When I want to use Sandboxie with the screen I want

[CJungHwi]

I don't want to install Sandboxie, but I want to register the Sandboxie service and develop the user UI screen separately. Can I use it by customizing it without license issues? If so, please tell me how to do it. I would be very grateful.
(I haven’t done C/C++ development before...)

No problem,but you will find you have to use self-compilied build on test mode.

Thank you.
I have never worked with c/c++ before, so I don't know where to start.
First of all, I don't think I need the entire source code,
but what sources do I need to build self-compiled, and how do I do it?
Also, the UI is planned to be developed using blazor hybrid winform. Are there any problems with integration?

I've never dealt with C/C++ before, so please give me some advice.
