How to delete a single Record using Entity Framework?

You can delete the single record using Entity framework by selecting that record first and then using .Remove () method

using (var Context= new DataBaseEntities())
{
  var itemToRemove = Context.Table_Name.Where(a => a.id == 1).FirstOrDefault(); //returns a single item.

 if (itemToRemove != null) {
    Context.Table_Name.Remove(itemToRemove);
    Context.SaveChanges();
  }
}

OR

you can use context.Entry(employer).State = EntityState.Deleted

using (var Context= new DataBaseEntities())
{
 var itemToRemove = Context.Table_Name.Where(a => a.id == 1).FirstOrDefault(); //returns a single item.

 if (itemToRemove != null) {
    Context.Entry(itemToRemove).State = EntityState.Deleted;
    Context.SaveChanges();
 }
}

OR

 var ObjectTORemove= Context.Table_Name.Where(a => a.id == 1).FirstOrDefault();

  //Delete it from memory
  entities.DeleteObject(ObjectTORemove);
  //Save to database
  entities.SaveChanges();

You can use 'SingleOrDefault' instead of 'FirstOrDefault' in above C# Code, for safer output.

You can also have generic method to delete single record using Entity framework

public virtual void DeleteSingleRecord<T>(int id) where T : BaseEntity, new()
{
    T instance = Activator.CreateInstance<T>();
    instance.Id = id;
    if (dbContext.Entry<T>(entity).State == EntityState.Detached)
    {
        dbContext.Set<T>().Attach(entity);
    }

    dbContext.Set<T>().Remove(entity);
}

That should work.
