title: Entity Framework doesn't update data value changes made from database
body: <p>I didn't know quite how to word this. I have an ASP.NET MVC 3 web application with a pretty standard EF 4.1 code first with existing database (non-auto-generated) repository pattern. There's a context which is under a dataservice the web app talks to.</p>
  
  <p>The problem I have is this: say I have a database table with an integer column. The value is 10. If I go into the database itself and enter 25 into the table, no matter how many times I hit refresh on the browser, close the browser and reopen it, clear the browser history, etc, it still persists the value of 10. I have to republish the site.</p>
  
  <p>Why does it do this? Am I blaming the right thing here? Is this an EF problem? an ASP.NET problem? Server problem? ... I don't know where to look into this.</p>
