Question

How does the designer work in Visual Studio?
Does it build the view similar to some browser or does it have its’ own rules?

The reason I’m asking is because the code below will show in design view.

<!--[if lt IE 7]>
<div>Some text to warn users with IE6 or earlier versions.</div>
<![endif]-->

…or is it as easy as: All code will show up in design view.

Your conditional comments worked for me with VS 2010. What version of VS do have installed?

My guess is that your using an older version of VS and the internal browser is a plain old IE6.0 embedded WebBrowser control. If so its not likely to have its own rules.

It looks like the Visual Studio 2010 SP1 internal browser is IE7.0 (Man that explains why it is so useless). I get the following details from the internal browser.

Browser Name: Microsoft Internet Explorer

Browser Version: 4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; InfoPath.3; .NET4.0C; .NET4.0E; MS-RTC LM 8)

To test this out for yourself, add the following code to an ASPX page, build, and then view the page with the internal browser

<div id="example"></div>
<script type="text/javascript">
    txt += "<p>Browser Name: " + navigator.appName + "</p>";
    txt += "<p>Browser Version: " + navigator.appVersion + "</p>";

    document.getElementById("example").innerHTML = txt;
</script>
