[Mono-list] MS ASP .NET Bug

[David Waite]

This is not a bug; the </script> just takes precidence over code
structure; the contents of the script block is interpreted by a
separate engine. Without knowing the grammar of the language you are
using for the script block, the parser has no way of knowing if

 sql += @"

is a valid statement or not.

As someone said, you should divide up the script close tag in your
code. Something like a CDATA block will not work, at least not with
the MS implementation (which appears to be regexp-based rather than
having a real grammar). Another option would be to separate your code
from the page.
