Project works fine in ASP.NET Core 6.0 but when I tried to migrate it to 7.0, it builds successfully without errors but at runtime I got this error:
Message "GenericArguments[0], 'AbilityFix.Model.Models.Forums', on 'T MaxIntegerT' violates the constraint of type 'T'." string
InnerException {"Method System.Linq.Enumerable.MaxInteger: type argument 'AbilityFix.Model.Models.Forums' violates the constraint of type parameter 'T'."}
System.Exception {System.Security.VerificationException}
Error in startup.cs file

I am working on a web application that uses built-in security classes to create new users
newuser = MembershipUser.Create(relevant parameters)
that is all well and good
it then issues a Profile.GetProfile(newuser.UserName)
which drills down to a
System.Activator.CreateInstance(Type type, Boolean nonPublic)
which throws a
Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentNullException: Value cannot be null.
Parameter name: type
it works fine in dev (visual Studio 2015 Community)
the current site was developed on an older machine, probably Visual Studio 2010
and works just fine
why am I getting these errors - and how do I fix it?
I have taken the following example code from the Unity documentation, and yet a basic controller can't be instantiated with a service implementation as a required constructor dependency.
public static void RegisterTypes(IUnityContainer container)
{
container.RegisterTypes(
AllClasses.FromLoadedAssemblies(),
WithMappings.FromMatchingInterface,
WithName.TypeName,
WithLifetime.ContainerControlled);
}
This gives the error Exception information:
Exception type: ResolutionFailedException Exception message:
Resolution of the dependency failed, type =
"[XXX].Controllers.HomeController", name = "(none)". Exception
occurred while: Calling constructor
Microsoft.Practices.Unity.InterceptionExtension.PolicyInjectionBehavior(Microsoft.Practices.Unity.InterceptionExtension.CurrentInterceptionRequest
interceptionRequest,

Exception is: ArgumentException - Type passed must be an interface

I created a entityFramework migrations where I have a class library for data entities and combined it with the AspNet Identity within the web application. No error so far. I created a IndentityDB that has the defaultConnection and updated the AccountController to point to the connection
(New UserStore(Of ApplicationUser)(New IndentityDB())))
seems to be right with no error on the build except for a enum issue in the classlibrary that I will fix later but I get a error:
'ViewBag' is not declared. It may be inaccessible due to its protection level.
