class RenderContext(D3D11RenderContext). Our implementation:

void D3D11RenderContext::Init(void window, void context, Noesis::RenderDevice* device, uint32_t& samples, bool vsync, bool sRGB) override
{
NS_ASSERT(Validate());
NS_LOG_DEBUG("Creating D3D11 render context");

mContext = (ID3D11DeviceContext*)context;
mContext->AddRef();

mContext->GetDevice(&mDevice);

CreateSwapChain(window, samples, sRGB);
CreateQueries();

mVSync = vsync;
mRenderer.Reset(device);

#if defined(NS_PLATFORM_WINDOWS_DESKTOP) || defined(NS_PLATFORM_WINRT)
NS_LOG_DEBUG(" Adapter: %s", [this]()
{
IDXGIDevice* dxgiDevice;
V(mDevice->QueryInterface(__uuidof(IDXGIDevice), (void**)&dxgiDevice));

    IDXGIAdapter* dxgiAdapter;
    V(dxgiDevice->GetAdapter(&dxgiAdapter));

    DXGI_ADAPTER_DESC desc;
    V(dxgiAdapter->GetDesc(&desc));

    static char description[128];
    uint32_t numChars = UTF8::UTF16To8((uint16_t*)desc.Description, description, 128);
    NS_ASSERT(numChars <= 128);

    DX_RELEASE(dxgiAdapter);
    DX_RELEASE(dxgiDevice);

    return description;
}());

#endif
}

D3D11RenderContext::~D3D11RenderContext()
{
. . .
DX_RELEASE(mContext);
DX_RELEASE(mDevice);
. . .
}

It is possible to add the interface ISwapChain for NoesisApp :: Window?
