entity-framework-5

I'm using Entity Framework 5 with Code First. I've written a custom IDbConnectionFactory which I want to use for all the connections made by my DbContext class, so early on in the application's lifecycle, before any database work is done, I call Database.DefaultConnectionFactory = new MyConnectionFactory(); However, MyConnectionFactory.CreateConnection is never called, which suggests to me that EF's changed it back - but the debugger shows that it's still a MyConnectionFactory after several queries have run. For some reason, it's just not using it. My DbContext is initialised by passing the

I am using entity framework DB first approach and wants to know how can i manage migrations in DB first approach. We're doing changes in database schema manually. Is there any way by which Entity Framework can apply the changes accordingly to the project.

I would like for it to use SQL Server by default for everything when I start a new ASP.NET MVC 4 Web Application project.

We are experiencing very poor performance using Entity Framework 5.0 with MySql Connector 6.6.6.0 for count based queries. Our data structure looks like: Table: Post =========== ID INT PRIMARY KEY MemberID INT NOT NULL SiteID INT NOT NULL Description VARCHAR(255) NOT NULL Image VARCHAR(255) NOT NULL CreatedDate DATETIME NULL And using entity framework with a linq query like the following: var count = entities.Post.Where(p => p.SiteID == 1 && p.CreatedDate != null).Count(); We get the following generated SQL: SELECT `Extent1`.`ID`, `Extent1`.`MemberID`, `Extent1`.`SiteID`, `Extent1`.

After several hours of trial and error, I reached to this thread which explains how to establish a One-To-Many relationship and a One-To-One relationship with the same two types. However, I cannot get this to work with Cascade Delete: Thrown: "Unable to determine a valid ordering for dependent operations. Dependencies may exist due to foreign key constraints, model requirements, or store-generated values." (System.Data.UpdateException) Exception Message = "Unable to determine a valid ordering for dependent operations. Dependencies may exist due to foreign key constraints, model requirements,
