📚 How to Retrieve the ID of an Inserted Entity using Entity Framework

🖊️ Hey there, tech enthusiasts! 👋 Are you grappling with retrieving the ID of an inserted entity using Entity Framework in ASP.NET? 😕 Fret not! In this blog post, we'll dive into common issues and provide easy solutions to help you overcome this hurdle. So, let's get started! 🚀

🎯 The Problem: Getting the ID of an inserted entity 🆔

🤔 Picture this: You're using Entity Framework in your ASP.NET application and you want to fetch the ID value as soon as you add an object to the database. But how can you accomplish this task? 😮

🔎 The Solution: Unlocking the Secrets of Entity Framework 🗝️

According to the official Entity Framework documentation, you can capture the ID as shown in the example below:

using (var context = new EntityContext())
{
    var customer = new Customer()
    {
        Name = "John"
    };

    context.Customers.Add(customer);
    context.SaveChanges();
        
    int id = customer.CustomerID;
}

🔎 Let's Break it Down: How Does it Work? 🧐

When using Entity Framework, this code snippet demonstrates the basic technique to grab the assigned ID of an entity after it's been added to the database. The SaveChanges() method persists the changes made to the database.

🤯 But... One Important Note: Entity ID vs. Database Table Identity 💡

It's crucial to understand that this method retrieves the assigned ID of the entity rather than the database table identity. 🔄 So, if you delete a record from the table, the seed identity will not match the entity's ID anymore.
