title: Is Visual Studio 2010 WebDev WebServer (Cassini) 64-bit compatible?
body: <p>I'm now developing on Visual Studio 2008 on a 64-bit OS (Windows Server 2008 64-bit).</p>
  
  <p>While the apps I write are 64-bit capable, as is IIS7, the built-in ASP.NET Development Server (aka Cassini aka WebDev.Webserver.exe) runs as 32-bit.</p>
  
  <p>This brings up a plethora of issues, such as:</p>
  
  <ul>
  <li>32-bit and 64-bit applications have separate HKLM\Software registry homes</li>
  <li>There are 32-bit and 64-bit versions of the SQL Server Client Network Utility</li>
  <li>Other fun surprises I haven't discovered but I'm sure will spring up</li>
  </ul>
  
  <p>While I am finding workarounds for most of this, I have to ask...</p>
  
  <p>Does anyone who has played with the Visual Studio 2010 preview bits on 64-bit architecture know if the development web servers can handle 64-bit, and if so, are there options for which mode to run it in?  (Like a checkbox in the project properties, for instance)</p>
