<p>Can you program/configure Visual Studio to produce custom intellisense for your own server controls.</p>

<p>eg can you get it to do this:</p>

<p><a href="http://www.yart.com.au/test/vs.gif" rel="nofollow noreferrer">alt text http://www.yart.com.au/test/vs.gif</a></p>

<p>for a tag of your own like:</p>

<pre><code>&lt;MyCompany:MyTag ...
</code></pre>

Bluevision have a nice plugin for Visual Studio to do this for you. Last time I looked, it was free. (yep, it's still free!)
IntellisenseAttribute class allows you to specify members for which intellisense symbols will be generated.
Ability to generate default intellisense symbols for assemblies when you don't have access to the source code.
NEW Snaps right into the IDE so that intellisense generation can be automated during the build process.
Supports two visual views: Full Mode and Skin Mode.
Full source code.
FREE!
