Entity Framework does not remove deleted table (EF6) - entity-framework

I have a database-first model, if I "Update model from database" the wizard shows the new table and it is added to the model just fine.
If I delete that table and update again, the table shows on the 'Delete' tab of the wizard but after clicking 'finish' the object still shows on the edmx diagram and the table's class file is still in my project - am I missing something here?

Strangely it seems that this is by design, it means that for now you need to know the DB design changes and manage the EF model manually.
I have logged a feature request on the EF site.

Newly Added Table missing in Entity Framework

I am Using VS2013 and EF6.0 with MS SQL Server 2012. For EF6.0 I choosen
"Generate from Database". Then It brought all the table in the Database. Now I have Added new table called "LoginEntry" in same database. It is showing in SQL Server newly added table.
When I am trying update EDMX file using "Update Model from Database" option, It shows the new table. but when i checked on the table and the options and click "Finish". It is not updating the EDMX as well in diagram also. I tried Many times. Can anyone suggest pls?
I added Primary Key to the newly added table. Then it came to picture. Thank you guys for your suggestion

Entity Framework: Added view appears in Model Browser but not Solution Explorer

I have a project which uses Entity Framework. I've added a view from my SQL Server database to the model using the Model Browser in Visual Studio 2012 such that it appears under the following items:
Entity Types under my model.
Entity Container, Entity Sets
.Store, Tables / Views
However, I can't access it from my code.
Back in Solution Explorer, under the Models folder, the view does not appear anywhere under the EDMX file for my model (though it DOES appear in the diagram).
I can not seem to find any practical way to add the view to my data model such that it is usable. Ultimately, I want to reference it via the entities object so I can select data from it.
Every Entity in EF should have unique identifier. Try to select a key column in view and then try to add view. View should be available to you

How can I add tables to a model?

I added new table to my database and I managed to add it to my data model, using "Update model from database" option. But I cant generate class to acces this table in code. "Add code generation item" results into creating classes for all tables i have in my database.
Well, it seems to be a duplicate, but don't delete this topic at once please, for I've been searching for solution quite a long time and found nothing helpful.
You don't need to add code generation item again if you already did it once. Normally it should be enough to save your EDMX file and generation should trigger. If it for any reason doesn't work, right click on .tt file responsible for generating your classes in the Solution Explorer and select Run Custom Tool from the context menu.

Update model from database - refresh one table

Is it possible to refresh only one entity in entity framework designer? Every time I refresh model from database, it refreshes all entities. The problem is that this mechanism doesn't recognize properly primary keys in views, so I have to correct it manually. Am I missing something?
No, you're not missing anything. When you update model using the GUI designer, the entire storage schema is regenerated. At least, that's how it works in Entity Framework 1.
I can't tell you if you can or can't do it, but I have one clue how to figure it out.
http://code.msdn.microsoft.com/EdmGen2
EdmGen2 contains source code and dll probably with functionalities from usual EdmGen.
Unfortunately I didn't have time to investigate this further. Hope this helps.

What's the easiest way to refresh Entity Model after adding/deleting DB fields?

Does anyone know what the esiest way to update the entity model after adding/deleting the fields in the database?
I am adding a few new fields to my database, then choose "Update Model from DB" and nothing happens. The model stays intact. Did anyone encounter the same problem?
Thanks for any feedback!
With EF that shipped for .net 3.5 I tend to follow the following steps:
Delete the connectionstring
Delete the model
Generate a new model
Build solution
This is perhaps not a very solid approach but it saves me time in the long run. In the future it is easier and more stable to do a refresh but I have gone from autogenerating my model to model-first.
I would definitely check out the EDM Generator which allows you to do a full generation of the model from scratch - Click here to go to the MSDN reference. It has saved me a lot of time and hope it will do the same for you.
