Visual Basic — mono

Visual Basic 8 fully supported. vb9 (in visual studio 2008) is not.
mono includes visual basic compiler (vbnc)
works with MonoDevelop 0.13 and later

Although binaries compiled with Microsoft's VB.NET compiler would run unmodified on Linux, it was not possible to use VB code in ASP.NET applications (as those get compiled on the first page hit) or if developers wanted to debug and tune up a few things on their target Linux/OSX machine. [1]
