Ok, this is what I got. How do I find out which are a problem in a partially
trusted system?

Hello Dave,.
From your description, you have changed the trust level of your ASP.NET web
application(to partial trust) and now you'll encounter .net CAS permission
error when try running the application ,correct?
Based on the exception callstack and message you provided, the problem is
caused by the following assembly:
==============
Could not load file or assembly 'WindwardReports,
Version=4.1.35.0, Culture=neutral, PublicKeyToken=34ffe15f4bbb8e53' or one
of
its dependencies.
==============
The minimal requested permissions are violating the host environment's
trust level. I think you can check the permission through the following two
steps:
** Verify your current ASP.NET application's trust level(high or medium
or...) and find that level's policy file(in framework's config folder
----C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG) and verify
whether that assembly contains any code that violate the CAS permissionset
allowed in that policy.
** for assembly, .net 2.0 provide the permcalc.exe tool which can help
verify the minimum permission sandbox in which an application can run.
#Permission Calculator Tool (Permcalc.exe)
http://msdn2.microsoft.com/en-us/library/ms165077(VS.80).aspx
e.g.
Permcalc.exe -sandbox mylib.dll
Hope this helps.
