How Can I Update a Single Field in a Database Record Using Entity Framework?

Update a single field using Entity Framework

Background Entity Framework allows developers to interact with databases using an object-oriented approach. When working with a database table, you may need to update only specific fields in a record.

Solution To update only one field using Entity Framework, follow these steps:

1. Load the entity into the context: Retrieve the entity instance corresponding to the record to be updated.
2. Attach the entity to the context (optional): If the context does not already track the entity, you need to attach it using Attach().
3. Modify the required field: Access the field you want to update and set its new value.
4. Mark a field as modified: Call IsModified on the Entry property and set it to true to indicate the field you modified.
5. Saving changes: Call SaveChanges() on the context to commit changes to the database.
