The window I created in C++ is not displayed - c++

Question

I tried to create a window in an Empty C++ Project in Visual Studio, but when I run it, it shows me no window. However, it doesn't give me any error too.
#include <Windows.h>
using namespace std;
int CALLBACK WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow )
{
const auto pClassName = "TextClass";
WNDCLASSEX wc = {0};
wc.cbSize = sizeof(wc);
wc.style = CS_OWNDC;
wc.lpfnWndProc = DefWindowProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = nullptr;
wc.hCursor = nullptr;
wc.hbrBackground = nullptr;
wc.lpszMenuName = pClassName;
wc.hIconSm = nullptr;
RegisterClassEx(&wc);
HWND hWnd = CreateWindowEx(
0,
pClassName,
"A sad Window",
WS_CAPTION | WS_MINIMIZEBOX | WS_SYSMENU,
200, 200, 640, 480,
nullptr, nullptr, hInstance, nullptr);
ShowWindow(hWnd, SW_SHOW);
while (true);
return 0;
}

You have a typo: you are setting
wc.lpszMenuName = pClassName;
instead of wc.lpszClassName.
I believe just fixing that will get the window on the screen but the executable will then hang with it on the screen because nothing is fielding messages.
A minimal message loop instead of
while (true) ...
would be
MSG msg;
while( GetMessage( &msg, NULL, 0, 0 ) > 0 )
DispatchMessage( &msg );
