How do I do that? Here is the code that is working but gives the 3 warnings for the RegsiterItemCollection

There have been many question on managing EntityContext lifetime, e.g. Instantiating a context in LINQ to Entities I've come to the conclusion that the entity context should be considered a unit-of-work and therefore not reused. Great. But while doing some research for speeding up my database access, I ran into this blog post... Improving Entity Framework Performance The post argues that EFs poor performance compared to other frameworks is often due to the EntityConnection object being created each time a new EntityContext object is needed. To test this I manually created a static
