D2D with ID3D11On12Device

Question

From a Directx12 project template created with Visual Studio 2019:

I added to "pch.h" as follows:
#include <d3d11on12.h>
#include <d2d1_3.h>
#include <dwrite.h>

Based of reading this article:
https://learn.microsoft.com/en-us/windows/win32/direct3d12/d2d-using-d3d11on12#:~:text=The%20D3D1211on12%20sample%20demonstrates%20how%20to%20render%20D2D,D2D%20factory%20Create%20a%20render%20target%20for%20D2D

I added to the top of DeviceResources.cpp these items:
static UINT d3d11DeviceFlags;
static ComPtr <ID3D11DeviceContext> m_d3d11DeviceContext;
static ComPtr <ID3D11On12Device> m_d3d11On12Device;
static ComPtr<ID3D11Device> d3d11Device;
static ComPtr<ID2D1Factory3> m_d2dFactory;
static ComPtr<IDXGIDevice> dxgiDevice;
static ComPtr<ID2D1Device> m_d2dDevice;
static ComPtr<ID2D1DeviceContext> m_d2dDeviceContext;
static ComPtr<IDWriteFactory> m_dWriteFactory;

I appended to the end of "void DX::DeviceResources::CreateDeviceResources() { ... " in DeviceResources.cpp:

	ThrowIfFailed(D3D11On12CreateDevice(  
		m_d3dDevice.Get(),  
		d3d11DeviceFlags,  
		nullptr,  
		0,  
		reinterpret_cast<IUnknown**>(m_commandQueue.GetAddressOf()),  
		1,  
		0,  
		&d3d11Device,  
		&m_d3d11DeviceContext,  
		nullptr  
	));  
  
  
	// Query the 11On12 device from the 11 device.  
	ThrowIfFailed(d3d11Device.As(&m_d3d11On12Device));  
  
  
	// Create D2D/DWrite components.  
	{  
  
  
		D2D1_DEVICE_CONTEXT_OPTIONS deviceOptions = D2D1_DEVICE_CONTEXT_OPTIONS_NONE;  
		D2D1_FACTORY_OPTIONS d2dFactoryOptions;  
		d2dFactoryOptions.debugLevel = D2D1_DEBUG_LEVEL_INFORMATION;  
		ThrowIfFailed(D2D1CreateFactory(D2D1_FACTORY_TYPE_SINGLE_THREADED, __uuidof(ID2D1Factory3), &d2dFactoryOptions, &m_d2dFactory));  
		ThrowIfFailed(m_d3d11On12Device.As(&dxgiDevice));  

		ThrowIfFailed(m_d2dFactory->CreateDevice(dxgiDevice.Get(), &m_d2dDevice)); <--Exception is Thrown  

		ThrowIfFailed(m_d2dDevice->CreateDeviceContext(deviceOptions, &m_d2dDeviceContext));  
		ThrowIfFailed(DWriteCreateFactory(DWRITE_FACTORY_TYPE_SHARED, __uuidof(IDWriteFactory), &m_dWriteFactory));  
	}  

Does anyone know why an exception is being thrown at the line:
ThrowIfFailed(m_d2dFactory->CreateDevice(dxgiDevice.Get(), &m_d2dDevice));

Things don't seem to run past that point and an exception is thrown? Is it possible to know how to fix the exception being thrown. I would like to use D2D with DirectX12 to draw simple 2D graphics to the screen.

Thank you....

I believe that it is described here:
https://github.com/microsoft/DirectX-Graphics-Samples/tree/master/Samples/UWP/D3D1211On12/src
how to set that up in UWP and that the device that is created would have to be created in a compatible form with appropriate flags for use with a Direct2D context.
