCESS_CREATION_FLAGS.EXTENDED_STARTUPINFO_PRESENT, null, null, &info, procInfoPtr);
}
It still complains about the CreateProcess arguments though

I already had another string Really, the main problem is Visual Studio displaying the error messages for the version using refs etc. making the error messages utterly useless

Ok, I managed to get a char* through fixed (char* cmdLine = execPath) { /* code */ }
