I installed Ruby In Steel Trial Edition for Visual Studio 2008 and when I try to save an IronRuby Project, it keep warning:

"The operation could not be completed. No such interface supported".

I cannot save the project but only run it.

Just restarting Visual Studio solves the problem sometimes.

    i upgraded from VS17 to VS19 and got this error when opening a VS17 project. Restarting VS resolved it (reloading project did not) – Piotr Jul 16 '21 at 17:06

Most probably: Either your installation is corrupt or, you have hit upon a VS bug. See this blog post and the corresponding bug filed with MS.
