My context looks like: public class ApplicationDbContext: IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("DefaultConnection") { this.Configuration.LazyLoadingEnabled = true; } //DbSet properties } so, lazy loading is enabled. I have following class: public class Home { private ICollection<Slide> _slides; [Key] [Required] public string Name { get; set; } [ForeignKey("Header")] public int? HeaderID { get; set; } //Navigation properties public ICollection<Slide> Slides { get { return _slides ?? (_slides = new List<Slide>()); } set { _slides = value; } } public Content

We decided to use a micro-orm against an Azure Database. As our business only needs "inserts" and "selects", we decided to suppress all code-managed SqlTransaction (no concurrency issues on data). Then, we noticed that our instance of Azure Database responded very slowly. The " rpc completed " event occured in delays that are hundreds times the time needed to run a simple sql statement. Next, we benchmarked our code with EF6 and we saw that the server responded very quickly. As EF6 implements a built-in transaction, we decided to restore the SqlTransaction (ReadCommited) on the micro-orm and

What I want to achieve is the simple sql query: UPDATE TABLE SET COLUMN = COLUMN + 1 Is there a way to make it happen without loading all records (thousands) to memory first and loop through each record to increment the column and then save it back? EDIT I tried raw sql and it worked. I have to decide the sql provider from the connection string and the database schema name from the connection context. After that, I will use the corresponding sql query to update the table. For SQL, it looks like UPDATE schemaname.TABLE SET COLUMN = COLUMN + 1 . for POSTGRESQL, I have to double quote schema name

I have created migration and created the database and the tables . For example the tables are A B C D E . Now again I have changed some part of code and ran update-database command . Everything went smooth and nice and the tables showed the columns . Now accidentally I manually deleted one two tables D and E . Now when I try to run the migration with update-database . It runs properly but doesn't create the tables which I deleted manually . I tried to delete the existing migration and re-run update-database . It gives the error that apart from the two tables . There already an object existing

Does Visual Studio 2015 include .edmx support? I have a project that includes an .edmx data model and double-clicking it in VS2015 just opens the XML editor. There's no DbContext generator option in the file->new dialog. During setup of VS2015, go to the advanced options and select Web or Database Development tools. Now the Installers install the EF tools (Designer + templates). If you have VS already installed, to the Programs & features in control panel and modify the currently installed VS2015. You have to select the Microsoft SQL Server Data Tools in the VS2015 setup to get this editor

I have an Entity Framework 6 CF project that has a few migrations already in place. The model is now stable and there is no need to keep the migration history that already exists. Is there a way to reset the model and merge all migration commands into the initial migration? As an example, the first migration adds a column while the second migration adds a unique, non-clustered index. I now want to see all these changes directly in OnModelCreating rather than in separate migrations. Migrations have both an Up and Down . You can always Re-Scaffold your application by tearing the migrations down

I have my database with table names starting with "tbl" prefix and column names like "ua_id" which are understandable in context of project but problematic if used in a model i.e names should be readable or meaningful(not like indicative names defined in database). So I want to map them in my onmodelcreating method but I have no idea about it. I studied it in following blog: http://weblogs.asp.net/scottgu/entity-framework-4-code-first-custom-database-schema-mapping but this is for EF 4.1 and method doesn't work for EF 6.(mapsingletype method) I want to map my tables by columns to my model as I

I'm trying to migrate old project from Linq2Sql to EF6 and I got following issue. This project is multilingual (i.e. all texts have more than 1 translation) and I have following db structure: What is the best way to get all ExampleEntity1 objects with all LocalizedContent records filtered by current language id? I can load all ExampleEntity1 objects with all LocalizedContent records using following code: dc.ExampleEntity1.Include(ee => ee.TextEntry.LocalizedContents); In Linq2Sql I can filter LocalizedContent records using loadOptions.AssociateWith but I can't find any solution for EF6. I saw
