I'm using entity framework core 2.1 and my database context contains of the follwing classes
public class MultiStringSetting
{
public int Id { get; set; }
public virtual IEnumerable<MultiString> Values { get; set; }
}
public class MultiString
{
public int Id { get; set; }
public string Value { get; set; }
}
Consider the following: I have 3 MultiString objects in my database with id's 1, 2 and 3. My current MultiStringSetting has MultiString 1 in its Values. What i would like to do now is set the Values of my MultiStringSetting to 2 and 3, without removing MultiString 1 from my database. How can i achieve this? I tried some things like attach and update but both had no success for me.
Bonus question: What if i have the same scenario as above however i now have a list of MultiStringSetting and i want to update them all.
