<p>Starting from ASP.NET MVC Preview 3, HTML.Button ( and other related HTML controls) are no  longer supported.</p>

<p>The question is, what is the equivalent for them? I've an app that was built using Preview 2, now I have to make it compatible with the latest CTP releases.</p>

Just write
```
<input type="button" ... />
```
into your html.  There's nothing special at all with the html controls.
