Is there any option that allows to ignore sys tables when updating model from database?
In my case I always have sysdiagram entity and related objectset.
thanks in advance.
Just deselect the tables you don't want to add/update in the dialog:

I have one table in the database with the name "Users", a year ago one of the developers added a model using database-first approach, and I don't know which entity framework version they used.
Now i want to change some of the fields datatypes in SQL.
The problem is that I am not able to update model using the refresh window and also tried to delete model and add it again, but after that there was a name that has been changed in Users to User.
The current entity framework version is 6.1.3
Just go to your DataBase.edmx and right click "Update Model from Database..." and then refresh the tables
For the table name check link please -> What is the meaning of the "Pluralize or singularize generated object names" setting?
And Ricardo has already written the update.
My EF schema has a mixture of tables and views from my database. My view entities are all read-only, I want to be able to update/insert into these entities. I've tried the following post without any luck:

Anyone have another ideas/pointers - this must be doable.
cheers

Generally the post is correct. Using views in EF is hard. Another trick is first using tables to define your model and then replace tables in database with views with same names as tables.
Have you tried Instead of Triggers?

For integration testing I need to wipe all data information in a database.
I'm using Entity Framework 4
What's the most efficient way?
Would be nice if I don't need to specify table or class names every time I add a new class to the model.
Thanks!
Most efficient way to delete database data is to drop all tables and recreate all tables.
This may not be the fastest, but it is the simplest. It even clears your connection pool:
using (var context = new DataContext())
{
context.Database.Delete();
}
I have a single hosted SQL Server DB and I don't have permissions to drop it. How do I make EF create tables from my domain classes? RecreateDatabaseIfModelChanges and AlwaysRecreateDatabase try to drop DB, CreateDatabaseOnlyIfNotExists doesn't create the tables.
Thx
CreateDatabaseOnlyIfNotExists is the default strategy. It means you don't need to even set it through the Database.SetInitializer. EF Code First will check the database and if couldn't find one with the same name as your context's fully qualified name, it will create one for you.
I have a customer with many Addresses .Deleting the customer should delete all the customerAddresses too.
Provided I have sql server table "Customer" set up to have cascade delete
Is there anything special I need to do to make it work?
Any suggestions
No. It will just works. Cascading delete in a database is picked up by EDM Wizard and you will be having the same rule on your model's associations and it is recommended to have cascade in both the model and the database, or in neither to avoid incorrect expectations and unpredictable results.
