In a number of our .aspx files, we use conditional script blocks like:

<% #if DEBUG %>
  <link href="debug1.css" type="text/css" rel="stylesheet" />
  <link href="debug2.css" type="text/css" rel="stylesheet" />
<% #else %>
  <link href="release.css" type="text/css" rel="stylesheet" />
<# endif %>

This works under .Net.

This fails under Mono with error messages of the form:

cs1525: unexpected symbol 'if'

Interestingly, I bumped into another unexpected behavior when I tried to work
around it.  I commented the preceeding code as follows:

<!-- <% #if DEBUG %> -->
  <link href="debug1.css" type="text/css" rel="stylesheet" />
  <link href="debug2.css" type="text/css" rel="stylesheet" />
<!--
<% #else %>
  <link href="release.css" type="text/css" rel="stylesheet" />
<# endif %>
-->

I expected that the preprocessor would strip out the sections commented using
<!-- -->.

Instead, under Mono, I continued to receive the CS1525 error.

I was able to comment it out as follows:

<!-- <% // #if DEBUG %> -->
  <link href="debug1.css" type="text/css" rel="stylesheet" />
  <link href="debug2.css" type="text/css" rel="stylesheet" />
<!--
<% // #else %>
  <link href="release.css" type="text/css" rel="stylesheet" />
<# // endif %>
-->

This also commented out the release portion of the .aspx file:

<% // #if DEBUG %>
  <link href="debug1.css" type="text/css" rel="stylesheet" />
  <link href="debug2.css" type="text/css" rel="stylesheet" />
<% // #else %>
<!--
  <link href="release.css" type="text/css" rel="stylesheet" />
-->
<# // endif %>

I assume the last effectively created three empty script blocks and just
commented out the release link.
