using namespace System::Diagnostics;
using namespace System::ComponentModel;

int main()
{
    Process^ myProcess = gcnew Process;

    try
    {

        // You can start any process, HelloWorld is a do-nothing example.
        myProcess->StartInfo->FileName = "C:\\HelloWorld.exe";
        myProcess->StartInfo->CreateNoWindow = true;
        myProcess->Start();
        // This code assumes the process you are starting will terminate itself. 
        // Given that is is started without a window so you cannot terminate it 
        // on the desktop, it must terminate itself or you can do it programmatically
        // from this application using the Kill method.
    }
    catch ( Exception^ e ) 
    {
        Console::WriteLine( e->Message );

Remarks

If the UseShellExecute property is true or the UserName and Password properties are not null, the CreateNoWindow property value is ignored and a new window is created.

.NET Core does not support creating windows directly on Unix-like platforms, including macOS and Linux. This property is ignored on such platforms.
