[Mono-list] Language Clarification

[George Birbilis]

why are you compiling on the fly the embedded VB.net code (or the 
code-behind class source if you support codebehind already in mono's 
ASP.net)?

.NET has a on-the-fly compilation feature for ASP.net, but the default is to 
use precompiled .DLLs (to IL) and upon first use of those DLLs they're 
converted to native code and cached
