When you run a .NET Framework 2.0-based application, an access violation occurs. This problem occurs when all of the following conditions are true:
The application calls the IList<T>, IEnumerable<T>, or ICollection<T> interface in a virtual function.
The T parameter is a type that is defined in an assembly that is not loaded as domain neutral.
The call is made on an instance of an array of reference types in a Lightweight Code Gen (LCG) dynamic method.
The LCG dynamic method is defined to have an owner which is loaded as domain neutral.
This problem occurs because the virtual call stubs are created in the location of the loader allocator of the parent type but not in the location of the allocator. Therefore, LCG dynamic methods consider these two locations to be different.
