Can't get RhinoMocks to emit a mock that follows the generic type restriction rules

Question

So, using NUnit and RhinoMocks: ``` //Defines basic behavior of all persistable domain objects public interface IDomainObject {...} //defines domain objects specific to the Security DB public interface ISecurityDomainObject : IDomainObject {...} //Defines a basic transactional data Repository; there are multiple implementors //which each close TRest to the interface that defines their DB's domain classes public interface IRepository : IDisposable where TRest:IDomainObject { IUnitOfWork BeginUnitOfWork(); void CommitUnitOfWork(IUnitOfWork unitOfWork); void RollBackUnitOfWork(IUnitOfWork unitOfWork); void Save(T domainObject, IUnitOfWork unitOfWork) where T : class, TRest; IQueryable QueryFor(IUnitOfWork unitOfWork) where T :class, TRest; } public interface ISecurityRepository:IRepository {} public class SecurityRepository:ISecurityRepository ... //This line breaks when run in an NUnit test var securityRepository = MockRepository.GenerateMock

Accepted Answer

It looks like this is a known issue caused by `Castle.DynamicProxy` that is fixed in the latest trunk of that project, but still broken in the latest Rhino Mocks release:

If you're feeling adventurous you can build your own Rhino Mocks with the latest DynamicProxy and it should be fixed.
