Add item to many to many entity in Entity Framework
So I have these 2 entities
So I have these 2 entities
I am developing a database using a code-first approach with entity framework.
I want to write some C# code to initialize my database with some seed data. Clearly, this is going to require the ability to be able to set the values of various Identity columns when inserting. I’m using a code-first approach. By default, DbContext
handles the database connection and so you can’t SET IDENTITY_INSERT [dbo].[MyTable] ON
. So, what I’ve done so far is use the DbContext
constructor that lets me specify a DB connection to be used. Then, I set IDENTITY_INSERT
to ON
in that DB connection, and then try to insert my records using entity framework. Here’s an example of what I’ve got so far:
MVC4 + Entity Framework 4.4 + MySql + POCO/Code First
I’m using Code First concept in Entity Framework and I’m constantly getting the following exception while starting application:
I have models based on EF Code First and I want to use them with the default MembershipProvider, but I don’t know how to write the model correctly, so it won’t erase all my data on recreating the tables when there were changes made to the model.
I prefer working with Fluent API configuration to DataAnnotation because I want to separate model from data access.
I am having trouble with something in the Seed
method in the Configure.cs
for my entity framework 6 code-first migration process. I am running the Update-Database -verbose
command in the Package Manager Console
, and tried to set breakpoints (in VS studio web express 2013) in the c# code of the Seed
method. But even if I put it on the first statement in the method, it is not hit, although the console displays running seed method
(and subsequently breaks due to my error)
Hi I’m using the Beta 1 version of this nuGet package, the database is allready created and I need to know if there is a way to populate my tables through migrations. Thanxs
I’m attempting to implement a multi-tenant application where I query the db via the tenant object, instead of directly off the context. Before I had this:
