When I refresh the entity framework with big table, I get the System.OutOfMemoryException.
Is there any better way to refresh the EF with big tables? I'm using .Net 3.5
I ran into this problem using EF4 and a self-referential table (implementing an adjacency list hierarchy). NOTE: not a many-to-many reference, just a one-to-many on a single table. Attempts to resolve an intermittent InvalidOperationException ("...The ObjectContext might be in an inconsistent state...") using Context.Refresh fail due to an apparent bug in EF4. I saw, from following Shimmy's connect.microsoft.com link, on the aforementioned post, that the bug is still outstanding. Can anyone recommend a workaround? What do you do if your database and Entity Framework get out of sync?
When I get the InvalidOperationException and the message says "The changes to the database were committed successfully...", it is not true. They weren't. I tried to change an object's ParentId from 1 to null (ParentId of type int?). My object's ParentId attribute is correctly changed to the expected value (null). I call Context.SaveChanges(). Then, the exception is thrown. I check the DB, and the value has not been updated. In this case, ParentId is still 1 in the database...................
Is there a way to export a EF 4.0 Data Model to EF 3.5?
I looked around and found that we are not able to access EF 4.0 from a ASP.Net 3.5 project here: [URL]
Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.
Does anyone know why this happens?

It was running fine and then all of a sudden this message poped up.
I have an XElement object that contains about 120MB of data. The XML consists of approx 6000 elements of about 20kb each.
I am trying to call XElement.ToString() as I need to return the OuterXml in a webservice.
I am getting a System.OutOfMemoryException.
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown:

I have the same data in an XmlDocument and can call XmlDocument.OuterXml without a problem. I can also call XElement.Save() to save the XML to a file without a problem.

I have a website that I have run for years running a custom built CMS. It has had no problems ever. I decided to create a demo (temporary url) of the CMS using the exact same website. Only people I give access to would be able to login and change it, so it basically is not in use for the most part.
I tried this demo site the past few days, and I noticed that I kept getting System.OutOfMemoryException errors. I would wait for an hour or so, then it would work. Next day, same thing.
What could explain this? 2 exact same websites....one that is used all the time (no memory issues), and one that is hardly ever used (memory issues). Doesn't really make sense to me.

i have a file upload control in my page and have set the max file size in web.config to 1 GB (this is an intranet app).
However, when I try to upload a 280 MB file, it throws System.OutOfMemoryException. The server has 4 GB of RAM and plenty of disk space.
I have an ashx handler with the following code. The idea is to hide the path of the file and prompt a download

View 1 RepliesI have an EDM, it includes the entities extension and history. My goal is to use history to keep track of all the changes made to extension entity. For example, if extension with ID 223 has its property 'Name_Display' changed - I want the history entity to record this.
I'm using ASP.NET with VB.NET. Where in my code do I put the hook to say, "update the history entity" and what should that hook look like?

I am mapping a stored procedure to an entity by right clicking on the entity (in the .edmx) and selecting "Stored Procedure Mapping." This brings you to a Mapping Details - "Name of Entity" Window that allows you to select the insert, update, and delete stored procedures associated with the Entity. It also maps the stored procedure parameter to the Entity "Property" (Column).
I'm gettin an error "error 2042: Parameter Mapping specified is not valid." The cause of the error is fairly obvious, in the Insert stored procedure that has been selected, a 'CHAR' parameter is being mapped to an Int32 Entity Property. I altered the stored procedure parameter to match the entity, I deleted the stored procedure, readded, and reslected it as the Insert function. I also cleaned, validated, updated model from database. No matter what I do, the parameter list in the mapping details doesn't reflect the change to the stored procedure. It's stuck on a char --> int32 mapping, even though it has been changed, like it's buried deep in meta data some where.
I am trying to add a new entity and have to refernce associated data to add it. I cannot load the Referencetables. Giving "The EntityReference could not be loaded because it is not attached to an ObjectContext." How do i complete this task in Entity Framework 3.5
