Microsoft.Web.Atlas.dll and IIS7 Integrated mode

I'm moving a website from IIS6 to IIS7 and I can’t get Microsoft.Web.Atlas.dll to work when IIS7 is running in integrated mode. It works fine in classic mode. I just get an unknown error d开发者_如何学运维ialog and I can see it's a 500 error on the server. When doing a trace the only information I get is that it's the error is from ManagedPipelineHandler. Ideas?

As you're probably aware, Microsoft.Web.Atlas.dll was the CTP of the ASP.NET AJAX components (from circa 2005/6). Unfortunately I and probably many others have long disposed of this CTP so I can only speculate as to what may be wrong and some possible fixes:

1. Try adding any Atlas specific handlers and modules to the <system.webServer> section of your web.config file.

2. If the new server is running 64-bit windows try switching the application pool the site resides in to 32-bit mode.

3. Configure the site's application pool to run ASP.NET 2.0 and not ASP.NET 4.0.

4. Because it's so old and it was a CTP, Atlas may not even be compatible with Integrated Pipeline mode.

5. Consider updating the code to use Microsoft AJAX 2.0 RTM.
