Web Site works fine under IIS, but get SerializationException undervs2005 rc1 web server

[Adam P]

Hi,

When I run my website under IIS, it works fine. When I attempt to run it
as a "file system" website under vs2005 RC1 I get the following error:

Error Message: Type is not resolved for member
'Adeptive.Common.Security.AdeptivePrincipal,Adeptive.Common.Data,
Version=1.0.2095.16903, Culture=neutral, PublicKeyToken=null'.
Page Error Occurred: /ClientWeb/RecordTime.aspx
ExceptionType: System.Runtime.Serialization.SerializationException
Stack Trace:

....

Adeptive.Common.Data is an assembly that is in the bin directory.

Any ideas?

Thanks,

Adam
