How to compare POCO class with Database?

Question

I need to compare what's on my POCO classes against my database. I am currently using Microsoft Roslyn and Microsoft.SqlServer.SMO and comparing the data, in my opinion, 'roughly'. It's working perfectly, but I was wondering if there was a better way to do so.

Today I have to compile the file using Roslyn, load the database info and compare what I want.

Let's say I have this POCO file:

[Table("XPTO", Schema="ASD")]
public class MyPoco 
{
    public int PropId {get; set;}
    public virtual Prop Prop {get; set;}
    public DateTime? MyDate {get; set;}
}

And I also have the Table info. I want to see if what is nullable in my POCO class (MyDate) is nullable on my database and vice-versa. I want to see if my database has a Foreign Key to table Props and if it is not-nullable as in my POCO.

As I said, it's already working today, I just wanted to rewrite the code to use a more effective way to even maintain.

Does EntityFramework provide some sort of API or anything?

If I'm reading your question right - you'd want some API to fetch the relationshiops and other metadata information from the DbContext or EF/code-first at runtime?

The best I've seen so far - and the best the two of us could do was this...

How I can read EF DbContext metadata programmatically?

...take a look if this can help you...
