I am migrating my app from UWP to WinUI 3 in Desktop with windows app sdk. I used to print using print manager in uwp.

So printing a file in Windows App SDK by printing thought processstartinfo with verb "print" its not working. is this a right way to print or are they any API's specific to Windows App SDK

    This test with a "e:\test.txt" file works for me in a Windows App SDK C++ Desktop app :

    At beginning : 

    #pragma comment (lib, "Shell32")

    Then : 

    ShellExecute(0, L"open", L"rundll32.exe", L"C:\\windows\\system32\\mshtml.dll, PrintHTML \"e:\\test.txt\"", NULL, SW_SHOWNORMAL);

    ("print" or "printto" verbs with the file instead of "open" can also be used, but it depends on registry associations)
