A simple solution that works is:

Add the following line to the webconfig

...

<trust level="Full" legacyCasModel="true" />

...

</system.web>

This MSDN link talks about creating XBAPs in .NET 4 and how to create a Full-Trust XBAP:

I added  [assembly: System.Security.SecurityRules(System.Security.SecurityRuleSet.Level1)] to the DomainModel Assembly.cs file as well as the xbap app Assembly.cs file. This causes a new issue:

The type initializer for 'LOC.AMP.Data.DomainModel.EntityManager' threw an exception. which is thrown at the Login method of my LoginClientCore class.
 
INNER Exception:
Request failed
Stack:
   at LOC.AMP.Data.DomainModel.EntityManager..cctor()
Method:
'((System.Security.SecurityException)(((System.Exception)($exception)).InnerException)).Method' threw an exception of type 'System.Security.SecurityException'
PermissionState:
'((System.Security.SecurityException)(((System.Exception)($exception)).InnerException)).PermissionState' threw an exception of type 'System.Security.SecurityException'
PermissionType:
{Name = "PermissionSet" FullName = "System.Security.PermissionSet"}
PermitOnlyInstance:
'((System.Security.SecurityException)(((System.Exception)($exception)).InnerException)).PermitOnlySetInstance' threw an exception of type 'System.Security.SecurityException'
RefusedSet:
'((System.Security.SecurityException)(((System.Exception)($exception)).InnerException)).RefusedSet' threw an exception of type 'System.Security.SecurityException'
Zone:
System.Security.SecurityZone.MyComputer
'((System.Security.SecurityException)(((System.Exception)($exception)).InnerException)).Url' threw an exception of type 'System.Security.SecurityException'

I did some poking around and .NET 4 has a lot of changes to partially trusted assemblies and code access security. 

Try searching for:
"Inheritance security rules violated by type" .net 4
and
"Derived types must either match the security accessibility of the base type or be less accessible" .net 4
 
Many of the discussions point to adding this attribute to your assembly:
[assembly: System.Security.SecurityRules(System.Security.SecurityRuleSet.Level1)]
 
There's some other suggestions there that might be worth trying as well.  Let us know what you find.

Nope:

[KnownType(typeof(BaseEntity))]

public partial class BaseEntity : IbEm.Entity, IDXDataErrorInfo

Do you have an injected base class that is not public?  That's the only thing I can think of that would cause that message.

I am trying to make my project xbap accessible as well as windows accessible. When I do I get the following error:
 
Inheritance security rules violated by type: 'LOC.AMP.Data.DomainModel.BaseEntity'. Derived types must either match the security accessibility of the base type or be less accessible.
 
I am assuming web does not have the same permission. Suggestions on how to work with this?
