Nodes can now be implemented by arbitary C# methods. Graph structure is specified through expression trees implemented using Bg* types, which are not substituted with values until execution time. Doing so allows determination of node and option dependencies for a particular target, allowing us to generate dynamic UI for presenting relevant settings to the user.
Includes partial implementation of Installed Build script as an example implementation.
