I am trying something in VS2010 where I attach a entity to my context but then I try to simply do a ChangeObjectState and it doesn't exist anymore it seems.  How do I update a object?  I used to just do the following:

context.attach(address);
context.ObjectStateManager.ChangeObjectState(address, EntityState.Modified);
context.SaveChanges();

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
