Entity Framework + Life Time + StructureMap + Unit of Work + Windows Forms?

I have a Windows service (or Windows Forms) , and after the timer expires, my service performs some tasks.

I do not want to use only one Entity Framework context while my application is running.

I saw a factory session in NHibernate . Is there something similar for EF ?

This is how I use EF + StructureMap in my ASP.NET or MVC applications :

Application start:

ObjectFactory.Configure(Function(config) config.For(Of IUnitOfWork).HybridHttpOrThreadLocalScoped.Use(Of UnitOfWork)())

End Request:

ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects()

My UnitOfWork is running on a web request and located after the request is complete.

    Public Sub New(ByVal databaseFactory As DataAccess.IDatabaseFactory)
        _databaseFactory = databaseFactory
    End Sub

    Public Function GetById(ByVal id As Integer) As Product
        Return (From item In _databaseFactory.GetDataContext.Products Where item.ProductId = id).FirstOrDefault
    End Function

End Class

Public Class ProductService

    Private ReadOnly _Repository As ProductRepository

    Public Sub New(ByVal repository As ProductRepository)
        _Repository = repository
    End Sub

    Public Function GetById(ByVal id As Integer) As Product
        Return _Repository.GetById(id)
    End Function

End Class
