Is there a 64-bit build of IIS express 7.5?

Question

The documentation at http://learn.iis.net/page.aspx/1010/iis-75-express-readme/ says that:

Both 32-bit and 64-bit systems are supported, however only a 32-bit build of IIS 7.5 Express exists.

Why is this limitation there? are there any plans to get a 64-bit build?

I'm getting a lot of OOME using the 32-bit express on my test machine ... how were are supposed to simulate running on the real IIS, if the test server is so limited ...

Answer 1

IIS Express 8.0 has 64-bit support. At the time of writing it's an RC.
