Simple Injector - Lifestyle Mismatch

Question

I am using unit of work pattern for my transitions. I created an DbContext which is handling connection, commit, rollback works.

In my data access and business layer classes, I inject IDbContext by constructors.

public TestDAL(IDbContext dbContext) : base(dbContext) {}

public TestService(IDbContext dbContext, ITestDAL testDAL) {}

I moved simple injector from autofac. I'm getting an exception about lifestyle mismatch.

-[Lifestyle Mismatch] TestService (Async Scoped) depends on IDbContext implemented by DbContext (Transient).

-[Lifestyle Mismatch] TestDAL (Async Scoped) depends on IDbContext implemented by DbContext (Transient).

I register my DAL and Service classes as scoped and DbContext as transient.

var ServiceRegistrations =
                from type in Assembly.GetExecutingAssembly().GetTypes()
                where type.Name.EndsWith("Service") && type.IsClass
                from service in type.GetInterfaces()
                select new { service, type };

foreach (var reg in ServiceRegistrations)
{
    container.Register(reg.service, reg.type, Lifestyle.Scoped);
}

container.Register<IDbContext, DbContext>(Lifestyle.Transient);

I read some about DbContext should be transient, it is not thread safe. Also I think DAL and Service classes not necessary to create transient. How can I fix this situation? Btw, that was not problem at autofac.
