[C#] Why is DWORD mapped to uint?

[workgroupengineering]

Hi,
I'm taking the first steps in using CsWin32. I tried generating CheckMenuItem.

/// <inheritdoc cref="CheckMenuItem(winmdroot.UI.WindowsAndMessaging.HMENU, uint, uint)"/>
[SupportedOSPlatform("windows5.0")]
internal static unsafe uint CheckMenuItem(SafeHandle hMenu, uint uIDCheckItem, uint uCheck)
{
	bool hMenuAddRef = false;
	try
	{
		winmdroot.UI.WindowsAndMessaging.HMENU hMenuLocal;
		if (hMenu is object)
		{
			hMenu.DangerousAddRef(ref hMenuAddRef);
			hMenuLocal = (winmdroot.UI.WindowsAndMessaging.HMENU)hMenu.DangerousGetHandle();
		}
		else
			throw new ArgumentNullException(nameof(hMenu));
		uint __result = PInvoke.CheckMenuItem(hMenuLocal, uIDCheckItem, uCheck);
		return __result;
	}
	finally
	{
		if (hMenuAddRef)
			hMenu.DangerousRelease();
	}
}

Why does the generated code use uint as the return type instead of int?

The API is defined as returning a DWORD which is, in fact, a uint, so it looks like the projection and the metadata are behaving as expected here.
