Embedding UnityPlayer into a Forms application

Hi,

I can embed the UnityPlayer when I Start the player as a sepperate process using the CmdLine argument -parentHWND and the handle of my splitcontainer in my Windows Forms application.
But then you have a sepperate process.
I tried the other method by importing the Dll described here: https://docs.unity3d.com/Manual/UnityasaLibrary-Windows.html
and here: https://forum.unity.com/threads/uni...ly-from-your-own-standalone-launcher.1026745/
But then the game starts and the form is not showing anymore.
Is it possible to embed into the same process and have the player show up on the form ?
Any examples of that around ?
Thanks
