WPF Control, How to set transparency?

[rafayahmed317]

I know the work is going on for the WPF and UWP controls, but I was looking on how to set the transparency for the WPF terminal control. Currently, it seems that the theme allows only for a solid background color, so I modified the TerminalSetTheme Method to also do EnableTransparentBackground(true) , however still the terminal control loads using the Background solid color, I looked up the source code for the Terminal app to see how it was doing this, and aside for the EnableTransparentBackground setting (I dont know c++. so I certainly have missed something), I was unable to locate how it did this. That means that I could not find where the transparency setting should be made, does the renderer does this, or will I have to modify something else?
