Environment
---------------
Visual Studio 2005
..NET 2.0
Windows XP SP2
Scenario
----------
TCLibrary (Class Library)
• Contains MyIdentity and MyPrincipal classes that implement the IIdentity
and IPrincipal interfaces respectively.
TCWebFile (File-system web site)
• The TCLibrary.dll assembly is referenced using a local reference (.refresh
file in the bin folder.)
• The site is using forms authentication.
• The Application_AuthenticateRequest method in the Global.ascx sets the
current HttpContext.User property equal to a new instance of the MyPrincipal
class.
Problem
----------
The following SerializationException is thrown while processing the initial
request.
Server Error in '/TCWebFile' Application

Analysis
----------
• The executing AppDomain where the exception is thrown is unable to resolve
the TCLibrary.MyPrincipal type.
• The TCLibrary is loaded in the AppDomain where the
Application_AuthenticateRequest is invoked.
• Using a GAC reference to the TCLibrary assembly solves the problem.
• The problem does not occur when the application is hosted by a local IIS
web site.
