    <p>I'm using EF4 with Visual Studio 2010 and SQL Server 2008 R2.</p> <p>I am selecting an entity. After that I call a stored procedure which updates that entity en reselects it from the database. When I catch the result of the stored procedure in code, I see that the old (previously selected) properties. </p> <p>Obviously I'm looking at the cached entity value. Is there a way to signal EF that my entity was updated? Or a magic property of some sort?</p> <p>My database table (and entity) look something like this:</p> <pre><code>CREATE TABLE [Message] ( ID int IDENTITY(1, 1) PRIMARY KEY, Content XML, StateID int NOT NULL, ) </code></pre> <p>My SP is something like this:</p> <pre><code>CREATE PROCEDURE sp_Queue_s AS BEGIN DECLARE @queue table ([ID] int NOT NULL) BEGIN TRAN INSERT INTO @queue SELECT [ID] FROM [Message] WHERE StateID = 1 UPDATE [Message] SET StateID = 2 WHERE ID IN (SELECT ID FROM @queue) COMMIT TRAN -- Select the queue SELECT [ID], [Content], [Message] FROM [Message] WHERE [ID] IN (SELECT ID FROM @queue) END </code></pre> <p>My C# code looks something like this:</p> <pre><code>using (var context = new MyEntities()) { int id = 1; var message = context.Messages.Single(m =&gt; m.ID == id); var messages = context.GetQueue(); // Function import of sp_Queue_s, maps on the Message entity var messageUpdated = messages.Single(m =&gt; m.ID == id); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
