I gotcha …
That is not possible right now.
I did implement an semi work around at some point, where you can set on a project to not cache it ( so the xaml files are not stored on the client ) so if you run the robot in agent mode, the user would not be able to see the workflow. But in reality that is “security through obscurity” and not really a good way to “protect your IP”. ( but if we need to nit pick, neither is creating a dont net .dll since those can be decompile easily or the xaml found as an resource in the .dll )
Anyway, in openrpa’s code base you can see/find code for how to compile an xaml file into a dll but there is no way to do this using the UI in OpenRPA right now. You could use that code to either compile a type in memory and add to the toolbox from a dll, OR compile to a dll, and distribute the dll. But either way would require you to use Visual Studio ( and depending on how flexible you make your project you could create a generic solution to work across multiple solutions or one per nuget package )
