Hey, I've been on an odyssey to port this (for a very liberal definition of "port") to .NET for many months!

The underlying library [Incremental][0] [is ported][1] though currently unused; the "ported" framework itself doesn't yet include any Bonsai magic, but the terminal-side stuff is [Zoomies][2], in which [this is broadly what it looks like][3] to write a VDOM (scroll down to line 100 to see how to process user interaction, and line 150 to see how that VDOM renders). All very incomplete and with a big long list of features to add, and the current design is not flexible enough yet to accommodate the "table" primitive, but we're slowly getting there.
